| 摘 要： | 危害橄榄果实的杧果小齿螟以幼虫蛀食橄榄果实，受害林分虫株率达10％～100％，单株果实受害率5％～60％。该虫在福建平和1年发生3代，以老熟幼虫或蛹在枯枝、朽木或树干裂缝内越冬，5月上旬成虫开始羽化，经1～3d后交配产卵，卵产于两果之间靠接处，卵期6～8d。幼虫每年5月下旬至6月下旬，7月下旬至8月下旬有2个危害高峰期；老熟幼虫爬出蛀果在枯枝或朽木中化蛹，蛹期13—21d。该虫危害下坡比上坡重，不同品种之间大红心受害较重。清除树上、园中枯枝朽木，能显著减少虫口密度，可有效降低受害率。 |

| Abstract: | Pseudonoorda minor, one of the main fruit pests damaging to Canarium album, which harms the fruits by its larvae, the infestation rate was 10% - 100% among the plants and 5% - 60% among the fruits. It was observed that P. minor occurred three generations each year in Pinghe County, Fujian Province, which overwintered as adult, larva or pupa inside deadwood, rotten wood or bough cracks of the trunk. The adults began to emerge in early May, and started to oviposit in the joint portion among the fruits 1 - 3 days after emergence, the oviposition lasted for 6 - 8 days. The damage of P. minor larvae to C. album trees concentrated in two periods of time, i, e. , from late May to late June, from late July to late August each year. The mature larvae crawled out of the damaged fruits and pupated in the dead branches or rotten wood, the pupa period lasted for 13 -21 days. Geographically, it was found out that P. minor occurred more seriously to the C. album trees growing in the downhill area than those growing in the uphill area. There was also difference in the damage among cultivars of the C. album trees, the scarlet variety suffered more seriously than the others. The study showed that clearing out the dead branches from the trees and rotten wood from the orchard could significantly reduce the pest population density so as to reduce the infestation rate. |
