Evaluation of Twelve Genotypes of Hibiscus for Resistance to Hibiscus Sawfly, Atomacera decepta Rohwer (Hymenoptera: Argidae)

Abstract

Twelve genotypes of hibiscus were evaluated for resistance to hibiscus sawfly, a minor pest of hibiscus. Evaluations were conducted by counting eggs deposited on the hibiscus and larvae feeding on the hibiscus. Plants were evaluated at the end of the study with a damage rating. Three genotypes demonstrated resistance or tolerance to sawfly feeding: Hibiscus acetosella , H. aculeatus , and H. grandiflora . All three of these genotypes had few, if any, eggs or larvae and were given the lowest damage rating among the genotypes evaluated.
