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...

This study, we isolated and evaluated the antagonistic bacteria from healthy corn plant, 10 bacterial antagonists from 310 strains were mixed synthetic medium for preliminary test with corn borer. The Cut young corn pod that dipped with antagonistic bacteria suspension in CRD design were investigated under plastic box conditions, compared to plants treated with synthetic insecticide (cypermetrin). Fifty corn borer per plant arranged in CRD design were investigated under control conditions. The treatment with strain BCA2 BCA4 BCA7 BCA8 and BCA10 provided the highest mortality of corn borer with 100 percent reduction after 6 hr and BCA4 BCA8 and BCA10 showed the highest mortality of corn aphid with 100 percent reduction at 48hr after treated. Moreover, the...

Insect survey using light traps and the field survey for collecting insect pests and natural enemies were conducted at Surin Rice Research Center during February 2014 to January 2015. The main objective of this study was to investigate the correlations between environmental factors and numbers of insect pests and natural enemies. The results revealed that rainfall, temperature and relative humidity were slightly correlated with numbers of insect pests and natural enemies. Additionally, number of pests was negatively correlated with number of natural enemies. Negative correlations were observed between number of parasitic wasps and numbers of white backed planthoppers, brown planthoppers, green leafhoppers and zigzag leafhopper. Number of orange ladybugs...
