Japanese beetles were first detected in northwest Arkansas in 1997 and increased to economic importance by 2002. Significant differences in foliar damage among many different fruit genotypes were recorded at the University of Arkansas Agricultural Experiment Station Farm in Fayetteville, Arkansas. Preliminary laboratory results are presented on adult and larval mortality after adult males and females were contaminated with a mixture of Milky Spore bacteria, Bacillus popillae, and entostat powder using an autodissemination trap with a bacteria contamination chamber.
