Opis:: Tuberolachnus salignus is a cosmopolitan aphid that predominantly feeds on the willow. It can be an economically im-portant pest of this plant. The aim of the study was to present the thematic scope of the literature on this species in Poland and in the world. The typical issues related to aphid biology (life cycle, nutrition, distribution) and its potential harmfulness are consid-ered. Additionally, aphid genetics, dyes, natural enemies, indirect influence on the soil environment as well as the use of this insect species in research on plant physiology are taken into account. It was found that in recent years, the studies on giant willow aphid have been mainly motivated by the potential utilisation of the results in the protection of willow against this aphid. Despite a wide range of topics, the publications collected in the SCOPUS and Web of Science databases are not sufficient sources of in-formation about this species. The available data must be supple-mented and updated using modern research methods. The experi-ments and observations should consider the direct and indirect relationships of T. salignus with other organisms and the environment.

Opis:: Azadirachtin is the most active substance separated from Azadirachta indica. lt acts destructively on numerous species of insects and mites. The aim of the presented investigations was to determine the effect of azadirachtin on one of the most dangerous pests of cabbage plants, Pieris brassicae, and on its natural enemy, Apanteles glomeratus. The results of the field observations did not show any repellent effect of azadirachtin relating to laying their eggs cabbage butterflies. However, a significant effect of the azadirachtin solution on reduction the number of cabbage butterfly caterpillars (it was more distinctly marked in respect to young larva stages) as well as on limited feeding by caterpillars. No negative influence of azadirachtin on a parasite of Pieris brassicae caterpillars, Apanteles glomeratus was distinctly shown.
Azadirachtyna jest najbardziej aktywną substancją wyizolowaną z Azadirachta indica. Działa szkodliwie na liczne gatunki owadów i roztoczy. Celem przedstawionych doświadczeń było określenie jej wpływu na jednego z najgroźniejszych szkodników roślin kapustnych bielinka kapustnika (Pieris brassicae) oraz na jego wroga naturalnego baryłkarza bieliniaka (Apanteles glomeratus). Wyniki przeprowadzonych obserwacji polowych nie wykazały repelentnego działania azadirachtyny w stosunku do składających jaja motyli bielinka. Stwierdzono natomiast znaczący wpływ preparatu na redukcję liczby gąsienic bielinka kapustnika (wyraźniej zaznacza się to w odniesieniu do młodszych stadiów larwalnych) oraz na hamowanie pobierania pokarmu przez gąsienice. Nie wykazano wyraźnie negatywnego wpływu azadirachtyny na pasożyta gąsienic bielinka – baryłkarza bieliniaka.

Opis:: Th e present exploration is focused on the bio-fabrication of silver nanoparticles (Ag NPs) using Trichodesma indicum aqueous leaf extract as a reducing agent. Th e synthesized Ag NPs were productively characterized by UV-vis spectroscopy, XRD, and TEM studies. Th e photosynthesis of Ag NPs was done at room temperature for 24 h and at 60°C. Th e green synthesis of spherical-shaped Ag NPs bio-fabricated from T. indicum with a face centred cubic structure showed average particle sizes of 20–50 nm, which is inconsistent with the particle size calculated by the XRD Scherer equation and TEM analysis. We further explored the larvicidal effi cacy of biosynthesized Ag NPs with leaf extracts of T. indicum against Mythimna separata. Th e results showed that Ag NPs (20–50 nm) of T. indicum possess good larvicidal activity against M. separata with an LC50 of 500 ppm. Th us, we can advocate that Ag NPs of 20–50 nm size extracted from T. indicum may be considered in the pest management programme of M. separata in future.

Opis:: Leaf beetles and fruitfly infestation greatly limits water melon (Citrullus lanatus) production throughout the tropics. The efficacy of aqueous plant extracts applied at 5 % w/v concentration of two botanicals (neems seed oil and garlic bulb) and 1.5 melt of one synthetic insecticide (karate 2.5 EC) against their infestation were evaluated. The effects of these treatments including control on the number of the insects, number of leaves, vines, length of vines, number of fruits, fruit weight, fruit damaged and undamaged were assessed during 2012 and 2013 cropping seasons in Lawanti, Gombe state, Northern Guinea Savannah region of Nigeria. Result of the study showed that neem seed oil and garlic bulb treatments at 5 % w/v were effective against the leaf beetles and water melon fruitfly as the synthetic insecticide karate 2.5 EC in managing the water melon insect pests. Karate 2.5 EC significantly reduced the infestation of the insect pests of water melon and increased number of leaves, vines, length of vines, number of fruits, fruit weight and number of undamaged fruits/plot followed closely by neem seed oil (A. indica) and garlic bulb (A. sativum) extracts. Water melon a growth and fruit yields were appreciably improved in these treatment while untreated control water melon crops had more leafs beetles and fruitfly infestations, poor plant growth and lower fruit yields. Both botanicals can thus serve as alternatives to synthetic insecticides for managing water melon leaf beetles and fruitfly attack.

Opis:: The objectives of this work were to describe the residual behaviour of chlorpyrifos (insecticide) and chlorothalonil (fungicide), applied for the protection of carrot and parsley plantations. The field tests were carried out at farms located near Rzeszów (South-Eastern Poland) on processing carrot and parsley destined for baby food production. The results obtained indicated that disappearance rate of chlorothalonil on carrot leaves was significantly faster and its half-life time was about 7 times shorter than that of chlorpyrifos. In weather conditions of 2006, chlorpyrifos residues in rape carrot and parsley roots were reduced to levels lower than MRL and even the rigorous value of 0.01 mg/kg.

Opis:: Określono wrażliwość prusaków (Blattella germanica L.) różnorodnych pod względem wieku i płci, na owadobójczy biopreparat z Bacillus thuringiensis var. kurs taki (Dipel).
In the studies conducted for finding of biological factors effectively controlling insects of hygienic importance German cockroaches were subjected to the action of an insecticide containing spores of Bacillus thuringiensis var. kurstaki. One gram of the insecticide contained 25 miliard (US billion) spores with protein endotoxin crystals. The inscets were given drinking water and food containing 1.0%, 0.5%, 0.25%, 0.125% of the initial preparation. The experiment was carried out on 1800 cockroaches. Half of them (600 mature insects differentiated for sex and age and 300 larvae in stage 1st of development) were treated with the preparation, the remaining insects served for control. The insects were kept at about 28°C. After 9 days o the experiment in the group receiving 1% Dipel on food 76.4% mature insects and 83,0% larvae in 1st stage of development died. After 14 days all males died, and after 17 days died all females. In the control group died in that time 2.3% and 3.4% respectively. In case of lower per cent of the preparation in food the time of dying was prolonged, and at the lowest per cent it was 22 days. The study showed that Dipel effectively reduced the population of German cockroaches, and although in initial period its action was slower than that of chemical agents, it could be used for the control of these insects, especially as it in non-toxic for humans, warm-blooded animals and useful insects.

Opis:: Efforts have been made during the past three decades to develop insecticides with selective properties that act specifically on biochemical sites present in a particular insect group, but whose properties differ from those present in mammals. This approach has led to the discovery of compounds that affect the hormonal regulation of molting and developmental processes in insects such as ecdysone agonists, juvenile hormone (JH) mimics and chitin synthesis inhibitors. The search for potent acylureas has led to the development of novaluron (Rimon) developed by Makhteshim Chemical Works. The LC-50 value of novaluron on 3rd-instar Spodoptera littoralis fed on treated leaves is approximately 0.1 mg a.i./liter. This value resembles that of chlorfluazuron and is tenfold lower than that of teflubenzuron. Novaluron affects nymphs of Bemisia tabaci more than chlorfluazuron and teflubenzuron. Artificial rain, at a rate of 40 mm/h applied 5 and 24 h after treatment in a cotton field had no appreciable effect on the potency of novaluron on both S. littoralis larvae and B. tabaci nymphs. Hence, novaluron can be used in tropical areas and during rainy seasons. In general, benzoylphenyl ureas had no direct effect on parasitoids and phytoseiids and are considered mildly affect other natural enemies. Novaluron has no cross-resistance with conventional insecticides, the JH mimics pyriproxyfen and neonicotinoids. As such, it is considered an important compound in pest management programs.
