In greenhouse experiments it was found that pepper transplants which had nymph and adult tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois), confined to them showed a significant increase in the drop of buds and blossoms over control plants the same age.

Subsequent field experiments, in 2 widely separated areas of Delaware, corroborated the initial laboratory evidence. In caged treatments where no tarnished plant bugs were introduced, or in treatments where a systemic insecticide was applied to the soil as a granular subsurface application and adult tarnished plant bugs were subsequently added, a significantly larger number of buds, blossoms. and fruit resulted when compared with caged pepper plants to which adult bugs had been introduced and no control measures were taken.
