| Abstract | ||
| Effect of temperature and relative humidity on the population fluctuation of combined larvae; pupae development stages and infested leaves percentage of the broad bean leaf miner ( Liriomyza frifolii ) ( Burgess) on fali season at EI Behaira- Governorate throughout two successive years (2001/2002 and 20021 2003) were investigated .From these result's concluded that these relations in most cases were insignificant negatively. But night temperature show significant positive indicating simple correlation values during the two seasons . The partial regression values demonstrated the same trend were insignificant and negative at 0.05 % probability level .The highest influence on population of insect stages was that of night temperature whereas daytime temperature and relative humidity % were non evident effect on population count during fali seasons .The explained variance percentage (EV. ) it being 56.4%:25.6 % and 51.6%:23.8 % for both years (2002 &2003 ) respectively . | ||
