摘　　要：为明确吉安市主要油茶产区两种不同生境下虫害的发生情况,于2022年10月~2024年10月对吉安市所属5个县(区)两种生境(低产/高产油茶林)开展了虫害调查。通过初步调查,共调查到油茶虫害5目20科26种,低产和高产油茶林生境分别是5目20科26种和5目18科23种,均以鳞翅目虫害为主,科数占比分别是45.00%和44.44%,种数占比分别是42.31%和41.67%。五个县(区)低产油茶林虫害科数和种数均比高产油茶林多,科数最多的为永丰县和安福县,低产生境15科,占比75.00%,高产生境12科,占比66.67%;井冈山市最少,低产生境10科,占比50.00%,高产生境9科,占比50.00%;虫害种数最多的是永丰县,低产生境19种,占比73.08%,高产生境14种,占比58.33%;虫害种数最少的是井冈山市和青原区,低产生境13种,占比50.00%,高产生境11种,占比45.83%。结果表明,在吉安主要油茶产区,两种不同生境下油茶虫害的发生种类和群落组成存在差异,且低产油茶林生境下虫害种类、数量和危害程度均高于高产油茶林。In order to clarify the species and community characteristics of oil tea pests in two different habitats in the main Camellia producing areas in Ji’an,a pest survey was carried out in two habitats(low/high-yield oil tea forest)in five counties of Ji’an city from October 2022 to October 2024.Through preliminary investigation,26 main pests in C.oleifera were investigated,belonging to 20 families,5 orders,in which 26 species from 20 families and 5 orders in low-yield habitat and 23 species from 18 families and 5 orders in high-yield habitat.The main pests were Lepidoptera of low and high-yield habitats,and the number of families was 45.00% and 44.44% respectively,the number of species was 42.31% and 41.67% respectively.Five counties had more families and species in low-yield habitat than in high-yield habitat.The highest number of families are Yongfeng and Anfu county,with 15 families in low-yield habitats accounting for 75.00% and 12 families in high-yield habitats accounting for 66.67%.The lowest number of families is Jinggangshan city,with 10 and 9 families in low and high-yield habitats,accounting for 50.00%.The highest number of species is Yongfeng county,with 19 and 14 species in low-yield and high-yield habitats accounting for 75.00% and 66.67%,respectively.The lowest number of species are Jinggangshan city and Qingyuan county,with 13 and 11 species in low and high-yield habitats accounting for 50.00% and 45.83%,respectively.The survey results indicate that the types and community composition of oil tea pests in two different habitats in Ji’an were different,and the species,quantity and harm degree of the low-yielding were higher than those of the high-yielding oil tea forest.
