摘  要：本研究對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。

Abstract： The effect of solar energy self-control multi-function and multi-mode trap lamp trapping pest onAreca 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 ofAreca catechuL. 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 inA. catechuL. orchard.

槟榔（Areca catechuL.）是单子叶植物纲、初生目、棕榈科常绿乔木，属于“四大南药”之首^[1]，在我国分布于海南、台湾、云南、广西、广东和福建等地。槟榔是海南省重要经济作物之一，种植面积广泛。但海南特殊的气候条件，致使槟榔虫害发生代数多，危害严重。例如，椰心叶甲于2002年入侵海南以来迅速蔓延，为害槟榔幼嫩叶片，现已对海南省的槟榔产业构成了巨大威胁^[2];红脉穗螟幼虫钻食槟榔的花穗、果实及心叶，造成5%的植株死亡^[3]。槟榔树体高大，株间距离紧密，药剂防治不方便，且存在农药残留与污染的风险。随着国民经济的发展，农业追求绿色、健康的发展目标。粘虫板、食物源诱剂、诱虫灯、性信息素^[4-6]等防治方法在绿色防控中被广泛应用。……
