the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...
the influence of parasitoids on population dynamics is affected by host instar preference. the preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in a particular instar, and also maternal effects of the female forager. in this study, host instar preference of the thelytokous strain of lysip...
cabbage leaf miner scaptomyza flava (fallen) (l)iptera: drosophilidae) is a native and oligophagous leaf miner insect on cruciferous plants (brassicaceae). it occurs in many parts of the world and throughout khuzestan. the relationship between feeding and ovipositional preferences of insect, and host plant suitability on seven host plant species (cauliflower brassica oleracea var. botryds, ...
the strawberry spider mite (ssm), tetranychus turkestani ugarov & nikolski, is an important pest of greenhouse cucumber in tropical and temperate regions of the world. the use of the host plant resistance is a basic method to reduce pesticide application in greenhouses. in this study, the biological responses of ssm to six greenhouse cucumber cultivars (puia, hedieh, milad ghadim, milad jad...
The biological and behavioural parameters of Anisopteromalus calandrae (Hym.: Pteromalidae), a parasitoid of Callosobruchus maculatus (Col.: Bruchidae) on Chickpea were studied in laboratory conditions at temperature of 25±1ºC, photoperiod 16:8 (L:D) and 20±5 % RH. The pre-adult period of the wasp was 19.82 ± 0.038 days and pre-ovipositional period in this wasp was so short that female laid egg...
