An 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 کاملComparison of the wing polyphenic response of pea aphids (<i>Acyrthosiphon pisum</i>) to crowding and predator cues
1. Pea aphids (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) exhibit transgenerational wing polyphenism, in which unwinged females produce genetically identical winged offspring in response to environmental cues such as overcrowding and predation risk that indicate poor habitat quality. 2. Laboratory experiments were carried out to explore the intensity of the wing polyphenic response of pe...
متن کاملApplication of DL-beta-aminobutyric acid (BABA) as a root drench to legumes inhibits the growth and reproduction of the pea aphid Acyrthosiphon pisum (Hemiptera: Aphididae).
DL-beta-aminobutyric acid (BABA) is a non-protein amino acid that is an effective inducer of resistance against a variety of plant pathogens. However, examples of BABA-induced resistance against insect herbivores have not been reported. We applied BABA as a soil drench to legumes and monitored its effects on the pea aphid Acyrthosiphon pisum (Harris). On tic bean (Vicia faba var. minor), BABA i...

Generalist predator guilds play a prominent role in structuring insect communities and can contribute to limiting population sizes of insect pest species. A consequence of dietary breadth, particularly in predatory insects, is the inclusion of low-quality, or even toxic, prey items in the predator's diet. Consumption of low-quality prey items reduces growth, development, and survival of predato...
