太阳能自控多方式诱虫灯对槟榔害虫的诱捕效果评价

本研究对太阳能自控多方式诱虫灯诱捕槟榔害虫的效果进行了评价。结果表明,经过240 d,诱虫灯共诱捕害虫255 924头,共计8个目、26科、46种昆虫,其中鳞翅目害虫达到64.33%;诱虫灯诱虫数量、重量在8—11月增加,12—2月减少,3月后再增加,其诱虫数量变化与当地虫害发生规律相一致,且益虫仅占总虫量的0.80%;灯控区槟榔受虫害等级比非灯控区少1~3个等级,虫害发生等级控制在++以内。灯控区坐果率在开花结果初期、收获期明显高于非灯控区,明显降低落果率,单株产量达到10.96 kg,比非灯控区提高36.61%。因此,该型诱虫灯在槟榔园使用具有诱虫谱广,诱杀作用强的特点,可大幅减少虫害发生,提高坐果率,增加产量。

Application Effect Evaluation of Solar Energy Self-Controlled Multifunctional Pest Trap Lamp on Areca catechu L.

The effect of solar energy self-control multi-function and multi-mode trap lamp trapping pest on Areca catechu L. was studied. A total of 255 924 pests in 8 orders, 26 families and 46 species in 240 days were trapped, among which the number and weight of Lepidoptera pests reached 64.33%. The number and weight of trap lamp increased from August to November, decreased from December to February, and increased after March. The change of trap number was consistent with the occurrence law of local pests, and the beneficial insects accounted for only 0.80% of total pests. The pest grade of Areca catechu L. in the control area of trap lamp was less than that of the non-trap lamp by 1-3 grades, and the occurrence level of insect pests was less than ++. The fruit setting rate in the control area of trap lamp was significantly higher than that in the area without trap lamp at the beginning of flowering and fruiting. The fruit falling rate was significantly reduced, which made the yield of trap lamp reach 10.96 kg per plant, 36.61% higher than that of the area without trap lamp. The results showed that the trap had a wide spectrum of insect traps and strong trapping effect. It could reduce the occurrence of insect pests, increase fruit setting rate and increase yield when it is used in A. catechu L. orchard.
