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...

เพลี้ยกระโดด Tagosodes pusanus (distant): แมลงศัตรูข้าวชนิดใหม่ในภาคเหนือตอนบนของประเทศไทย Thai Agricultural
Jintana Chaiwong; Wantana Sriratanasak; Sukanya Arunmit; Urassaya Boonpramook.
Tagosodes pusanus (Distant) is one of the planthopper species, which has been reported as a minor insect pest in Thailand in 2000. The morphology of T. pusanus closely resembles the whitebacked planthopper, Sogatella furcifera (Horvath). However, it could be distinguished by the pattern of the dark markers of its forewings, pale yellow pronotum in the middle of the segment, color of the clypeus, and shapes and number of spines of aedeagus. The population dynamic of T. pusanus was studied by sampling in the rice fields using D-vac and Blower-vac sucking machines. The results showed that the number of T. pusanus was higher than S. furcifera at heading stages of the rice plants in Nakhon Nayok province in 2011. The relationship between the numbers of two...

พฤติกรรมการใช้สารฆ่าแมลงของเกษตรกรพื้นที่ระบาดของเพลี้ยกระโดดสีน้ำตาลในภาคกลาง Thai Agricultural

Main Factors affecting brown planthopper (BPH) outbreaks in the Central region from past up to now are cultivations of susceptible rice varieties and misused insecticide application. The aim of this research was to prove the misused of insecticide application in the hot spot area causing BPH severe outbreak. One hundred to one hundred fifty farmers from six provinces: Nakhon Nayok, Suphan Buri, Ang Thong, Chai Nat, Phitsanulok and Nonthaburi were interviewed during August to November 2010. The result found 56.5 to 100 percent of farmer sprayed insecticide for two to six times/seasons. Most farmers applied insecticide, especially Abamectin as cocktails mixed with two to six types of fungicides and/or herbicides. Most farmers were sprayed insecticide when...
