Abstract:New and standard insecticides, applied as sprays to the foliage of red kidney beans, were evaluated for control of t he Mexican bean beetle, Epilachna varivestis Mulsant, in 1966 and 1967. Of 29 materials tested, only 2 failed to give satisfactory control of the beetle.
In 1968 granular formulations of 2 systemic insecticides, phorate (1O%G) and disulfoton (1O%G) , applied on top of snap beans at planting time gave good control of Mexican bean beetle.
Significantly fewer plant bug nymphs (Lygus lineolaris (Palisot de Beauvais) and poecilocapsus lineatus (F.)) were taken from treated plots of alfalfa than from control plots when 13 insecticides were applied as sprays in 1966. It was concluded that adult plant bugs and potato leafhoppers, Empoasca fabae (Harris), which were included in the sampling operation of this experiment, were not reliable indicators of insecticidal efficacy because of their high rate of activity and the ensuing possibility of migration from plot to plot.
In 1968, 1O to 21 insecticides applied as foliar sprays to plots of red kidney beans were found to control the potato leafhopper effectively, judged from nymphal counts taken in treatment and control plots.
