Issue Date

10-2012

Abstract

Seven (7) varieties of hot pepper (Capsicum frutescens L) were evaluated for resistance/susceptibility to insect pests and disease at the Regional Apiculture Center, CBSUA from November 2011 to February 2012. Analysis of data used RCBD and means compared using DMRT. All the hot pepper varieties were infested with 11 species of insect pests and infected with four (4) disease during the vegetative, flowering and reproductive stages. Three (3) natural enemies were found associated with the insect pests. Aphid colonies were found at the different growth stages of hot pepper with peak population during the vegetative stage. Damage assessment for leaf cutting and sucking insects showed that all the varieties were resistant. Similarly, all varieties were resistant to bacterial wilt, anthracnose, leaf spot and leaf curl diseases. There were significant differences in agronomic characteristics and marketable yield among the varieties evaluated.
