The oviposition of the chili fruit fly (Bactrocera latifrons Hendel) (Diptera: Tephritidae) with reference to reproductive capacity

Abstract

The chili fruit fly, Bactrocera latifrons Hendel, is a serious pest of chili fruit production in Thailand. To determine theeffective control planning of the fly population, the oviposition related to reproductive capacity of the female were observed.The female ovary was daily dissected through the entire life span and the eggs inside the ovary were examined and counted.There were 44.84±19.60 eggs/ovary. The oviposition of female was simultaneously conducted. Eggs inside the ovarypresented on 8th day and the female oviposited on 10th day of the life span. The female laid 4.25±2.28 eggs, which was 12.45±9.56 fold less than the reproductive capacity. The female longevity was 31.1±8.40 days and the oviposition period was 40days.
