Mexican bean beetles are highly devastating pests that attack bean plants - as the name suggests - and more. They feast on plants and are capable of causing huge damage, wrecking any potential crop. But what are they, and how can you control Mexican bean beetles? They are distinctive beetles...
Mexican bean beetles (egg masses, larvae, and adults) were counted on 3 occasions: the first 2, entire plants were examined; on the third, 10 trifoliate leaves were examined. Plots were harvested by hand on September 17 (15 row feet per repl), shelled, and weighed.Alan C. York...

Tests showed that the residual, wash-off-resistant carbaryl formulations Sevin XLR and UCSF-27 provided control of adult beetles from 14 to 21 days posttreatment. In order of decreasing duration of effectiveness, those two formulations were followed by acephate, permethrin, and cypermethrin, which ...
The blood of the Mexican bean beetle (Epilachna varivestis) contains a homotropane alkaloid, euphococcinine (1). The beetles 'reflex bleed' when disturbed, thereby deploying the alkaloid, which is provenly deterrent to spiders and ants. Newly emerged adults lack the alkaloid, but the compound...

The infestation of Mexican bean beetles averaged 10-15 adults/6 ft of row. Treatment plots were 10 脳 20 ft, replicated 3 times, and arranged in a randomized complete block design. Sprays were applied by CO2 backpack sprayer calibrated to deliver 20 gal/acre at 40 psi. Posttreatment counts...
