Race Phytoseiulus Persimilis A.-H. (Acarina: Phytoseiidae)—Resistant to Organophosphorous Pesticides

How Does Phytoseiulus Persimilis Find Its Prey When Foraging within a Bean Plant?

The role of herbivore‐induced volatile substances in prey‐finding by phytoseiid mites has been repeatedly documented using an olfactometer. The objective of the present paper is to test the hypothesis that movement by Phytoseiulus persimilis is affected by these volatiles even on plants. Two series of laboratory experiments were carried out. In the first series we stud...

Neurobehavioural effects among workers occupationally exposed to organophosphorous pesticides.

AIMS To identify neurobehavioural deficits among workers exposed to organophosphorous (OP) pesticides in their occupation. METHODS This study was conducted during the period when pesticides were applied to cotton crops in the fields in Menoufiya Governorate, Egypt. Fifty two occupationally exposed male workers were compared to 50 unexposed male controls who were similar in age, socioeconomic ...
