Experiments were carried out against the red palm weevil, Rhynchophorus ferrugineus (Oliv.) (RPW in a private orchard containing varieties of Samani (domestic) and Ikhlas (imported) infested with weevil (RPW) El-Marg area, Cairo Governorate, Egypt, using Petroleum oil, Jojoba Inorganic salts, singly mixed each insecticides (Acetamiprid, Profenofos, Dimethoate) by injection spraying trunks, as w...

Laboratory bioassays were carried out with four neonicotinoid insecticides on multiple strains of Bemisia tabaci (Gennadius) to evaluate resistance and cross-resistance patterns. Three imidacloprid-resistant strains and field populations from three different locations in the southwestern USA were compared in systemic uptake bioassays with acetamiprid, dinotefuran, imidacloprid and thiamethoxam....

cotton aphid, aphis frangulae gossypii glover, is a major pest of cucumber in iran. one of the important parasitoids playing role in population control of this pest in the fields and greenhouses is lysiphlebus fabarum marshall. in this study, we investigated sensitivity of different instars of cotton aphids and pupal stage of l. fabarum to field recommended and half-recommended concentration of...

In this study, the development of imidacloprid and acetamiprid resistance in Myzus persicae populations relationship between neonicotinoid esterase enzyme were investigated seven which is collected from greenhouse pepper production areas 2018. order to determine ratios aphid against insecticides, 1 control 6 doses used. Each insecticide dose was used 3 replicates 25 adult female individuals eac...

1. Levels of azinphosmethyl (Guthion) resistance were low to moderate in codling moth populations throughout the state. 2. Populations high enough to screen against multiple chemistries had only low levels of resistance, preventing meaningful cross-resistance data for pyrethroids or chlorpyrifos (Lorsban). 3. A population with high azinphosmethyl resistance was identified near Manson during sec...
