摘  要：
在田间自然发生条件下,研究了5个不同腰果品系对腰果细蛾的抗虫性。结果表明,5个不同腰果品系的抗虫能力为HL2-21>GA63>DF2>HL2-13>FL30。HL2-21对腰果细蛾的抗虫能力最强,其蛾害指数为12.30%(抗),显著低于其他腰果品系。GA63也有较强的抗虫能力,其蛾害指数为21.80%(中抗),显著低于DF2、HL2-13和FL30。DF2和HL2-13的抗虫能力较弱,其蛾害指数分别为28.40%(中抗)和31.30%(感虫);FL30的抗虫能力最弱,其蛾害指数为40.80%(高感),显著高于其他腰果品系。

摘  要：
The resistance of five cashew germplasms to cashew miner was evaluated under field conditions in this study. The results showed that the resistance of the five cashew germplasms could be ranked from strong to weak as followed:HL2-21,GA63,DF2,HL2-13 and FL30. The HL2-21 was the most resistant germplasm to cashew miner,with a damage index of 12.30%,which was significantly lower than that of other germplasms,ranked as resistant,followed by GA63,with a damage index of 21.80%,significantly lower than those of DF2,HL2-13 and FL30,ranked as moderately resistant. The resistance of DF2 and HL2-13 was weak,with the damage indexes as 28.40% and 31.30%,respectively,ranked as susceptible. FL30 was the most susceptible germplasm,with a damage index of 40.80%,significantly higher than that of other germplasms,ranked as highly susceptible.
