Characteristics and Control of a New Pest of Avicennia marina —Hyblaea Puera Cramer
摘要
Abstract
[Objective]Hy b laea puera is a new pest in Guangxi mangrove forest in recent years. In order to better protect mangroves,the biological characteristics of the insects and their con-trol methods are studied.[Method]The morphological characteristics of different stages of the pest,living habits and life history of the pest in Guangxi mangrove forest and its main natural enemies were observed.The causes of insect outbreak and its impact on mangrove ecosystems were analyzed and the light trap control test was carried out.[Results]The results showed that the larvae were significantly different in different age and different generations; the insect oviposition was up to 834 particles,with an aver-age of 477;the only insect feeding damage in the Mangrove Avicennia marina , mature larvae would use non host plant leaves to nest in pupa-tion.The insect in Guangxi coast occurred 11 generation,the different generations of pests transferred hazard between terrestrial vegetation and mangrove and different mangrove diversity;pest outbreaks would quickly eat up leaves and gnaw twigs and fruit skin,affect the growth of Avicennia marina ,a large number of excreta during feeding damage would cause soil acidification;the adults had strong phototaxis.[Con-clusion]In view of the great harm caused by insects on mangrove,it is necessary to carry out in-depth research,including its occurrence,monitoring and control measures;monitoring and control is a pressing matter of the moment on the shore of teak pests,to avoid pests spread to the mangrove area.关键词
