Parasitoids as vectors of facultative bacterial endosymbionts in aphids.
Heritable bacterial endosymbionts play an important role in aphid ecology. Sequence-based evidence suggests that facultative symbionts such as Hamiltonella defensa or Regiella insecticola also undergo horizontal transmission. Other than through male-to-female transfer during the sexual generation in autumn, the routes by which this occurs remain largely unknown. Here, we tested if parasitoids o...
متن کاملPreventive control of aphids in ornamental plants with complementary parasitoids.
Biological control of aphids can be achieved with parasitoids. A parasitoid is a wasp able to parasitize aphids in a host-specific way. These natural enemies of aphids are used in organic or integrated pest management strategies. In order to apply the matching parasitoid against a given aphid species, the aphid has to be detected in the crop and subsequently identified. By the time the aphids a...
متن کاملTrophic Relationships between Aphids and Their Primary Parasitoids
The present research was carried out to study the trophic relationship between aphids and their primary parasitoids in Pothwar, Pakistan during 2009-2010 in the districts of Rawalpindi, Attock, Chakwal, and Jhelum. Ten species of aphids were recorded from 17 host plants. The aphids were parasitized by 11 species of primary parasitoids. Five quantitative aphid-parasitoid food webs were construct...
متن کاملAn investigation on alfalfa aphids and their parasitoids in different parts of Iran, with a key to the parasitoids (Hemiptera: Aphididae; Hymenoptera: Braconidae: Aphidiinae)
در این تحقیق اطلاعاتی در زمینه‌ی پراکنش و رابطه‌ی بین شته‌های یونجه و پارازیتوییدهای آنها در مناطق مختلف یازده استان ایران همراه با کلید شناسایی ارایه می‌گردد. مهمترین شته‌های یونجه عبارت بودند از Therioaphis trifolii maculata (Buckton) و Acyrthosiphon pisum (Harris) و سپس Aphis craccivora Koch و Acyrthosiphon kondoi Shinji. الگوی پراکنش این شته‌ها در مناطق مختلف متفاوت بود. T. trifolii maculat...
متن کاملComparing constitutive and induced costs of symbiont-conferred resistance to parasitoids in aphids
Host defenses against parasites do not come for free. The evolution of increased resistance can be constrained by constitutive costs associated with possessing defense mechanisms, and by induced costs of deploying them. These two types of costs are typically considered with respect to resistance as a genetically determined trait, but they may also apply to resistance provided by 'helpers' such ...
