Parasitoid load affects plant fitness in a tritrophic system
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont parasitoids also confer a benefit to plant fitness has been disputed. We investigated the relationship between parasitoid load of the gregarious Co...
متن کاملImpact of water-deficit stress on tritrophic interactions in a wheat-aphid-parasitoid system
Increasing temperature and CO2 concentrations can alter tritrophic interactions in ecosystems, but the impact of increasingly severe drought on such interactions is not well understood. We examined the response of a wheat-aphid-parasitoid system to variation in water-deficit stress levels. Our results showed that arid area clones of the aphid, Sitobion avenae (Fabricius), tended to have longer ...
متن کاملHost diet aects extinctions and colonizations in a parasitoid metapopulation
1. In the AÊ land islands of SW Finland, the parasitoid Cotesia melitaearum (Wilkonson) is a specialist on the Glanville fritillary butter ̄y, Melitaea cinxia (L.), which uses two host plants, Plantago lanceolata (L.) and Veronica spicata (L.). 2. Extensive survey data on the butter ̄y and parasitoid populations collected in 1994±97 were used to examine possible associations of parasitoid coloniz...
متن کاملHost plant, host plant chemistry and the polyembryonic parasitoid Copidosoma sosares: indirect effects in a tritrophic interaction
Host plant identity and host plant chemistry have often been shown to influence host finding and acceptance by natural enemies but comparatively less attention has been paid to the tritrophic effects of host plant and host plant chemistry on other natural enemy fitness correlates, such as survivorship, clutch size, body size, and sex ratio. Such studies are central to understanding both the sel...
متن کاملImmune system challenge in a host-parasitoid-pathogen system: interaction between Cotesia plutellae (Hym.: Braconidae) and Bacillus thuringiensis influences parasitism and phenoloxidase cascade of Plutella xylostella (Lep.: Plutellidae)
در این پژوهش، اثرات برهم‌کنش بین زنبور پارازیتوئید Cotesia plutellae (Kurdjumov) و باکتریBacillus thuringiensis Berliner بر روی پارازیتیسم و یک مجری سیستم ایمنی (فعالیت آنزیم فنول اکسیداز) جمعیت‌های بید کلم، Plutella xylostella (Linnaeus)، حساس و مقاوم به Btدر آزمایشگاه بررسی گردید. موفقیت پارازیتیسم، بسته به کاربرد Bt یا توکسین آن (Cry1Ac) و همچنین زمان کاربرد آن‌ها، متغیر بود. در جمعیت حساس، ...
