Role of different weather factors on fluctuation of fruit and shoot infestation of Spotted Bollworms, Earias spp. on Okra (Abelmoschus esculentus L.)

Muhammad A. Aziz, Mansoor ul Hasan, Jamshaid Iqbal, Amjad Ali.

Role of weather factors on the fluctuations of fruit and shoot infestation by Earias spp. on nine different okra genotypes was studied under field conditions at Post Graduate Agriculture Research Station, University of Agriculture Faisalabad, during 2006 and 2007. Maximum temperature, minimum temperature and average temperatures showed a positive effect; whereas, the relative humidity and rainfall exerted a negative effect on the fruit infestation, during 2006 and 2007, separately as well as on cumulative basis. The effect of maximum temperature, average temperature and relative humidity was significant and positive, during 2006 on the fluctuations of shoot infestation; whereas that of rainfall was negative and significant. During 2007, the maximum, minimum and average temperatures exerted a positive and significant effect on the shoot infestation while the relative humidity had a negative and significant correlation with the shoot infestation caused by Earias spp. on ‘okra’. On basis of an average for both years of studies, the maximum and average temperatures had a significant and positive effect, while the relative humidity and rainfall had a negative significant correlation, with the shoot infestation caused by Earias spp. on ‘okra’. Multiple Linear Regression Models revealed that the maximum temperature was the most important factor, which contributed maximum for fruit and shoot infestation, i.e., 60.50 and 53.20% for an average of both the study years, respectively. The impact of all the factors on an average of both the study years when computed together was found to be 67.00 and 55.50%, for fruit and shoot infestation, respectively.

Key words: Okra, Spotted bollworms, Temperature, Relative humidity, Rainfall, Shoot and fruit infestation.
