蜘蛛耦合抑菌复合剂有效控制水稻病虫害发生的研究
COUPLING OF PREDATOR SPIDERS AND BACTERIOSTATIC AGENT BENEFITS TO CONTROLLING RICE DISEASES AND PESTS
摘要
Abstract
To evaluate the efficacy of a biological control strategy integrating generalist predatory spiders with beneficial microbial consortia in managing rice pests and diseases,field trials were conducted in rice fields located in Jianhu County,Jiangsu Province,and Yichun City,Jiangxi Province.In the biological control fields,chemical pesticides were completely replaced by the release of predatory spiders to control insect pests and the application of beneficial microbial consortia to combat diseases.Conventional chemical pesticide applications were employed in the chemical control fields.The results demonstrated that,in Jianhu,spider density in the biological control fields was significantly higher than in the chemical control fields(wolf spiders exceeding 30 individuals/m2,cob-web spiders and sheet weaver spiders both exceeding 20 individuals/m2in the biological control fields,compared to fewer than 10 individuals/m2 in the chemical control fields;P<0.05).The density of rice planthoppers peaked at 250 individuals/m2in the biological control fields,significantly higher than that in the chemical control fields(P<0.05).However,the incidence rates of rice blast and sheath blight were significantly lower in the biological control fields(P<0.05).In Yichun,the difference in spider density was even more pronounced(wolf spiders exceeding 40 individuals/m2in the biological control fields versus fewer than 10 individuals/m2in the chemical control fields;P<0.05).Major insect pests,such as rice planthoppers and rice leafrollers,exhibited significantly higher densities in the biological control fields compared to the chemical control fields(P<0.05).However,no significant differences were observed for green leafhoppers or rice stem borers between the two treatments(P>0.05).Additionally,the incidence rates of rice blast and sheath blight did not differ significantly between the biological and chemical control fields(P>0.05).In summary,the integrated biological control strategy combining"microbial disease prevention"and"spider pest suppression"effectively mitigated outbreaks of major rice pests and diseases.Furthermore,the rice yield in the biological control fields reached over 98%of that in the chemical control fields,further confirming the feasibility and potential of this spider-microbe-based biocontrol technology for broader adoption and application.关键词
