Opis:: Bioassays were conducted to assess the effects of two silicon dioxide nanoparticles of Aerosil® and Nanosav against adults of Rhyzopertha dominica F. and Tribolium confusum Jacquelin du Val. Silica nanoparticles were applied at the rates of 50, 100, 200 and 300 mg · kg–1 on wheat and peeled barley. The mortality was counted after 1, 2, 3, and 7 days of exposure. Another experiment was carried out to evaluate the effect of food source on the survival of beetles after exposure to silica nanoparticles. Adults were exposed to silica nanoparticles at the rate of 0.2 mg · cm–2 for 1 and 2 days on filter paper inside plastic Petri dishes, respectively. After exposure, the initial mortality was counted and live individuals of both species were held for a week in empty glass vials or vials containing wheat and wheat flour, respectively. Silica nanoparticles have high toxicity on R. dominica and T. confusum adults. Rhyzopertha dominica was more susceptible than T. confusum. However, the mortality of both species increased with increasing concentrations and time exposed to each concentration. At low concentrations, Aerosil® was more effective than Nanosav. Silica nanoparticles were more effective in wheat grains than barley. Results indicated that the initial mortality was so high that the impact of food source on delay mortality was unclear in most cases. Silica nanoparticles were efficient against tested species and can be used effectively in a stored grain integrated pest management program.

Opis:: The chemical composition of worm wood Artemisia annua L. (Astraceae), a medicinal plant, was studied by gas chromatography and gas chromatographymass spectrometry (GC-MS). About 60 compounds were identified, from which the major compounds were erythritol (50.30%), camphore (7.25%), pinocarveol (4.13%) and diethoxyethane (2.18%). The effect of crude extract on deterrency was maximal in 1000 μL/L treatment (only 4.66 ±1.05 insects were attracted to treated food) compared to control (12.6 ±0.96) The growth regulatory effect showed that 1600 μL/L treatment variously affected the weight of larvae, pupae and adult (0.48 ±0.003, 2.17 ±0.02 and 1.31 ±0.015, respectively) and finally the ovicidal effect and the number of adults appearing in F1 were similarly affected (38.5 ±1.7 and 33.75 ±2.31), comparing to control (99.25 ±1.727 and 92.5 ±1.35). The present result and previous results on this plant species indicate that it can be a good candidate for controlling stored product insects.

Opis:: The aim of the work was to study the feeding deterrent activity of precocenes, their synthetic analogues, and some related compunds to storage pests: Sitophilus granarius L., Tribolium confusum Duv., Trogoderma granarium Ev., and aphids: Myzus persicae (Sulz.). Among all tested compounds precocenes I and II exhibited the best feeding deterrent activity against all tested insects. 4-Chromanols (16, 17 and 18), alcohols 19, 20 and 3-chromanone ( 15) showed high deterrence towards the larvae of T. confusum. The best antifeedant activity towards the adults of both T. confusum and S. granarius was observed for substituted phenols with methoxy group at benzene ring. The biological tests carried out on aphids showed that the presence of methoxy group in the molecule was a crucial structural factor for the appearance of antifeedant activity against these insects.
Prekoceny i ich analogi oraz niektóre związki fenolowe poddano testom biologicznym na aktywność deterentną. Badania przeprowadzono na trzech szkodnikach magazynów zbożowych: larwach skórka zbożowego (Trogoderma granarium Ev.), larwach i chrząszczach trojszyka ulca (Tribolium confusum Duv.), chrząszczach wołka zbożowego (Sitophilus granarius L.) oraz na mszycy brzoskwiniowo-ziemniaczanej (Myzus persicae Sulz.). Testy wykazały, że najbardziej aktywnymi antyfidantami w stosunku do larw trojszyka ulca są 4-chromanole (16, 17 i 18), alkohole 19 i 20 oraz 3-chromanon (15). Fenole z grupami metoksylowymi wykazały wysoką aktywność zarówno w stosunku do larw, jak i chrząszczy trojszyka ulca. Połączenia te okazały się również, jako jedyne z testowanych, aktywne w stosunku do mszyc. Wskazuje to na grupy metoksylowe jako elementy strukturalne decydujące o aktywności deterentnej badanych połączeń fenolowych.

Opis:: Humans and animals come into contact with various compounds in their natural environment. Most of the encountered substances are neutral, yet some may carry adverse health effects. The ingested food may be a source of harmful substances, including benzoquinones which, as shown by research results cited in this paper, demonstrate toxic, carcinogenic and enterotoxic activity. This group of compounds is inclusive of 2-methyl-1,4-benzoquinone (MBQ) and 2-ethyl-1,4-benzoquinone (EBQ), defensive secretions of the confused flour beetle (Tribolium confusum J. du V) and the red flour beetle (Tribolium castaneum Herbst). Benzoquinones have a carcinogenic effect, they are inhibitors of growth of various microorganisms, they produce a self-defense mechanism in threat situations and affect population aggregation. As noted by the referenced authors, the properties of benzoquinones have not been fully researched to this date.

Opis:: The artificially made kernels from ground wheat grain, commercial wheat starch and wheat proteinaceous α-amylase inhibitors in different proportions were used as feed for adults of the granary weevil (Sitophilus granarius L.). In the case of larvae of the confused flour beetle (Tribolium confusum Duv.) and the Mediterranean flour moth (Anagasta kuehniella Zell.) the friable feed mixture were used. The survival of S. granarius adults has not been correlated with the soluble proteins extracted from wheat and amylolytic activity located in this protein fraction. On the other hand the weight of dust (the index of feeding intensity) produced during feeding has depended on the presence of α-amylase and trypsin inhibitors in wheat-based feed. A. kuehniella larvae have not developed at all on feed consisted of 50% wheat starch and 50% of crude a-amylase inhibitors from wheat. The same feed has caused 15.1 days of extension in development time of T. confusum larvae. lt attests to specific native enzymatic apparatus existing in alimentary canals of three damaging grain species which can overcome some obstacles even if extremely highly active insect α-amylase inhibitors were present in feed. However, the sufficient nutrient should be available in feed compounds. Nevertheless, some reduction of insects population can be expected.
Sztuczne ziarna zrobione z handlowej skrobii pszennej i białkowych inhibitorów α-amylaz wymieszanych w różnych proporcjach oraz czyste ziarno pszenicy stanowiły pokarm wołka zbożowego (Sitophilus granaris L.). Dla larw trojszyka ulca (Trbolium confusum Duv.) i mklika mącznego (Anagasta kuchniella Zell.) te same produkty podawano w postaci sypkiej. Procent przeżywalności chrząszczy wołka zbożowego nie zależał od zawartości białka rozpuszczalnego ani od aktywności amylolitycznej pokarmu. Z drugiej strony ilość pyłu wytworzonego w czasie żerowania (wskaźnik intensywności żerowania) zależał od obecności inhibitorów α-amylazy i trypsyny. Larwy mklika mącznego nie kończyły rozwoju na pokarmie zawierającym 50% skrobii pszennej i 50 inhibitorów α-amylazy. Ten sam pokarm powodował przedłużenie rozwoju larw trojszyka ulca o 15,1 dnia. To świadczy o istnieniu wrodzonego, specyficznego aparatu enzymatycznego w przewodzie pokarmowym testowanych owadów, który może pokonać nawet ekstremalnie wysoką aktywność inhibitorów α-amylazy obecnych w pokarmie. Efektem działania inhibitorów może być tylko redukcja liczebności populacji.
