Effects of host fruit and larval density on development and survival of Bactocera sp. (Malaysian B). (Diptera : Tephritidae)

Chua Tock Hing, . Effects of host fruit and larval density on development and survival of Bactocera sp. (Malaysian B). (Diptera : Tephritidae). pp. 277-280. ISSN 0126-6128

The effects of five fruits (guava mango papaya strarfruit and tomato) on the larval survival adult eclosion and size of ((Bactovera)) sp. (Malaysia B) were investigated. The percentage pupation and adult emergence from pupae were not affected by different hosts except for guava which gave the lowest percentage of adult emergence. Papaya and mango yielded the largest adult (2mm head width). Comparison of composition of fruits indicated that a high percentage of carbohydrate and high pH in fruits would produce larger adults. High larval density reduced the percentage of larval survival adult emergence and adult size.

Abstract

The effects of five fruits (guava mango papaya strarfruit and tomato) on the larval survival adult eclosion and size of ((Bactovera)) sp. (Malaysia B) were investigated. The percentage pupation and adult emergence from pupae were not affected by different hosts except for guava which gave the lowest percentage of adult emergence. Papaya and mango yielded the largest adult (2mm head width). Comparison of composition of fruits indicated that a high percentage of carbohydrate and high pH in fruits would produce larger adults. High larval density reduced the percentage of larval survival adult emergence and adult size.
