Abstract
The study aimed to survey the arthropod fauna associated with Tomato plantation by using different sampling techniques. The study also extended to investigate the population density and and fluctutions seasonal abundance of the common sucking pests(Whitefly, Bemisia tabaci (Genn) and Aphids, Aphis gossypii(Glover)) and the bitting leafminer Liriomyza congesta(Beck), as well as The effect of mean temperature and relative humidity on these pests. The effect of certain pesticides on these insects was also taken in to consideration a) Survey studies of insects in tomato plants in fields revealed the presence of twenty six (26) insects belonging to twenty two (22) families and eleven (11) orders recorded using three methods (Direct count on plants, light traps technique and sticky traps. Among these species, the number of harmful pests represented the majority (three insect species). Only one species was recorded as a pollinator.
(b) The most dominant and abundant sucking pests were whitefly, Bemisia tabaci , the melon aphid, Aphis gossypii(Glover.) as well as serpentine leafminer, Liriomyza congesta (Beck.). The results showed that the light trape to be the best method to collect all the insect species, the yellow sticky board traps had a remarkable selectivity for attracting certain insects, while direct count method seemed to be suitable for large insects only.
Generally, the obtained findings demonstrated that different methods, i.e. light trape, yellow sticky board traps and direct count technique were suitable for surveying the population density of the insects.
