Comparison of susceptibility of geocoris punctipes and lygus lineolaris to insecticides for control of the tarnished plant bug

Informally Refereed

Abstract

Comparison of the susceptibility of Geocorispunctipes (Say) and the tarnished plant bug (TPB), Lygus lineolaris (Palisot de Beauvois) to selected insecticides was determined in topical, tarsal contact, and field studies. In both topical and tarsal contact studies, L. lineolaris was more susceptible to imidacloprid and oxamyl residues than G, punctipes. However, oxamyl was more toxic to the pest than imidacloprid. Both insect species responded very similarly to fipronil, acephate, dicrotophos, and lambda-cyhalothrin, all of which were very toxic to these insects. In our field study, lambda-cyhalothrin had an equally negative impact on populations of TPB and G. punctipes concurring with previously published field studies. Results from our laboratory and other field studies indicate that oxamyl and imidacloprid would be effective against TPB while conserving populations of G. punctipes for biological control of lepidopteran larvae in cotton.
