江西樟树害虫的发生、危害特点与IPM策略

樟树是江西省省树,在全省范围推广种植多年,樟树虫害发生呈逐年上升趋势。据前期调查数据及文献资料,汇总统计江西樟树害虫179种,其中,重要害虫26种,占14.5%,次重要害虫23种,占12.8%,非重要害虫130种,占72.6%,包括重要食叶害虫樟叶蜂、泡桐叶甲、黄刺蛾、丽绿刺蛾、褐边绿刺蛾、樗蚕、龙眼裳卷蛾、樟巢丛螟等;重要刺吸性害虫六点始叶螨、樟脊网蝽、黑刺粉虱、樟木虱、樟白轮盾蚧、思茅壶蚧等;重要钻蛀性害虫家白蚁、黄翅大白蚁、黑翅土白蚁、吉安樟筒天牛等;重要地下害虫粉白金龟、黑绒金龟等。据危害方式、发生特点将其归为强生态适应性害虫、r类害虫、隐蔽性害虫与嗜食性害虫,由此有针对性地提出其IPM策略。

Occurring Characteristics and IPM Strategies for Camphor Tree Pests in Jiangxi Province

As a provincial tree, the camphor tree, Cinnamomum camphora （L.） Presl, has been planted throughout the Jiangxi Province for many years, and the trend of pests occurring in this kind of trees is rising. Based on the early data and literatures, this paper showed that there were totally 179 pest species occurring in camphor trees, including 26 species of key pests （accounted for 14.5%）, 23 species of sub-key pests （accounted for 12.8%）, and 130 species of non-key pests （accounted for 72.6%）. The key defoliators were Mesoneura rufonota, Cnidocampa flavescens, Latoia lepida, Latoia consocia, Philosamia Cynthia, Cerace stipatana, Orthaga olivacea and so on. The key sucking pests were Eotetrallychus sexmaculatus, Stephanitis macaona, Aleuyocanthus spini- ferus, Triozacam Phora, Aulacaspis yabunikkei, Cerococcus schimae and so on. The key borers were Coptotermes formosanus, Maerotermes barneyi, Odontotermes formosanus, Oberea jiana and so on. And the soil pests were Cyphochilus insullanus, Serica orientalis and so on. According to characteristics of pest damage and occurrence, the key pests were classified into four categories： highly-adaptable pests, r-pests, hidden pests and preferred-pests. Finally the IPM strategies were targeted to discuss.
