اگر چه مقاومت ژنتیکی ارقام گیاهی مطمئن ترین، سالم ترین و ارزان ترین روش کنترل آفات محسوب می شود ولیکن در مدیریت تلفیقی موفق آفات، ارقام گیاهی مقاوم به آفت بایستی با عوامل کنترل بیولوژیک سازگار باشند. در تحقیق حاضر میزان جلب کنه شکارگر، phytoseiulus persimilis، و همچنین میزان تولید رایحه های القایی، که عامل جلب کنه شکارگر به گیاه هستند، در 4 رقم لوبیا (ناز، خمین، اختر و g11867)، پس از آلودگی به ...
Abstract Zoophytophagous arthropods can elicit plant defense responses affecting potential prey beyond predation. Phytophagy prevails as the main trigger for these responses, in case of Euseius stipulatus (Athias-Henriot) (Mesostigmata: Phytoseiidae), a predator occurring citrus. Because other triggers cannot be excluded, our aim was to examine whether phytoseiids co-occurring with E. but not e...
Plants under herbivore attack are able to initiate indirect defense by synthesizing and releasing complex blends of volatiles that attract natural enemies of the herbivore. However, little is known about how plants respond to infestation by multiple herbivores, particularly if these belong to different feeding guilds. Here, we report the interference by a phloem-feeding insect, the whitefly Bem...
Predator-prey systems having a specialist predator often are over-exploitive, unstable and transient while similar systems having a generalist predator show less ßuctuation, more stability and regulation of prey at lower densities. These population dynamics also affect dispersal patterns between specialist and generalist predators. In this study, ambulatory and aerial dispersal were assessed fo...
In mutual intraguild predation (IGP), the role of individual guild members is strongly context dependent and, during ontogeny, can shift from an intraguild (IG) prey to a food competitor or to an IG predator. Consequently, recognition of an offspring's predator is more complex for IG than classic prey females. Thus, IG prey females should be able to modulate their oviposition decisions by integ...
