| Experiment Background | Spine gourd (Momordica dioica Roxb. Ex Willd.) is a vine vegetable crop belonging to the family Cucurbitaceae which originated from the Indo-Malayan region. It is largely cultivated in tribal regions. It is distributed in Bangladesh, China, India, Malaysia, Nepal, Myanmar, Pakistan, and Sri Lanka. In India, this vine vegetable is mainly cultivated in West Bengal, Gujarat, Madhya Pradesh, Maharashtra and Karnataka. Besides, spine gourd grows naturally in the forest areas of Chhattisgarh, Jharkhand and odisha where it is regularly consumed by the native tribals (Kushwaha et al., 2005). Spine gourd is an economically important vine vegetable crop with high food and medicinal value. It is cultivated for its fruits, which used as vegetable. It is known as Kakrol, Kartoli and Kankoda, Teasel gourd or Bhat Kerala. As per nutritional point of view, the fruits of spine guard contain 84.10 per cent moisture, 7.70 g carbohydrate, 3.10 g protein, 3.10 g fat, 3.00 g fiber and 1.10 g minerals (Kushwaha et al., 2005). The small quantities of essential vitamins like ascorbic acid, carotene, thiamin, riboflavin and niacin are also found in its fruits. The different biotic and abiotic factors responsible for reducing the yield of the spine gourd. Now a days spine gourd has been subjected to damage by various insect pest viz., green stink bug, skin feeder, fruit borer, epilachna beetle, red pumpkin beetle, leaf miner and fruit fly that cause varying degrees of damage, that limiting the production and productivity of the crop (Shaw et al., 1998). Among them, fruit fly, Zeugodacus duplicatus (Bezzi) is an economically important pest of spine gourd as the maggots feed inside male flowers which leads to rotting and ultimately dropping of the flowers. The fruit setting is affected as fly damaged to the male flowers which affects the pollination. Many natural enemies that are responsible for regulating populations, either naturally or by means of augmentative releases, have been identified. The fruit flies are being attacked by more than dozen species of natural enemies and playing an important role in the regulation of pest population which can be exploited to the maximum possible extent in the management of fruit flies. The majority of fruit fly natural enemies in the India belong to the families Braconidae. During the year 2024-25 we carried intensive rapid roving survey and collected various fruit fly infested cucurbitaceous fruits. The results revealed that Zeugodacus duplicatus (Bezzi) was parasitized by Psyttalia fletcheri (Silvestri) in spine gourd. The present investigation will be carried out to know the status of Z. duplicatus and its parasitism by P. fletcheri in spine gourd under south Gujarat. | ||
