Abstract
Abstract:
The present work was conducted to evaluate the efficiency of two mineral oils,[capl-2 and kemesol], two organophosphorus insecticides, [malathion (Malathaite) and prothiofos  sulfur product [Cabritol] and their binary mixtures on the most serious scale insects attacking guava trees, Pulvinaria psidii (Mask) (Homoptera: Coccidae) and Planococcus citri (Risso.) (Homoptera: Pseudococcidae). The effects of these chemicals against two associated predators, Amblyscius gossipii (El-Badry) and Tydues californicus (Banks) were also investigated. The mixture of kemesol with malathion was the most effective treatment on P.psidii followed by capl-2, kemesot, mixture of capl-2 with malathion, mixture of capl-2 with cabritol, malathion and finally prothiofos. There were no significant differences between the effect of the two mineral oils and their mixtures with malathion on the reduction percentage of P. psidii. On the other hand, kemesol was the most effective compound on P. cirri followed by prothiofös, mixture of kemesol with malathion whereas capl-2 was the least effective on P.citri. There were no significant differences among the tested compounds. The mixture of capl-2 and cabritol caused the least population reduction (39.1%) on Amblyscius gossipii (El-Badry) while mixture of kemesol with malathion caused the highest population reduction (58.5%). The data on Tydues californicus (Banks) revealed that the mixture of capl-2 with cabritol caused the least population reduction (58.0%). So, mineral oils alone are preferable against both P.psidii and P.citri. Also, mixture of capl-2 and cabritol could be recommended against P.psidii because of its minimum effect on the associated predators.
