To enhance biological control of insect pests in greenhouses, facilities and procedures for mass production of the parasitoids, Eretmocerus sp., Encarsia formosa, and Trichogramma brassicae, and the predator, Aphidoletes aphidimyza were successfully developed in Hengshui, Hebei province, China. Mass production of the aphelinid wasps was achieved by using different plant varieties and host insec...

The effectiveness of inundative releases of the parasitoid Eretmocerus eremicus n. sp. Rose & Zolnerowich for control of Bemisia argentifolii Bellows & Perring on poinsettia in replicated experimental greenhouses was determined. We evaluated two release rates of E. eremicus: a low release rate (one female per plant per week, released in two greenhouses, in spring 1995) and a high release rate (...

Intraguild predation (IGP) is pervasive in many managed and unmanaged ecosystems and may have negative, neutral or positive effects on the biological control of pest insects. Both generalist predators and aphelinid parasitoids attack Bemisia tabac i (Gennadius) Biotype B ( B. argentifolii Perring & Bellows) on cotton in the southwestern USA. Free-choice and no-choice laboratory assays were cond...

bemisia tabaci (gennadius) (hemiptera: aleyrodidae), is one of the most important pest of vegetable and fruit crops. this polyphagous pest has a range of natural enemies including the parasitoid eretmocerus mundus (merect) (hymenoptera: aphelinidae). to determine the molecular profile and taxonomic status of iranian isolates of e. mundus, parasitized b. tabaci samples were collected from cotton...

background identification of novel pathogenic bacteria always has a crucial role in clinical microbiology to defeat uncontrolled diseases. objectives sample preparation platform has been developed for rapid and simple detection of infectious organisms from the point of care diagnostics and molecular manipulation by using three novel genomic dna isolation protocols. materials and methods most of...
