Studies On Occurrence And Control Technique Of The Major Pests On Honeysuckle In Hanzhong Area

Honeysuckle (Lonicera japonica Thunb.), also known as Rendong, double flowers, Silver Flower, is a perennial evergreen rattan of Lonicera of Caprifoliaceae, is commonly used in traditional Chinese medicine with its dry flower bud or primal flower and rattan.This article regard important traditional Chinese medicine honeysuckle (Lonicera japonica Thunb.) in Hanzhong as the research object, based on GAP of traditional Chinese medicine, set up environment-friendly honeysuckle and standardization production technology system. Investigated the number of the major pests and natural enemies on honeysuckle in Hanzhong, found out the major pests annual growth and population dynamics, selected the different environment-friendly pesticides witch suit for the honeysuckle growing and pests, provided the basis for GAP of honeysuckle in Hanzhong area. The result shown:1. Investigated the community of arthropod in honeysuckle field in Hanzhong. The community of arthropod in honeysuckle field is composed of 2 classes, 12 orders, 49 families, 94 species. There are 18 species common pests on honeysuckle. Aphid, Heterolocha jinyinhuaphaga Chu and Haemorrhagia staudingeri staudingeri (Leech) are the major pests and the ladybird beetle and spider is the major natural enemy.2. Found the population dynamics of the major pests and natural enemies in honeysuckle field. Aphid has occurred seriously in April and May, at the end of April to the beginning of May for the peak which occurred. H. jinyinhuaphaga occurred seriously from May to September. There appears 4 peak times, witch basically tally with the honeysuckle flower bud times. The larva of H. staudingeri occurs seriously from May to September, appears 3 peak times, witch are in late May, in middle and last ten days of July, and in first and middle ten days of September.3. The population dynamics of the ladybird beetle and spider were investigated on honeysuckle. The results of correlation analyses showed that they were closely related to the population number dynamic of aphid. But there was a time lag between the aphids and the natural enemies, which was a distinct following phenomenon.4. The environment-friendly insecticides efficacy experiment of the major pests in the field showed that the control efficiencies of Difluron, BT, Abamectin and QCK were more than 90%.
