The present study was conducted under the ecological conditions of district Rahim Yar Khan (Punjab), Pakistan. After completing the whole research trials, maximum population was recorded from bean fields 54.56% (N=329) and least population was recorded from okra fields i.e. 45.44% (N=274). Where in case of bean fields, maximum population was recorded during 6th sampling (52±13.51), followed by 37±2.90 (7th and 9th sampling), 36±2.19 (3rd sampling) and least values were recorded during 4th sampling (18±10.54); whereas, species abundance was recorded utmost during 6th sampling (31 species) at temperature and humidity of 32.4 ºC, 30.5 ºC and 32%, 55%, respectively; however, least species abundance was recorded during 4th sampling i.e. 14 species at 26 ºC (temperature) and 33% (humidity). In case of okra fields, maximum population was recorded during 6th sampling (39±8.20), followed by 29±1.13 (9th sampling), 28±0.42 (10th sampling) and least value was recorded during 4th sampling (24±2.40); whereas species abundance was recorded utmost in 6th sampling (24 species) at temperature and humidity 26 ºC and 36%, respectively; however, least species abundance was recorded during 3rd sampling i.e. 13 species at 24ºC temperature and 30% humidity. Form okra fields, maximum relative abundance 4.38% (N=12) was recorded for Alysinae spp. andin bean fields maximum relative abundance 3.34% (N=11) was recorded for Dinocampus coccinellae. Form Okra fields higher ratio was recoded for genus Musca (Family Muscidae) 5.47% (N= 15). From bean fields, Apis was recorded as an extraordinary contributing genus with relative abundance of (4.8%; N=16). Diversity (H') was recorded maximum among bean fields (0.0823) and least was recorded among okra fields (0.0685). Evenness ratio was also recorded in same context (0.0327 and 0.0281, respectively). Dominance was recorded maximum from bean fields (1.0281) and least from okra fields (1.0327). However, richness was a little bit recorded high among okra fields (15.9602) and least among bean fields (15.1457). Analysis of Variance (ANOVA) among both vegetable fields (okra and bean) showed non-significant results (F=0.07; P=0.7942).
