Insect Pests of Tomato (Lycopersicon Esculentum) in a selected plot within the Michael Okpara University of Agriculture Umudike in Abia State:- Ehumadu, Okechukwu
ABSTRACT
The insect pests of the tomato
plant Lycopersicon escu/entum were surveyed between the months of May to August
2006 in a selected plot within the Michael Okpara University of Agriculture,
Umudike in Abia State. Two varieties of Lycopersicon esculentum; Roma VF and
Derica VF were used for the survey. The tomato seeds were sun-dried and then
planted in two seed trays in sterilized soil. The seeds were then transplanted
into the main field after one month in the nursery. Sampling or inspection for
the insect pests started afler one week of transplanting and were made between
the hours of 7-8 am and 6-- 7 pm on weekly basis. Twelve species of insects
belonging to five different orders were encountered. Of these, Bemisia tabaci
(Hemiptera: Aleyrodidae), the caterpillars of Spodoptera exigua (Lepidoptera:
Noctuidae), and Plusia spp. (Lepidoptera: Noctuidae) were found to cause very
serious damage to the plant. The occurrences of the various insects varied
during the survey period. Various parts of the tomato plant were attacked by
the insects with the vegetative and fruiting stages recording the highest
number. Bemisia tabaci had the highest average percentage abundance of 75.0%
followed closely by Spodoptera exigua and Plusia spp. which recorded 73.3% and
66.6% respectively.
