    Opis:
    The pyrokinin (PK) family plays a multifunctional role in an array of important physiological processes in a variety of insects. A PK active core analog containing an (E)-alkene, transPro isosteric component was evaluated in five disparate PK bioassays and/or in a recombinant PK receptor cell line, representing six different insect species. The assays included pheromone biosynthesis in the moth Heliothis peltigera, melanization in the larval Spodoptera littoralis, pupariation acceleration in the larval fly Neobellieria bullata, diapause termination in the moth Heliothis zea, and hindgut contraction in the cockroach Leucophaea maderae. This constrained analog demonstrated unselective agonist activity that approached, matched, or exceeded the activity of parent PK peptides of equal length in all six PK assays. The results provide strong evidence for the orientation of Pro and the core conformation adopted by PK neuropeptides during interaction with disparate PK receptors. A PK active core analog incorporating a second transPro motif, the dihydroimidazoline moiety, was found to demonstrate pure, selective agonism in the melanotropic bioassay, with no significant activity in three other PK bioassays. Both types of transPro isosteric analogs feature modification adjacent to the primary tissue-bound peptidase hydrolysis site that is expected to enhance biostability over natural PK peptides. The research further identifies two novel scaffolds with which to design either selective or non-selective mimetic PK analogs as potential leads in the development of environmentally favorable pest management agents capable of disrupting PK-regulated systems.

    Opis:
    Pheromone traps are used for monitoring I. typographus populations in Norway spruce stands of the Tatra National Park (TPN) in Poland. The presented study is based on the set of pheromone traps of precisely known location (23) located in the whole area of the TPN and operated continuously in 2010–2019. The data on the captures of beetles were compared with two kinds of data concerning the mortality: the area covered by standing dead trees (airborne photographs) in the no-intervention zone, and the volume of trees infested by bark beetles processed in the active protection zone. No relationship was found between the mean numbers of beetles captured yearly in all pheromone traps in the whole TPN area and the volume of infested trees removed from the stands in the active protection zone. The captures in the two selected study areas were correlated with the area of spots with dead trees in the 500 m circle around the traps, however, this correlation is not statistically significant. There is no relation of captures to the volume of processed infested trees. The captures decreased in the growing seasons after the wind damage, and increased markedly after the drought started in 2015. The results of pheromone trapping are affected by several factors, as wind damage and defence potential of trees resulting from their physiological status. Pheromone traps represent valuable source of information about the bark beetle I. typographus population dynamics, although the collected data do not enable direct definition of its population level, especially in the protected areas with different and unstable (changed in 2017) approach to the protection of stands. As most of the information on beetles is captured in the first half of the growing season, the data collected till the end of July are sufficient for monitoring purposes; thus, the trapping should be reduced to the period May–July.

    Opis:
    An acquaintance network is a social structure made up of a set of actors and the ties between them. These ties change dynamically as a consequence of incessant interactions between the actors. In this paper we introduce a social network model called the Interaction-Based (IB) model that involves well-known sociological principles. The connections between the actors and the strength of the connections are influenced by the continuous positive and negative interactions between the actors and, vice versa, the future interactions are more likely to happen between the actors that are connected with stronger ties. The model is also inspired by the social behavior of animal species, particularly that of ants in their colony. A model evaluation showed that the IB model turned out to be sparse. The model has a small diameter and an average path length that grows in proportion to the logarithm of the number of vertices. The clustering coefficient is relatively high, and its value stabilizes in larger networks. The degree distributions are slightly right-skewed. In the mature phase of the IB model, i.e., when the number of edges does not change significantly, most of the network properties do not change significantly either. The IB model was found to be the best of all the compared models in simulating the e-mail URV (University Rovira i Virgili of Tarragona) network because the properties of the IB model more closely matched those of the e-mail URV network than the other models.

    Two-component blends of (2E,13Z)-2,13-octadecadienyl acetate (E2,Z13-18:Ac) and (3E,13Z)-3,13-octadecadienyl acetate (E3,Z13-18:Ac) used in pheromone dispenser were as attractive to males of Synanthedon tipuliformis as standard lure from the Csalomon company, based on field trapping tests. The attractiveness of dispensers with pheromone blend combined in a E2,Z13-18:Ac/E3,Z13-18:Ac - mixture ratio 97:3 at dose of 1000 µg was the highest. Field experiments were performed in central Poland at three commercial black currant plantations and one commercial plantation of gooseberry (no plantation was treated with an insecticide) during the seasons of 2015 and 2017. The use of lures tested to evaluate effectiveness of a pest management programs (monitoring) is discussed.

Najlepsze własności wabiące miała dwuskładnikowa mieszanina zawierająca E2,Z13-18:Ac i E3,Z13-18:Ac w proporcji 97:3 i w dawce 1000 µg, dozowana do szarego korka gumowego i umieszczona w lepowej pułapce typu delta. Badania polowe przeprowadzono w centralnej Polsce w trzech produkcyjnych plantacjach czarnej porzeczki i jednej plantacji agrestu (na żadnej z plantacji nie stosowano środków chemicznych do zwalczania szkodników) w latach 2015 i 2017. W pracy omówiono możliwość zastosowania dwuskładnikowych feromonów wabiących motyle S. tipuliformis jako wabika wykorzystywanego w pułapkach z feromonem na produkcyjnych plantacjach porzeczki i agrestu do monitoringu lotu motyli.

    Opis:
    Ips duplicatus adults were sampled with pheromone-baited black window-slot traps (Theysohn) in 70- to 100-yearold Norway spruce (Picea abies) stands between 280 and 650 m a.s.l. in the eastern Czech Republic and southern Poland during 2000– 2010. Sets of 5–12 traps were placed about 20 m from the edge of the infested forest. Each trap was baited with a standard synthetic pheromone lure (ID Ecolure), and was setup 1.5–2.0 m above the ground. The objectives were to determine the relationship between the numbers of adults trapped in the overwintered generation and those in the offspring generation. According to data from 135 traps, the numbers of overwintered beetles captured in spring (April–June) were significantly higher than the numbers captured in summer (July–August), but the numbers of offspring beetles captured in summer were significantly correlated with the numbers overwintered beetles captured in spring. The spring captures can be used to estimate the threat caused by I. duplicatus during the whole vegetation season. The traps installed in summer should be used to determine the peaks in the bark beetle flight activity, thus enabling early identification of trees infested by I. duplicatus, especially inside stands.

    Opis:
    Bark beetles (order Coleoptera, family Scolitydae) comprise a taxonomic group of species that look similar although they differ widely in their ecology and biochemical adaptations to host tees. This diversity of bark beetle biology in which each species is adapted to only one or a few host species, has probably resulted from natural selection due to the great variety of trees and their biochemicals. It also is likely that each species of tree has coevolved various chemicals to defend against the herbivorous selection pressures of bark beetles and other insects. Host plant chemicals can be attractive, repellent, toxic or nutritious to bark beetles and have effects on: (1) finding and accepting the host tree (host selection and suitability), (2) feeding stimulation and deterrence, (3) host resistance, (4) pheromone/allomone biosynthesis and communication, and (5) attraction of predators, parasites and competitors of bark beetles. There are two theories on how bark beetles find suitable host trees. The first is that they locate such trees by orienting over several metres to volatile chemicals usually released by damaged or diseased trees (called "primary attraction"). The second theory is that beetles fly about and encounter suitable host trees at random, whereupon they land and test them by short−range olfaction or gestation.

    Opis:
    The horse chestnut leaf miner, Cameraria ohridella Deschka & Dimic (Lepidoptera: Gracillariidae), is a new invasive pest that has spread all over the Europe over the last 25 years. This paper presents research aimed to: 1) compare the effectiveness of sticky pheromone traps of various types (sizes and colors), 2) determine the effect of a trap location on moth catches. Studies were conducted in Warsaw and Falenty near Warsaw. No trap color preference by male moths was found in tests of white, blue and green barrier traps. Barrier traps had the largest sticky area (32 dm2) in comparison to PL-2 (5.625 dm2) and delta PL-1 (3.4 dm2) traps, thus they caught the highest total number of males, however PL-2 traps were the most effective (268-381 moths/dm2). The results of the studies suggest that to make traps with the C. ohridella pheromone be more effective they should: a) be located on a stem below a tree crown or in its lower part for the first C. ohridella generation, and in crowns for the second and later insect generations, b) be placed in some distance from a tree stem, if located in crowns.

The both propheromones were synthesized at the Institute of Industrial Organic Chemistry (IPO) and then tested in 2006/07 on field trials at several different sites on terrain of Mazovian province. Within the scope of these investigations, acetal 2 was checked at different doses (10, 100, 500 μg) by the pheromone trapping technique, and aldoxane 3 was used both in pheromone trapping (at the dose 50 μg) and mating disruption technique. The good attractiveness properties were obtained for both tested compounds. However, the dose of 2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan had to be a 10 times higher than dose of aldoxane for the same good activity.

    Opis:
    The lack of effective methods of forest protection against bark beetles in Norway spruce stands was the reason for undertaking the studies aimed at the assessment of efficacy of pheromone traps Trinet P that act as an ‘attract and kill' system to reduce the population of spruce bark beetle Ips typographus (Col.: Curculionidae: Scolytinae). The Trinet P trap consists of a triangular stand, on which the net containing alpha−cypermethrin is stretched. Each trap is baited by the synthetic pheromone attracting I. typographus beetles, which fly towards the trap and die due to the contact with the net coated with insecticide. The experiments were conducted in 2011−2012 on 6 experimental plots located in 26−82−years−old Norway spruce stands in Beskid Sądecki Mts. (southern Poland) that were threatened with the bark beetles. The experimental plot consisted of 100 m long stand edge exposed to bark beetle attack, with set of 5 traps installed in line. Similar stand edges without traps were used as control. The experiments were assumed before the I. typographus swarming, i.e. at the turn of April and May of each year. The treatment efficacy was estimated after 5 months by counting infested trees on plots with treatment and control variants. In the most cases the protective effect expressed by significantly lower number of infested trees on the edges with Trinet P traps. The symptoms of infestation by I. typographus were found up to 20% of trees in the stands protected with the Trinet P traps, while more than 80% of trees were attacked by the spruce bark beetle on the control plots. Despite these differences, the infestation density of trees in the stands protected and unprotected with traps was similar. No effect on non−target organisms was observed. The effectiveness of Trinet P traps is similar as of commonly used pheromone traps, thus this novel device can be used for the protection of Norway spruce stands against I. typographus.

    Opis:
    The study presents a new strategy of synthesis of the pine-tree lappet moth sex pheromone via hydrolysis of the (5Z,7E)-1,1-diethoxy-5,7-dodecadiene (propheromone) and their using in biological tests with pheromone traps. The field trials showed that a sticky delta traps with propheromone at dose of 2.4 mg was the most suitable for monitoring of the population of the pine tree lappet moth.

    Opis:
    In 2000 and 2008, the effects of Duplodor pheromone lures in two variants (10 of each) with ID Ecolure (Poland) and ID Ecolure with Pheagr IDU (Czech Republic) used against Ips duplicatus were compared. IBL−3 and Theysohn barrier traps were installed in lines. In both cases, the total number of beetles captured during the entire season or beetles of the hibernating and summer generations were always significantly higher when using the ID Ecolure pheromone lure. The first beetles appeared at the end of April and the last ones in September. Flight activity culminated at either the end of April or beginning of May as well as at the end of June in both years, which reflects the two generations of beetles per year.

    Opis:
    Najczęstszym źródłem mechanicznych uszkodzeń roślin jest żerowanie owadów - agrofagów, których liczebność musi być kontrolowana. Przez ponad 50 lat dominującą strategią zwalczania szkodników było stosowanie pestycydów, które jednak w wyniku długotrwałego stosowania indukują odporność agrofagów na te chemikalia. Skuteczność zintegrowanych metod zwalczania szkodnika wymaga, aby insektycydy były używane z minimalnym wpływem na środowisko i naturalnych wrogów agrofagów (ich pasożytów lub drapieżców). Podejmowane są badania nad zastąpieniem pestycydów nietoksycznymi produktami pochodzenia biologicznego, wprowadza się także zmodyfikowane genetycznie rośliny (GMO), posiadające geny odporności na szkodniki i choroby. Rośliny dysponują szeregiem mechanizmów odporności, jak lignifikacja ściany komórkowej, synteza wosków pokrywających powierzchnię liści, wytwarzanie toksyn i metabolitów wtórnych oraz uruchamianie sygnałów chemicznych emitowanych w celu wabienia naturalnych wrogów agrofagów. Manipulowanie zależnościami w układzie roślina-agrofag-drapieżca/pasożyt agrofaga może usprawnić kontrolę szkodników i zredukować ilość zużywanych pestycydów. Praca zawiera przegląd różnych biologicznych metod zwalczania szkodników.
    Many kinds of pests are one of the main reason of the yield loss of crop plants. Their quantity have to be under control. Fight against pest organisms with toxic chemicals has been the prevailing pest control strategy for over 50 years. However, a prolonged application of pesticides in agriculture often induced parasite resistance to these chemicals. Efficient integrated pest control requires that any insecticide used has an effect on the environment and the natural enemies of the pest as minimum as possible. The intensive studies are undertaken towards the substitute of traditional pesticides for non-toxic biological products. Genetically modified plants with introduced genes of the resistance to pests and diseases are more and more widely used, as well as biological control with a full spectrum of organisms and natural products including pheromones and volatile compounds emitted by plants. Plants possess a range of resistance mechanisms such as a cell wall lignification, synthesis of leaf waxes, toxins and secondary metabolites, and induction of chemical signals in injured plants to attract natural enemies of agro phages. Manipulating with the relations of plant-pest-predator/parasite of agrophage may result in better pest control and the reduced amount of pesticides used.
