Effect of non-catalytic infrared ray on the grain moth Sitotroga cerealella (lepidoptera: gelechiidae)
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
This study was conducted under laboratory conditions to find out the effect of the non-catalytic infrared on the mortality rates and development of various stages of the grain moth Sitotroga cerealella. Result of the study revealed that treated eggs, first and fourth instars, pupae and adults mortality increased by increasing non-catalytic infrared waves exposure time from 40 and 60 seconds at 40 and 50? C. Highest egg mortality (56.7%) and hatching period (6.1 days) was reported on the exposure of 60 seconds at 50? C while the lowest values 3.3% and 4.5 days respectively was reported for the control treatments. Similar conditions were reported for the first and fourth instars, pupae and adults mortality. Infrared waves exposure for 60 seconds at 50? C significantly influenced the development of S. cerealella and showed 53.31% first stage larval mortality, 50% fourth stage larval mortality, 46.7% pupal mortality and 66.7% adult mortality. Furthermore, it was reported that infrared wave did not have any negative effect on the seed germination and 60 second exposure at 50 ? C showed 96 percent seeds germination.
