Low density polyethylene (LDPE) banana bunch covers (bags) impregnated with chlorpyrifos were compared against standard untreated LDPE bags and bunch applications of either DDT-BHC dust and diazinon or chlorpyrifos sprays to control fruit damage by Chaetanaphothrips signipennis (Bagnall). Treated bags were a consistently effective treatment similar to dusting or spraying. One dieldrin spray before application of the untreated LDPE bags did not improve control. Untreated LDPE bags were partly effective and reduced the severity of thrips damage. Diazinon and chlorpyrifos bunch sprays provided equal control but high volume spraying of chlorphyifos caused severe phytotoxity to young fruit.
