Última การติดตามความต้านทานต่อสารเคมีป้องกันกำจัดแมลงของเพลี้ยกระโดดสีน้ำตาลในภาคตะวันออกเฉียงเหนือของไทย Thai Agricultural Sukanya Arunmit; Wantana Sriratanasak; Jintana Chaiwong; Urassaya Boonpramook. Brown planthopper (BPH), Nilaparvata lugens (Stål), is a major insect pest of rice in Thailand.Because of their ability to adapt to host plant and environment, the BPH becomes an extremely destructive pest and difficult to control. The purpose of this research is to monitor the insecticide resistance of BPH in North Eastern (NE) Thailand. The BPH populations were collected from the outbreak areas in 9provinces during 2011 to 2012. The toxicity (LD50) of 10 insecticides was conducted using Topical bioassay method. The results showed that the BPH populations from 7 provinces were resistant to ethiprole and isoprocarb. The NongBua Lam Phu population was the widest spectrum of resistance to the tested insecticides,whereas, the BPH population from Sisaket was...

Brown planthopper (BPH) is a major insect pest of irrigated rice cultivation areas in lower north, central and northeast Thailand. The field experiments were conducted to evaluate the efficacy of nine insecticides to control BPH in farmers’ fields at Suphan Buri, Nakhonayok and Ubon Ratchathani provinces. The results showed that the sulfoxaflor 50 % WG and pymetrozine 50 % WG were the most effective insecticides. The ratios of BPH/mirid bug (MB) in the buprofezin and pymetrozine fields were lower than other fields, which may indicate the less toxicity to MB compared with other insecticides. Moreover, toxicity of each insecticide to MB was investigated using a leaf dipping method and the result indicated that pymetrozine 50 % WG was the lowest toxicity to...
