Larval morphology and development of Aphidius rhopalosiphi (Hymenoptera: Braconidae: Aphidiinae)1
The aphid parasitoid Aphidius rhopalosiphi is the most abundant species of Aphidiinae in cereal fields in northern Europe. Although the larval morphology of other Aphidiinae has been described, the morphology and immature development of A. rhopalosiphi remain unknown. Our goal is to relate growth and larval developmental stages to morphological changes during parasitoid development, using light...
متن کاملIdentification and validation of reference genes for gene expression analysis in Aphidius gifuensis (Hymenoptera: Aphidiidae)
Reference genes have been utilized in estimating gene expression levels using quantitative reverse transcriptase-quantitative polymerase chain reaction (qRT-PCR) analysis. Aphidius gifuensis Ashmaed is one of the most widely used biological control agents for aphids. The biological properties of this species have been studied in detail, and current investigations are focused on elucidating the ...
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 کاملHost-parasite interactions between whiteflies and their parasitoids.
There is relatively little information available concerning the physiological and biochemical interactions between whiteflies and their parasitoids. In this report, we describe interactions between aphelinid parasitoids and their aleyrodid hosts that we have observed in four host-parasite systems: Bemisia tabaci/Encarsia formosa, Trialeurodes vaporariorum/E. formosa, B. tabaci/Eretmocerus mundu...
متن کاملExpression differences in Aphidius ervi (Hymenoptera: Braconidae) females reared on different aphid host species
The molecular mechanisms that allow generalist parasitoids to exploit many, often very distinct hosts are practically unknown. The wasp Aphidius ervi, a generalist koinobiont parasitoid of aphids, was introduced from Europe into Chile in the late 1970s to control agriculturally important aphid species. A recent study showed significant differences in host preference and host acceptance (infecti...
