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...
Alternative food sources could sustain predator populations by influencing their performances including predation, development, and reproduction in periods of shortage or scarcity prey under laboratory fields conditions. The aim this study was to explore suitability cattail pollen (Typha orientalis) as an alternative source for different stages Amblyseius herbicolus (Chant) (Acari: Phytoseiidae...
The developmental progress of silverleaf whitefly (Bemisia argentifolii) 3rd instars and 4th instar/pharate adults was monitored using a tracking system that had been designed to identify synchronous individuals in another species of whitefly, the greenhouse whitefly, Trialeurodes vaporariorum. When reared on greenbean under conditions of LD 16:8 and a temperature of 26 +/- 2 degrees C, the bod...
The whiteflies Bemisia tabaci Gennadius and Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) are two of the main pests in tomato crops. Their biological control in Mediterranean IPM systems is based on the predators Macrolophus pygmaeus (Rambur) and Nesidiocoris tenuis Reuter (Hemiptera: Miridae), as well as on the parasitoids Eretmocerus mundus (Mercet) and Encarsia pergandiella H...
The capsid protein (CP) of the monopartite begomovirus Tomato yellow leaf curl Sardinia virus (TYLCSV), family Geminiviridae, is indispensable for plant infection and vector transmission. A region between amino acids 129 and 152 is critical for virion assembly and insect transmissibility. Two previously described mutants, one with a double Q129P Q134H mutation (PNHD) and another with a further ...
منظور بررسی مناسب بودن سنین مختلف trialeurodes vaporariorum westwood برای encarsia inaron walker مطالعاتی در آزمایشگاه انجام گردید. میزان پارازیتیسم، مرگ و میر، دوره رشد، نسبت جنسی و طول عمر پارازیتوئیدهای خارج شده از سنین مختلف مگس سفید گلخانه ثبت گردید e.inaron کلیه سنین را پارازیته نمود با این حال سن دوم لاروی بالاترین میزان (44%) و مرحله شفیرگی کمترین میزان پارازیتیسم (14%) را داشت. بالاتری...
