【摘要】 球孢白僵菌是节瓜颤马的一种虫生真菌。本文通过室内和田间试验研究了球孢白僵菌对节瓜蓟马的防治效果。室内试验表明,在1.5×108孢子浓度下成虫、蛹和若虫寄生率分别为70.00%、50.02%和17.78%。在2×108孢子浓度下田间土壤和植株喷施白僵菌,5d后可使蓟马成虫减少49.22%。球孢白僵菌对控制节瓜蓟马种群起了一定作用。更多还原

【Abstract】 B . bassiana was a kind of entomopathogenic fungi. Experiments were carried out in the lab and in the field on the effectiveness of using Beauveria bassiana to control Thrips palmi Karny.70.00% adults, 50.20% pupas and 17.78% nymphae of T.palmi were infected by the fungus by spraying one ml of conidial suspensions (1.5× 108) indoor experiment. A reduction of 49.22% in adult emergence was observed after 5 days when field soil and plants were sprayed with B. Bassiana by spraying one ml of conidial suspensions (2 × 10 ) . B. bassiana have some effect of controlling the population of T. palmi Karny.更多还原
