Occurrence and damage regularity of Conogethes punctiferalis in macadamia orchards and its damage preference to different macadamia varieties
摘要
Abstract
In order to understand the occurrence and damage regularity of Conogethes punctiferalis in macadamia orchards and its damage preference for different macadamia varieties,the dynamics of C.punctiferalis in five macadamia varieties including Guire No.1,JW,A16,Own Choice,and HAES695 in Nanning macadamia orchards,were monitored by traps of sugar-vinegar-wine solution and sex pheromone from 2022 to 2024,and the five-point sampling method was used to investigate the damage of the fruits of five macadamia varieties at different growth periods.Fresh peels from five varieties were used to feed newly hatched lar-vae of C.punctiferalis.The larval developmental duration,pupal stage,pupal weight,and adult lifespan were measured and an-alyzed to compare the effects of different varieties on the growth and development of C.punctiferalis.The results showed that C.punctiferalis adults began to emerge in macadamia orchards of Nanning from early and middle of May,and the adult peak periods were in late June,late July to early August,and late August to early September.The C.punctiferalis larvae began to damage macadamia in mid-May,and the peak periods of larvae damage were in early June,late June to early July,early-mid August and early-mid September.There was a significant preference of the C.punctiferalis for the damage of different macadamia varieties.Among macadamia varieties,A16 and Guire No.1 were more conducive to the growth and development of the larvae,and their fruit damage was more serious than that of the other three varieties,with the damaged fruit rate of 21.8%and 15.6%,respec-tively.The C.punctiferalis larvae raised with A16 and Guire No.1 macadamia grew and developed rapidly,with greater pupal weight and shorter pupal stage.The fruits of JW and Own Choice were moderately damaged by C.punctiferalis,and HAES695 were almost unaffected by C.punctiferalis.Therefore,the key control period of C.punctiferalis is early to mid-May,late June,late July to early August and late August to early September.For the orchards with multiple varieties,it is important to prevent the damage of C.punctiferalis to Guire No.1,A16 and JW.关键词
