Abstract:The Qufu surrounding areas Yang Shulin,wheat fields,orchards three habitats are the dominant species of spider-leopard (Pirta subpiraticus) at room temperature under conditions of the resistance,the results of preliminary analysis.The results showed that:Low doses of pesticides on the spider with the excitement of short-term role.Spraying of pesticides will farmland spiders too frequent emergence of drug-resistant,but also the emergence of drug-resistant agricultural pests,the damage increased,causing serious damage to biological control effect,the proposed farmers to use high efficiency and low toxicity pesticides,and concentration should also be sprayed Lower.In this paper,the results of farmland for the chemical control and better integration of biological control and provide a theoretical basis but also for the protection and use of spider reference.
