Cockroaches are the larvae of Scarabaeoidea from the order Coleoptera and Scarabaeoidea. Since 1995, they have found to infestation of Zoysia japonica (Taiwan grass) and carpet grass (Lyphoma macrophylla), which are more serious in some localities. The damaged plots have been damaged year after year. Year by year. At present, cockroaches have risen as a major pest of grassland. First, living habits and the law of occurrence Earthworms mainly focus on grass roots within 10 centimeters of the ground surface. In severe cases, the grass roots are eaten and grass dead. 1. Earthworms like to disturb the soil where there is loose soil and high sediment content. The sediment content of the Dayeyou grassland in the Haixia Park that occurred is more than 50%, and the sandy soil content of the seriously damaged Nanwan Avenue is as high as 60%. The more sand and loose soil is conducive to the activities of loquat. 2, high organic matter content. The soil used in Nanwan Avenue is sandy soil, rich in organic matter, and this grassland has been growing for eight years. The old grassroots remains underground after death, increasing the organic matter in the soil and providing a rich foodstuff for earthworms. 3, soil water content is less. According to reports from garden workers, the lack of watering has exacerbated the devastation caused by earthworms. 4. The grassland has been growing for many years, and there are many grassy roots that grow thicker. According to preliminary investigations, several grassy grasses that have been affected by earthworms have reached the age of more than four years. Second, control methods (a) Agricultural control 1. Afforestation Projects Pay attention to the problem of sediment concentration when filling the soil and grass to create an environment that is not conducive to the growth of alfalfa. Lands that have been badly damaged in successive years are also promoted to change soil. Uncovering the turf and shoveling 15-20 cm thick soil and replacing it with 15-20 cm thick clay will create an unfavorable environment for growth. It is the most important prevention and control in the future. ring. 2. Use some appropriate roadsides and wasteland to grow ramie and poison its adult. 3, using adult false animation, using manual shaking of the tree to kill the adults fell to kill. (b) Physical control Using adult phototaxis, black light or black-green single-tube dual-lamps (halving half of black light and half green light) are used to seduce adult worms during their lifetime. (III) Chemical Control Chemical prevention and control is currently the main method of preventing warts. 1, with 3% carbofuran 7-10 pounds per acre mixed sand 30-50 pounds of water after application, allowing the liquid to infiltrate the soil in contact with the body to increase efficacy. 2, with 3% methyl iso-phosphorus granules 10-14 pounds of mixed sand 30-50 pounds of water after application. 3, with 6% 666 per acre 2-3 pounds mixed sand 30-50 pounds of water after application. 4, with 50% phoxim EC 0.4-0.5 kg per mu fine sand 30-50 kg (first diluted with 10 times the liquid spray on the fine sand after the spray) spread after the application of water. (4) Biological control Biological control is one of the methods for comprehensive prevention and control of cockroaches. It should be actively tested and used for prevention and treatment. 1. The use of Beauveria tenella (Beauveria tenella) and Lactobacillus (DOOM and Japedemic in the United States) to control warts. 2. The use of insecticidal nematodes (Eetomopathogenic nematodes) to control cockroaches. 3. Use bumblebees to control cockroaches. 4. Use Prosenasiberita Fabricius to control cockroaches.
