The present research work was conducted to accord assortment and comparative abundance of foliage insects on lemon (Citrus limon L.) and fruiter (Citrus reticulata) during the flowering season of these orchards. Among both fields, total 4547 specimens were collected during entire sampling and maximum population was recorded from fruiter orchards 68.24% (N = 3103) and least population was recorded from lemon orchards i.e. 31.76%. Wherein in case of lemon orchard, maximum population was recorded during 6th sampling (350 ± 145.38) and least as well as equal values were recorded during 1st, 2nd and 7th sampling (69 ± 53.32). Whereas, species abundance was recorded utmost and equal during 4th and 9th sampling (32 species) at temperature and humidity of 29.2°C and 31.5% and 35°C and 58%, respectively. However, least species abundance was recorded during 1st sampling i.e. 17 species at 29ºC (temperature) and 37% (humidity). In case of fruiter orchards, maximum population was recorded during 5th sampling (537 ± 160.30); while, least value was recorded during 1st sampling (119 ± 135.27). Whereas, species abundance was recorded utmost in 5th and 4th sampling (30 and 27 species, respectively) at temperature and humidity of 33.4 ºC, 38% and 28.6 ºC, 30%, respectively. However, least species abundance was recorded during 1st sampling i.e. 26 species at 32.6ºC temperature and 32% humidity. Diversity (H') was recorded maximum from fruiter orchards (0.7758) and least was recorded from lemon orchards (0.3610). However, richness was a little bit recorded high from fruiter orchards (23.9561) and least for lemon orchards (23.7652). Results of Analysis of Variance (ANOVA) among both orchards showed non-significant results (F = 0.48; P = 0.4997).
