Common bean (Phaseolus vulgaris) production and storage are limited by numerous constraints. Insect pests often the most destructive. However, resource-constrained smallholders in sub-Saharan Africa (SSA) do little to manage pests. Where farmers use a control strategy, it typically relies on chemical pesticides, which have adverse effects wildlife, crop pollinators, natural enemies, mammals, de...
Aphid flight activities in seed potato fields have been studied by the yellow water traps. It is a good method for monitoring aphids as vectors of viruses, but this study also showed it is a suitable method for insect-diversity research. During the four-year studies, over 11.500 specimens were collected and a total of 107 different taxa of aphids were identified. The most abundant species were ...
شته سیاه باقلا یکی از مهمترین آفات محصولات زراعی در سرتاسر جهان است. سن شکارگر deraeocoris lutescens (schilling) (hemiptera: miridae)، جایگاه ممتازی در کنترل بیولوژیکی شته هایی از قبیل شته سیاه باقلا aphis fabae scopoli دارد. در دهه های اخیر در جوامع رو به رشد، گرایش به مصرف هر چه کمتر سموم شیمیایی و استفاده از مشتقات گیاهی به عنوان جایگزین سموم مصنوعی بوده است. در تحقیق حاضر، اثر تلفیق دشمن طب...
In this paper, we formulate a three-species ecological community model consisting of two aphid species (Acyrthosiphon pisum and Megoura viciae) and a specialist parasitoid (Aphidius ervi) that attacks only one of the aphids (A pisum). The model incorporates both density-mediated and trait-mediated host-parasitoid interactions. Our analysis shows that the model possesses much richer and more rea...

Cotton leafroll dwarf virus (CLRDV) is an introduced Polerovirus (Family: Solemoviridae) of cotton, Gossypium hirsutum L., in the U.S. The only vector known to transmit this cotton aphid, Aphis gossypii Glover; however, there are seven other species aphids (Hemiptera: Aphididae) reported colonize southeastern U.S.: Protaphis middletonii (Thomas), Rhopalosiphum rufiabdominale (Sasaki), craccivor...
Abstract The results showed that foliar fertilization with potassium silicate had a clear effect on increasing the thickness of upper and lower epidermal cuticle layer increased leaf, as after first spray reached 22 microns 11 microns, leaf 194.8 microns. As for second spray, 198.66, 25.33, 16.66 third was characterized by an increase in compared to 206.66 epidermis 28.33 19 respectively. Compa...
