榴梿重要害虫——马来异裂木虱[Allocarsidara malayensis(Crawford)]在中国的发现及其潜在适生区预测
First Report of Allocarsidara malayensis(Crawford)in China,an Im-portant Durian Pest and Prediction of Potential Suitable Habitats
摘要
Abstract
This paper reported the detailed morphological characteristics and the external genitalia of Allocarsidara ma-layensis,the COI sequence of A.malayensis was amplified and sequenced,its damages characteristic in the field were provided and potential suitable habitats in China was predicted.Based on 25 effective distribution points and 19 climate environmental factors,maximum entropy niche-based modeling(MaxEnt)combined with geographic information sys-tem(ArcGIS)was used to predict the potential suitable habitats for A.malayensis under historic climatic conditions.ROC curve analysis method was used to validate,knife-edge method was used to analyze the major environmental variables influencing the distribution of the A.malayensis.The potential suitable habitats of A.malayensis was mainly in the tropical areas near the equator of Southeast Asia,South Asia,Africa,South America and North America.In China,there was potential suitable habitats in Hainan,Guangxi,Guangdong,Fujian,Taiwan,Yunnan,Sichuan and Guizhou provinces for A.malayensis.The key environmental variables that had the greatest impact on the potential suitable habitats of A.malayensis were the precipitation of wettest month(Bio13)and precipitation of wettest quarter(Bio16).The investigation showed that A.malayensis had occurred in some durian gardens in Sanya and Baoting of Hainan,and the damage was serious in some of the gardens.The adults lay eggs in the unopened leaves at the shoot apex,and both adults and nymphs pierce the young leaf and suck the cell sap,that may cause leaves twisting,discoloration and small.Both adults and nymphs secrete honeydew,which induces sooty mould and reduces the photosynthesis.If no control measure applied,severe infestation may cause leaves drop in advance,stunted growth or even cause tree death.As the potential suitable habitats of A.malayensis was almost consistent with the durian planted region,in order to prevent the pest further spread to other regions,provide guarantee for the healthy development of durian industry in China,it is recommended to strengthen the monitoring of A.malayensis,study its biological characteristics and the population dy-namics,which would provide a theoretical basis for further development of economical and efficient control strategy for A.malayensis.关键词
