Efficacy of abamectin and thiamethoxam mixture against Bemisia tabaci in tomato and toxicity on male albino rats

Abstract

There are many benefits to mixing pesticides including controlling a broad spectrum of pest species and overcoming the phenomenon of insect resistance to the action of pesticides. Two field experiments were conducted during the 2019 and 2020 seasons, at Alwakeel village, El-Beheira Governorate, Egypt to investigate the efficacy of abamectin and thiamethoxam mixture (AB+THIA) against the whitefly, Bemisia tabaci. The mixture gave a high reduction of whiteflies, where the general means of initial and residual reduction percentage of adult stages were 83.

Evaluating the toxic efficacy of some bio-insecticides against mature stages of whitefly insect (Bemisia tabaci).

“…The results are shown in Table (2). There are significant variances in the impact of durations in nymphs population density its lowest after 7 day of spraying bio-pesticide which reached 13.77 nymphs/16 cm 2 , which differed significantly from the duration after (1,3), which amounted to (17.36 and 15.21) nymphs/16 cm 2 , respectively.…”

“…The whitefly Gennadius (Bemisia tabaci) of the order Hemiptera and the Aleyrodidae family are insect pests widespread in most parts of the world. (America, Europe, Africa, Asia, then Australia) has a wide plant hosts range and causes harm and threat to most economic crops due to its direct and indirect damages, as this insect has the ability to transmission of more than 110 plant pathogenic viruses (1,2).This insect infects a wide range of plant families , among the plants most susceptible to infection with this insect are tomatoes, cucumbers, okra, cotton and eggplant (3,4,5,6,7,8,9).…”
