یادگیری و دوام حافظة زنبورTrichogramma brassicae )Hym.: Trichogarmmatidae) آلوده به باکتری Wolbachia
توانایی یادگیری و به‌خاطر‌سپردن نشانه‌های مرتبط با حضور شکار یا میزبان از عوامل مؤثر در افزایش کارایی و قدرت جست و جوگری دشمنان طبیعی همچون پارازیتوییدهای تخم از جمله زنبورهای Trichogramma در طبیعت است. زنبور Trichogramma brassicae در ایران گونة غالب در بین گونه‌های مختلف جنس Trichogramma است و بیشترین گسترش را در مناطق مختلف ایران دارد. در حال حاضر، این گونه پرکاربردترین پارازیتویید تخم در بر...
Fecundity and sex ratio are the important factors in the quality control of parasitoid, Trichogramma. In this research, the effect of the host egg deprivation on these factors in Trichogramma brassicae Bezdenko was evaluated. The experiment was conducted with four treatments, each in five replications in a completely randomized design. Twenty mated females (24 h old) were transferred into the g...

Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley - as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to ...
The parasitoid wasp Trichogramma minutum Riley (Hymenoptera: Chalcidoidea: Trichogrammatidae) adjusts its progeny allocation and host examining behaviour to the exposed volume of its host — an insect egg. The female wasp examines a potential host by walking over its surface while drumming its antennae against it, spending a longer time examining larger hosts. If wasps of different sizes are pre...
To successfully exert defenses against herbivores and pathogens plants need to recognize reliable cues produced by their attackers. Up to now, few elicitors associated with herbivorous insects have been identified. We have previously shown that accessory reproductive gland secretions associated with eggs of Cabbage White butterflies (Pieris spp.) induce chemical changes in Brussels sprouts plan...
How does the MIDAW facility improve the performance of FICON channels using DB2 and other workloads?
The Modified Indirect Data Address Word (MIDAW) facility was introduced in the IBM® z9TM processor to improve FICON® performance, especially when accessing IBM DB2® databases. This facility is a new method of gathering data into and scattering data from discontinuous storage locations during an I/O operation. This IBM Redpaper is mainly intended for industry professionals who are interested in ...
