Rice is an important cereal crop and is cultivated virtually in all agro-ecological zones in Tanzania. However, production capacity is far below the national requirement. One of the major reasons for the low yields of rice in Tanzania is damage by insect pests, particularly rice stem borers. Four rice stem borer species reported to infest rice crop in Tanzania includes the white stem borer, Maliarpha seperatella Ragonot, African pink borer, Sesamia calamistis Hamson, spotted stem borer, Chilo partellus Swinhoe and stalk-eyed fly, Diopsis thoracica Westwood. Inappropriately, the potential for proper management of these stem borers to enhance yield has not been fully realized due to limited information available for the respective stem borer species. Proper management of rice stem borers, therefore, is a pre-requisite for enhanced and sustainable rice production among smallholder farmers that epitomize the rice production industry in Tanzania. In this review, rice stem borers were reviewed with emphasis on occurrence and distribution, nature of damage, biology and life cycle, host plant and management options.

坦桑尼亚的水稻螟虫种类:综述

水稻是一种重要的谷类作物,几乎在坦桑尼亚的所有农业生态区都有种植。但产能远远低于国家要求。坦桑尼亚水稻产量低的主要原因之一是虫害,特别是水稻螟虫的破坏。据报道,坦桑尼亚有四种水稻螟虫侵染水稻作物,包括白螟、Maliarpha seperatella Ragonot、非洲粉螟、Sesamia calamistis Hamson、斑点螟、Chilo partellus Swinhoe 和茎眼蝇、Diopsis thoracica Westwood。不恰当地,由于可用于相应茎螟物种的信息有限,尚未完全实现对这些螟虫进行适当管理以提高产量的潜力。因此,正确管理水稻螟虫,是在坦桑尼亚大米生产行业的缩影小农中加强和可持续大米生产的先决条件。在这次审查中,对水稻螟虫进行了审查,重点是发生和分布、损害性质、生物学和生命周期、寄主植物和管理选择。
