摘要:

荔枝蝽Tessaratoma papillosa是荔枝和龙眼生产中的重要害虫,在中国南方及东南亚地区危害严重。该虫以若虫及成虫吸食寄主植物的嫩芽、嫩梢、花穗和幼果,成虫和3龄以上若虫是传播龙眼鬼帚病病原体的传病介体昆虫。本文综述了近60年来国内荔枝蝽的研究情况,旨在为广大科研工作者提供更详尽的荔枝蝽研究现状,以期为该虫的深入研究及绿色防控技术的研发提供参考。荔枝蝽为不完全变态昆虫,一年发生1代,若虫期80 d左右,成虫寿命为203~371 d,单雌产卵总量190粒左右,在习性上表现出明显的聚集性、趋光性、趋色性和趋嫩梢性。近年来,通过荔枝蝽触角感受器分类及分布观察,触角转录组数据测定和分析,臭腺解剖观察以及臭腺分泌物组分分析,对该虫触角和臭腺两大器官组织已有较深入研究及了解。目前,荔枝蝽的发生期主要通过卵巢发育分级法进行预测预报,对该虫的防治仍然是以化学防治为主,农业防治、物理防治和生物防治为辅的策略。其中,荔枝蝽生物防控技术研究报道最多,主要集中在天敌的保护利用和生物源农药的应用。由于荔枝蝽虫源的季节性制约和发生为害地域限制,对该虫的研究进展缓慢,深层次的研究较少,且所涉及到的研究领域也比较窄。从组学、分子生物学、细胞生物学等多角度探明荔枝蝽对寄主植物的选择机制,与寄主植物、天敌及共生菌间的互作关系,以及抗药性机理等,将为荔枝蝽绿色防治技术带来新思路。

Abstract:

 Litchi stink bug, Tessaratoma papillosa (Hemiptera: Pentatomidae), is one of the most widespread and destructive pest species on litchi (Litchi chinensis) and longan (Euphoria longan) in South China and Southeast Asia. T. papillosa feeds on the buds, tender branchlets, flowers, and fruits of host plants. Furthermore, the nymph over the 3rd instar and adult of T. papillosa are the vectors of witches’ broom pathogen on longan tree. In this article, we provide a detailed review on T. papillosa based on the research over the past 60 years in China, in order to provide references for the further study and development of green control technology of this pest species. T. papillosa is a hemimetabola insect which occurs one generation a year. Its nymphal duration and adult longevity are about 80 d and 203-371 d, respectively. Moreover, averagely one female adult of T. papillosa can deposit 190 eggs in its lifetime. Regarding the life habits, T. papillosa has the aggregation behavior, possesses phototaxis and chromatics tropism, and prefers tender branchlets. By the classification and distribution observation of antennal sensilla, RNA-seq analysis of antennae, dissection and observation of scent gland and comparative analysis of secretary components from scent gland, the two organs of antennae and scent gland of T. papillosa have been more deeply studied and understood. To date, the occurrence of T. papillosa is mainly forecasted through its ovarian development of female adults. Together with the pest forecasting technology, management of T. papillosa mainly depends on chemical control, supplemented by cultural, physical and biological control measures so far. The biological control technology has been reported the most, with aspects of the protection and utilization of natural enemies and the utilization of botanic pesticide. Owing to the seasonal restriction of experimental insect source and geographical limitation of infestation, the research progress of T. papillosa is relatively slow, the in-depth studies are limited and the research fields are relatively narrow. In future study, we can explore the selection mechanism of host plants, the interaction among host plants, natural enemies and symbiotic bacteria, and pesticide resistance from the perspectives of omics, molecular biology, cell biology and other aspects, to provide new clues for green pest control technology of T. papillosa.
