Do the diversity of plants and sulphur application influence the population fluctuation of insect predator?

Abstract

Results reveal that the abundance of the target predators was affected indirectly in different cultivated plants after sulphur application, as a result of different plant nature and consequently the population of pests invaded. At all inspection periods, it was observed that the mean numbers and abundance of adult predators on marrow plants was more than that reported in an okra field. Under all inspection times, there was a significant difference between the mean numbers of recorded predators, where Coccinella adults recorded the highest mean numbers, followed by Chrysoperla adults. Stethorus adults recorded the least mean number, either before or after sulphur application.
