| 摘 要： | 荔枝蝽象是华南地区的重要害虫之一。作者根据此虫自然抗药性季节变化的規律,結合荔枝的开花結果时期,采用有机磷杀虫剂敌百虫0.067％水溶液噴雾于3月中及5月初各噴药一次,防治效果达95％以上。基本可以消灭荔枝蝽象成虫及若虫的为害,达到保花保果的要求。根据試驗結果,掌握上述两个时期大面积噴敌百虫,对荔枝开花、結果以及品质,均无不良影响。噴药时最好暫时关閉蜂箱,噴药后再放蜂。大面积使用敌百虫防治荔枝蝽象,成本低廉,每株药剂及人工費用为0.177元,每亩15株計算,每亩費用为2.65元。防治时期,最好选择能在3—4天內天晴、气温较高、风力0—1級为宜,噴雾要求均匀周到。

| Abstract: | The Lichee stinkbug is a very serious pest of the famous fruit-trees Lichee (Lichi chinensis Sonn.) and Lungyan (Euphorbia longan Lam.) in south China. No effective method of control was found until it was discovered some four years ago that Dipterex (trichlorophon) is very toxic against this pest. Dipterex was found to be one of the most effective of the 20 compounds tested in the field for the control of this pest. As the susceptibility of this insect against Dipterex changes throughout the year and it is very necessary to protect the Lichee flowers and the young fruits from the injury, proper timing of spray application is very important for effective control. In the spring of 1963 a large-scale field experiment was carried out in a people''s commune in the vicinity of Canton. Results of a series of experiments indicated that Dipterex at a concentration of 0.067% was very effective in killing the adults and young nymphs (average mortality above 95%) when applied in the middle of March and at the beginning of May for twice respectively. This is the period when the susceptibility of the insect to the insecticide is very low as indicated by the low fat content and other physiological conditions. This method of control would not seriously affect the aetivities of the egg-parasites of the pest, offers no contradiction with bee-keeping and the flavour and quality of Lichce fruits are not affected. |
