“…However, wind speed and sunshine hour showed negative non-significant correlation (r=-0.528 and -0.390) with jassids incidence during 2018 and positive nonsignificant and positive significant correlation (r= 0.234 and r= 0.717*) respectively during 2019. Present finding was coordination with Mahmood et al (2002) [11] , Selvaraj et al (2010) [16] reported that incidence of leafhopper, A. biguttula biguttula showed positive and significant correlation with maximum and minimum temperatures. Relative humidity and rainfall were negatively and non-significantly correlated with population fluctuation.…”

Major insect pest of okra viz., jassid (Amrasca bigutulla biguttula), whitefly (Bemisia tabaci), and shoot and fruit borer (Earias vittella) damaged heavily during the kharif. The incidence of leafhopper, whitefly, shoot and fruit borer and natural enemies show correlation with weather parameters, minimum temperature showed significantly positive correlation (r = 0.611* and 0.807**) with jassid incidence during both the year of study. Maximum temperature showed non-significant negative correlation with jassid incidence during 2018 and significantly positive correlation during 2019 and correlation values in respective years were (r= -0.234 and 0.836**). Relative humidity and rainfall showed negative nonsignificant correlation with Whitefly incidence during both the years and correlation values in respective years were (r= -0.323, -0.092 and r= -0.562, -0.580). Minimum temperature showed positive significant correlation (r= 0.757** and 0.835**) during both the years. Maximum temperature showed nonsignificant negative correlation with per cent shoot damage during 2018 and significantly positive correlation during 2019 and correlation values in respective years were (r= -0.138 and 0.810**). Whereas, wind speed and sunshine showed positive non-significant correlation (r= 0.040 and 0.171) during first year and negative non-significant correlation (r= -0.373 and -0.064) during second year. minimum temperature and Clubiona sp. showed positive significant correlation (r= 0.438 and 0.493) during both the years.

“…However negative and non-significant effect of rainfall was observed on Jassid population. The present findings can be compared with those of (Tariq Mahmood et al, 2002) who find non-significant correlation of rainfall towards increasing or decreasing of Jassid population. The present results can also be compared with Iqbal (Iqbal et al, 2008) who reported that rainfall showed maximum contribution in population fluctuation of Jassid on okra.…”

“…However, maximum use of synthetic insecticides creates numerous problems to living organisms (Malik, Javed, & Ayyaz, 2015). The insecticides application doesn't provides an immediate solution to control the pests (Tariq Mahmood, Hussain, Khokhar, Jeelani, & Ahmad, 2002). It has been reported that about two million peoples affected with exposure to insecticide and about 40000 died due to insecticide poisoning (Rajput, 2004).…”

The present study was carried out to screen the okra genotypes against Jessid and to determine the role of abiotic factors on the population dynamics of this pest on okra under the agro climatic conditions of D.I. Khan, Pakistan. The results of the study revealed that the peak population of Jassidi. e.,3.31/leaf was observed on July 2, and minimum population was recorded on August 6, with 1.57 Jassid/leaf. The HPSI (Host plant susceptibility indices) showed that genotype Anmol and Climson was found to be susceptible with 14% HPSI, while minimum HPSI i.e., 11% was recorded on okra cultivar Sabzpari, Butter-5 and BP-1. Simple correlation analysis revealed that rainfall had maximum contribution of 24.99% in the population fluctuation of Jassid followed by maximum and minimum temperature which had a non-significant and positive correlation with Jasssid population .The role of maximum temperature was 13.01% while minimum temperature has 6.83% role in the population fluctuation of Jassid.

“…Arif et al (2006) reported that the temperature and rainfall had positive relationship while the relative humidity had negative relationship. Mahmood et al (2002), who reported about the correlation effect. It is observed that highest and the least temperature was positively correlated although relative humidity and rainfall was negatively linked.…”

A bout 18 %, agriculture contributes in Gross Domestic Product (GDP). Cotton has 0.8 % share in the economy and 4.5% in the agriculture values of Pakistan. Cotton is an important crop that's why it is believed as the lifeline of the Pakistan (Anonymous, 2018). Cotton is the world's most important fibrous crop and it grows in both tropical and sub-tropical areas of universe (Bala et al., 2019). Throughout the year of 2018 and 2019, the cotton production keeps on at 9.861 million bales. Sometime the production of the crop was also affected by meteorological factors. The production of the cotton crop in 2019 remained at the 2373 Ha while the yield was 606 Kgs/Ha. Textile is the major sector of the Pakistan. The exports of the cotton and cotton textile during 2019 from July-March remained at 9771 US Million dollars (Anonymous, 2018). Pakistan is at 4 th after US, China and India in case of cotton production (Anonymous, 2018). In between sucking pests of cotton; whitefly, jassid, thrip, recorded as greatest damaging pests (Arif et al., 2006;Ali and Aheer, 2007;Salman et al., 2011). Lint quality and Abstract | The experiment was conducted at Faisalabad in the trail region of UAF during 2018 to understand response of sucking insect pest fauna against the transgenic and non-transgenic cotton varieties. To figure out the response of these pest with the meteorological factors against whitefly, thrips and jassid. For this experiment RCBD Design was used. The five varieties of cotton were used in which IUB-2015, MNH-886, FH-142 and CEMB-33 were the Bt varieties while FH 942 was the non-Bt. The highest population of whitefly (4.707/leaf ), thrips (4.073/leaf ) and jassid (3.940/leaf ) was found in July on MNH-886, CEMB-33 and FH-942 respectively. Extreme in addition least temperature had positive outcome on pests including whitefly, thrips and jassid culture. In case of thrips, whitefly and jassid rainfall, relative humidity and sunlight exposure had negative effects.The moisture having negative response with the whitefly and intermediate with the thrips population while with the jassid it exhibited positive correlation. Sucking pests also had an influence on the yield factor.
