摘要:
通过室内不同温湿度及酸碱度条件培养，观察温湿度和酸碱溶液对南方根结线虫(Meloidogyne incognita)卵孵化和2龄幼虫（J2）存活的影响，为南方根结线虫种群动态的准确预测和科学防治提供理论依据。结果表明：南方根结线虫卵孵化的适宜温度范围是15~30℃，J2适宜存活的温度是10~25℃；土壤含水量在10%~30%内,南方线虫均可生长发育，但含水量为30%时，对卵孵化和J2存活均具有明显的抑制作用；pH 5~8时,南方根结线虫卵孵化率与J2存活率均较高,表明该虫在弱酸弱碱和中性环境中更易生存。由此可见,不同的温湿度和酸碱溶液对南方根结线虫卵孵化和J2存活均有显著影响。
Abstract:
The influence of temperature，humidity and acid-base solution on hatching and survival of second-stage juveniles (J2) of M.incognita was examined through indoor breeding under corresponding condition.The results showed that the optimum temperature was 15~30℃ for hatching of M.incognita while 10~25℃ for survival of J2.The adaptive moisture range was wide.It was tolerable for M.incognita to grow and develop when the soil moisture content was 10%~30%.However，the soil moisture content over 30% had the negative effect on hatching and survival of J2 of M.incognita significantly.Under the condition of weakly acidic，alkaline and neutral environment (pH 5~8)，M.incognita had the higher rate of hatchability and livability for J2.In conclusion，temperature，moisture and acid-base solution were important factors which could observably influence hatching and survival of J2 of M.incognita.
