1. Virgin production of female offspring in a usually arrhenotokous wasp, spaqlangia endius walker (hymenoptera: pteromalidae)

Abstract
Spalagia endius , a parasitod of house fly puparia, is usually arrhenotokous. We report results which demonstrate that some virgin females also produce female offspring. The limited evidence available suggests this ability is not transmitted to subsequent generations.

Abstract
A Pictorial key to 15 pest species of the dacine fruit flies associated with cultivated plants in Sri Lanka is given. The species included are as follows ; Bactrocera caryeae B. caudate, B. correcta, B. cucurbitae, B. diversa, B. dorsalis, B. kandiesis, B. latifrans,B. trilineata B. versicolor , B verbascifoliae, B. zonata, B. sp near tau, Dacus ciliatus and D. discophorus. B. dorsalis, B. kandiensis, and B. cucurbitae are serious pest species in Sri Lanka.

Abstract
Host plants including a total of 22 families representing 45 species were recorded for 16 fruit flies of the tribe dacini in Sri Lanka. Bactrocera kandiensis was found to be highly polyphagous, and its host range was as wide as that of B. dorsalis Some host plants of B. dorsalis, B.kandiensis, B. correcta, B cucurbitae, and B. trilineata were newly recorded. In addition, host plants of B. gavisa, B. sp near nigrotibialis, B sp. near tau, Dacus discophorus, and D. keiseri were recorded for the first time . Host plants of 46% Sri Lankan Dacini are now Known. Key words: Biology, Diptera , fruit flies, Dacini, host plants, Sri Lanka.
