| 摘 要： | 测定了龙眼幼果期荔枝蝽(TessaratomapapilosaDrury)若虫密度与落果率的相关性及防治指标。结果表明,龙眼幼果期幼龄树及成龄树2龄若虫密度防治指标分别为1.6头/果穗和1.2头/果穗,而相应的有虫果穗率分别为33%和26%。同时,根据福建龙眼生产的实际情况,制定了不同产量、价格相应的虫口密度及有虫果穗率的防治指标,为防治提供理论依据。 |

| Abstract: | The correlation between the density of nymph of litchi stink bug (Tessaratoma papilosa Drury) and the fruit drop rate of longan (Euphoria longan), and the economic threshold for its control were determined during the young fruit period of longan. The results indicated that the economic threshold for density of the 2 instar nymph of the stink bug in young plants and adult plants were 1.6 and 1.2 heads/panicle respectively, while correspondently 33 % and 26 % of panicles were found to have the bug in young and adult plants. Meanwhile, the economic threshold for the nymph density and the rate of bug-infested panicles was also put forward for the bug control based on fruit yield and prices. |
