摘要
通过对'O.C''H2''A4''A16''816''344'和'333'等7个澳洲坚果品种花期、挂果初期、果实膨大期和养分积累期的蓟马种类和数量以及收获前果实的虫果率调查,探究不同澳洲坚果品种的蓟马种群数量和为害情况的差异.结果表明:为害澳洲坚果的蓟马有7种,花期蓟马以成虫虫态为主,果期以若虫虫态为主,色蓟马为优势种.'344'品种蓟马发生最轻,'H2'和'A16'品种发生较轻;'816'品种蓟马发生最重,'333'品种发生较重.
Abstract
Seven macadamia species,O.C,H2,A4,A16,816,344 and 333,were selected to investigate the population and damage of thrips.This study investigated the species and quantity of thrips at flowering stage,early fruiting stage,fruit ex-pansion stage and nutrient accumulation stage.At the same time,the damage rate of the fruit before harvest was investigat-ed.The results showed that at least 7 species of thrips could harm macadamia.The thrips are mainly adults at flowering stage and nymphs at fruit stage.Thrips coloratus is the dominant species.In the comprehensive evaluation of the occur-rence degree of thrips,344 was the lowest,followed by H2 and A16,816 was the highest,followed by 333.
