Defences against parasites are typically associated with costs to the host that contribute to the maintenance of variation in resistance. This also applies to the defence provided by the facultative bacterial endosymbiont Hamiltonella defensa, which protects its aphid hosts against parasitoid wasps while imposing life-history costs. To investigate the cost-benefit relationship within protected ...

Life history parameters of the ladybird populations, Propylea quatuordecimpunctata (L.) (Coleoptera: Coccinellidae), collected at two locations in Iran (Karaj and Sari) were recorded on two prey species, Aphis fabae Scopoli, 1763 and Aphis gossypii Glover, 1877 (Homoptera: Aphididae). The duration of most developmental stages (egg, first, second and third instar larva...

The objective of our work was the valorisation four aromatic plants growing spontaneously in Kabylia (Algeria) by evaluation their insecticidal activity against black bean aphid Aphis fabae Scopoli, 1763. These are oregano, thyme, rosemary and lavender. were subjected to a phytochemical analysis determine secondary metabolites composition. results obtained showed that extracts toxic A. can sign...

Artičoka (Cynara scolymus L.) je višegodišnja biljna vrsta koja zahvaljujući svojim prehrambenim ali i zdravstvenim značajkama postaje sve raširenija kultura na području primorske hrvatske otoka. Tijekom svog razvoja artičoka podložna napadu brojnih štetnika među kojima su gospodarski značajni nekoliko lisnih ušiju leptira. Lisne uši kao fiziološki štetnici sisanjem listova cvjetnih glavica pos...

Wildflower strips and biodiversity-friendly management are promoted as ways of enhancing biodiversity natural pest control in agroecosystems. Their efficacy for providing resources shelters enemies has been well studied, but little is known about how wildflower strip mediated by local field landscape composition. In this study, we explored the effects floral perennial flower on faba bean aphids...

host plant's quality in the food chain of a herbivorous insect influences the insect's life performance, and thus abundance in its population. the effect of different ratios of n: k fertilization (40:60), (40:40), (40:0) kg/ha vs. control (0:0) were determined on chemical content parameters (n, k and c %) of the bean plant and as well on the performance of aphis fabae scop. experiment...

to provide reliable information concerning reproductive potential of hippodamia variegata goeze and its prey (aphis fabae), their related life tables were studied under controlled laboratory conditions (at 23?c). the unprocessed data of life tables were analyzed taking the euler-lotka as the basis model. standard error of population growth parameters was calculated using the jackknife re-sampli...

BACKGROUND The species diversity of aphids and seasonal timing of their flight activity can have significant impacts on crop production, as aphid species differ in their ability to transmit plant viruses and flight timing affects virus epidemiology. The aim of the study was to characterise the species composition and phenology of aphid fauna in Finland in one of the northernmost intensive crop ...

The article highlights the theoretical generalization and a new solution to problem, which is develop substantiate elements of system protection sugar beet from pests control their numbers in Vinnytsia region, based on number when using insecticides for seed treatment spraying crops with chemical biological drugs. species composition harmful entomofauna has been specified 14 have identified, in...
