Resistance to deltamethrin and fenitrothion in dubas bug, Ommatissus lybicus de Bergevin (Homoptera: Tropiduchidae) and possible biochemical mechanisms.

Environmental pollution, ill-effects on human health, insecticide resistance development and insect pest resurgence are some serious problems that may arise due to excessive chemical spraying for pest control. Despite of heavy aerial and surface insecticide spraying, incomplete control of Ommatissus lybicus de Bergevin 1930 (Homoptera: Tropiduchidae) is reported in Oman every year, which requires investigation of insecticides resistance in pest. Fifteen populations of O.

Susceptibility survey of Ommatissus lybicus (de Bergevin) populations against deltamethrin and fenitrothion in Oman.

Despite of extensive application of insecticides, severe infestation of date palms is reported with Ommatissus lybicus every year. The development of insecticide resistance in the field strains receiving heavy pesticide regimes can be a reason for unsuccessful control. Seventeen field strains of O.
