| Abstract: | Alcidodes juglans Chao has one generation per year in Guizhou province and overwinters in adult stage in bark crevices,hassock and upper soil layer.In April,the adult begin to feed on the plants for supplement nutrient,then copulate and oviposit.The peak of oviposition is in the early May,and the adult begins to emerge in the end of June.In the early of November it begins to overwinter in the adult stage.When applied omethoate and DAGONGCHEN two times in the end of April,the fruit-preserving effect was up to 72.7%,and when applied white muscardine in November the effect was up to 62.0%.The application of white muscardine has a sustainable effect for the control of this pest. |
