การใช้กับดักแสงไฟคาดการณ์การระบาดของเพลี้ยกระโดดสีน้ำตาลในจังหวัดปราจีนบุรี Thai Agricultural
Wannaphan Janlapha; Chalermpol Chalermpolyotin.
Major pest in irrigated rice growing area of central and lower northern region since 1975 is brown planthopper. The factors of BPH outbreak are varieties seed rate fertilizer use misuse of chemical. The monitoring of population density is very important for forecasting the BPH outbreak. Light trap, an effective tool for monitoring the outbreak of BPH was conducted in hot spot areas. Light trap was set in Prachin Buri Rice Research Center while surveying in farmers’ field in hot spot areas of outbreak in Prachin Buri province were investigated during January 2011 to December 2012. The number of BPH from light trap was counted everyday throughout the year. The results showed that light trap could collect large number of BPH. The peak of BPH in light trap...

Example populations of brown planthopper outbreak in Phitsanulok province, Bring test the reaction virulence of the rice varieties with different resistance genes. Individual insect separate test showed that BPH samples collected during the years 2010 by the diversity of biological species in a mixed group of BPH into three groups : Group 1 biotype 4 BPH resistance genes were Bph 3, bph 4 and bph 2 + Bph 3 group 2 biotype 5 BPH resistance genes were bph 2 + Bph 3 and group 3 New biotype is resistant gene Bph 3 and bph 2 + Bph 3 as the province of Phitsanulok and Kamphaeng Phet group 1 biotype 4 were 37.50 and 14% in group 2 biotype 5 were 10.42 and 20% and group 3 new biotype were 52.08 and 66%, respectively, that none of the insect population biotype 3....

ความหลากหลายของแหล่งที่มาของเพลี้ยกระโดดสีน้ำตาลต่อความรุนแรงในการทำลายข้าวพันธุ์ต่างๆ Thai Agricultural
Orrachoan Poolsiri; Noppadol Kiripetch.
The brown planthopper (BPH) is one of the most important insect pests imposing limitations on the production of rice. The objective of this study is to investigate the effects of 32 BPH populations on 21 varieties of rice with differences in resistance to BPH while the TN1 variety used for a susceptible check. The previou by seedling box screening techniques and Standard Evaluation System for Rice. However, the limitation of this study was the analysis of data using only cluster analysis to group the sources of BPH and rice varieties but there was no detailed analysis for each group.

The brown planthopper (BPH), Nilaparvata lugens (Stål) has been a major pest in irrigated rice growing areas of central and lower northern region since 1975. The monitoring of population density is very important for forecasting the BPH outbreak. Light trap, an effective tool for monitoring the outbreaks of BPH was conducted in hot spot areas. A light trap was set in Khlong Luang Rice Research Center while surveying in farmers’ fields in hot spot areas of BPH outbreak in Bangkok and Nonthaburi province were investigated during January 2011 to November 2012. The number of BPH caught from light trap was counted everyday throughout the year. The results showed that light trap could collect big number of BPH. The peak of BPH in light trap was in March of each...

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...

The brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most serious insect pest of irrigated rice in the central and lower areas of Northern Thailand. In upper North of Thailand, the first and serious outbreak was found during year 2011 and 2012. The misused insecticide over a period of time with extensive and intensive application is causing BPH outbreak. Therefore, the goal of this research was to monitor the insecticide resistance of BPH in the Northern, Thailand. BPH were collected from 12 outbreak fields of the Northern region namely: Chiang Rai, Chiang Mai, Mae Hong Son, Nan, Phrae, Tak, Phetchabun, Kamphaeng Phet, Phitsanulok, Phichit, Nakhon Sawan and Uthai Thani between the periods of 2010 to 2012. The toxicological tests (LD50) of...
