We report for the first time, presence of parasitoid Spalangia endius Walker (Hymenoptera: Pteromalidae) in association with invasive fly Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) region North Patagonia (Argentina). This finding is a contribution to study natural enemies this major pest berries and stonefruit crops. Briefly, we describe diagnosis prevalence parasitoid.

we studied the pest and parasitoid fauna of cauliflower fields in southern tehran in 2011. in the course of our research the ichneumonid wasp barichneumon derogator (wesmael) of the subfamily ichneumoninae was collected and identified. this parasitoid attacks the larval stages of lepidopteran pests. the species b. derogator is newly recorded from iran.

a larval parasitoid of carob moth, ectomyelois ceratoniae (zeller), was collected in pomegranate orchards in fars province, iran, during 2009-2010. this parasitoid, which is newly recorded from iran, was identified as goniozus legneri gordh (hym.: bethylidae) by j. de rond (lelystad, the netherlands).

a survey was conducted to identify parasitoids of leafminers in shiraz region during spring 2005. the specimens of the eulophid parasitoid wasp, diglyphus poppoea walker, were reared from wheat leaves infested by agromyza ambigua fallã©n (dip.: agromyzidae) larvae in pole-fasa, zarghan and zafarabad regions. this parasitoid, which is recorded for the first time from iran, was identified by genc...

KURIS, A. M., 1973. Biological control: implications of the analogy between the trophic interactions of insect pest-parasitoid and snail-trematode systems. Experimental Parasitology 33, 365-379. An analogy between the tropic interactions of insect pest-hymenopterous parasitoid and snail-larval trematode systems is proposed. The goal of most agricultural pest management programs is increase in p...

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...

Males of the parasitoid wasp Nasonia vitripennis showed no innate preference for blue versus yellow or for green versus brown. They learned to associate color with mates, but their ability to do so depended on the color used and the strength of the reward. Specifically, males learned to associate brown or green with a reward of many virgin females. With fewer females, fewer training periods, or...

Diachasmimorpha kraussii (Fullaway) (Hymenoptera: Braconidae) was first released against Bactrocera latifrons (Hendel) (Diptera: Tephritidae) in Hawaii in March 2003. Over a three month period, eight releases, totaling 7,696 females and 3,968 males, were made in a turkeyberry, Solanum torvum Swartz (Solanales: Solanaceae) patch known to have a well established B. latifrons population. The estab...

Parasitoids display remarkable inter- and intraspecific variation in their reproductive and associated traits. Adaptive explanations have been proposed for many of the between-trait relationships. We present an overview of the current knowledge of parasitoid reproductive biology, focusing on egg production strategies in females, by placing parasitoid reproduction within physiological and ecolog...
