Insect Pests Of Tomato (Lycopersicon Esculentu In A Selected Plot Within The Michael Okpara University Of Agriculture, Umudike In Abia State
ABSTRACT
The insect pests of the tomato plant
Lycopersicon esculentum 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 escuientum; 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 after one week of transplanting and were made between the
hours of 7 — 8 am and 6 — 7 pin on weekly basis. Twelve species of insects
belonging to five different orders were encountered. Of these, Bernisia 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. Beinisia 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.
