A study on ecological engineering on rice to develop sustainable means to reducing crop losses due to rice pest outbreaks were taken in wet season, 2011 at Chiangrai Rice Research Center and in farmer’s field at Phan District, Chiangrai Province. The main objective was to compare between of Ecological Engineering (EE) means (EE site) and farmer’s practices (control site) as well as the effects on numbers of pest and natural enemies. The numbers of species and amount of each insect pest and natural enemies were collected by visual counting, sweep net, yellow pan trap, egg bait trap and D-vac machine. It was found that : the major pest in EE site was Nephotettix spp. Whereas major natural enemies was spider such as Lycosa psedoannulata, Oxyopes sp., Argiope...

Main objective of this study was to evaluate the relationship between climate changes and rice disease s epidemics in Chiangrai and Phayao provinces. The study was conducted at Chiangrai Rice Research Center during the year 2011-2013 by monthly broadcasting two popular rice varieties in the area; Phitsanulok 2 and Sanpatong 1. The experiment was carried out in Split plot in RCB Design with 3 replicates having month as main plot and variety as sub-plot. Disease incidence and severity were evaluated at 3 growth stages i.e. 20, 50 and 90 days after sowing. Concurrently, Disease incidence and severity were recorded for rice diseases in the farmers’ fields of Chiangrai and Phayao provinces having infected at 10 rai and above. Disease data showed that both rice...
