| 摘 要： | 双生座壳孢(Aschersonia duplex Berk.)是刺绵蚧强有力的昆虫病原真菌。致死后的虫尸,长期留存枝叶上,是病原在野外的保存形式,并成为再次侵染源。病原借水传、虫传而散播。人工放菌最佳时期是2月中至3月中。田间试验表明,人工诱发致病后通过持续感染,使虫口密度不断下降,防治效果显著。

| Abstract: | The Aschersonia duplex Berk.is a strong pathogenic fungus on the scale Metaceronema japonica Mask. It could kill the scales while the dead bodies of infected insects remained infective on the plant branchs and leaves for long time in the field.The fungus was spread through insects and rain water. The optimal time for artificial dispersion of pathogen was from February 10th to March 10th. The field plot test demostrated that the reinfection caused by artificial dispersion could continuously reduce the population of insects. |
