The Oriental fruit fly, Bactrocera dorsalis (Hendel) is here reported to infest apple, apricot, nectarine, pear, peach and quince fruits from the Kashmir valley. Infestation to quince plants (Cydonia oblonga) constitutes a new global host record and to apple perhaps only the fifth known field infestation to be reported. The host suitability of the species on apple and quince was confirmed with harvested fruits, under cage rearing experiments. In field orchards, the fruit fly infestation for stated crops revealed a cumulative incidence and severity percentages of 17.33% and 6.44% respectively. All the specimens collected across different crops showed consistent morphological characters and were identified as one species. However, in light of the economic importance of the species, morphological studies were also integrated with molecular analysis for accurate identification of the species. The morphological characters and sequence results of amplified product of ITS1 and COX1 gene confirmed occurrence of single fruit fly species as B. dorsalis. Simulated future predictions along with notes on biology of the pest are discussed in light of the available literature. The future prospects regarding studies on population dynamics, host preferential selection, temperature dependency etc. will require a comprehensive understanding from the region.

来自克什米尔山谷（印度）的 Bactrocera dorsalis (Hendel) 的形态分子鉴定和新宿主报告

据报道，东方果蝇 Bactrocera dorsalis (Hendel) 会侵扰克什米尔山谷的苹果、杏、油桃、梨、桃和木瓜果实。对木瓜植物（Cydonia oblonga）的侵染构成了一个新的全球寄主记录，而对苹果的侵染可能只是已报告的第五个已知的田间侵染。在笼养实验下，用收获的果实证实了该物种对苹果和木瓜的寄主适应性。在大田果园中，所述作物的果蝇侵染显示累积发生率和严重程度百分比分别为 17.33% 和 6.44%。在不同作物中收集的所有标本都显示出一致的形态特征，并被确定为一个物种。然而，鉴于该物种的经济重要性，形态学研究还与分子分析相结合，以准确识别物种。ITS1 和COX1 基因扩增产物的形态特征和序列结果证实了单果蝇物种为B. dorsalis。根据现有文献讨论了模拟的未来预测以及有关害虫生物学的说明。关于种群动态、宿主优先选择、温度依赖性等研究的未来前景将需要对该地区的全面了解。根据现有文献讨论了模拟的未来预测以及有关害虫生物学的说明。关于种群动态、宿主优先选择、温度依赖性等研究的未来前景将需要对该地区的全面了解。根据现有文献讨论了模拟的未来预测以及有关害虫生物学的说明。关于种群动态、宿主优先选择、温度依赖性等研究的未来前景将需要对该地区的全面了解。
