Prevalence of Apate monarchus (fab.) on Terminalia ivorensis (a. Chev.) from Olabisi Onabanjo University's Main Campus, Southwestern Nigeria

Insects and plants developed many different kinds of interactions during the course of their long-term cohabitation. This investigation aim was to determine the presence of Apate monarchus on Terminalia ivorensis from Olabisi Onabanjo University's main campus in Ago-iwoye, Ogun State. Samples were obtained from the underside of each tree, and statistics on the prevalence (%) of insect pests and the level of infestation were noted. The frequency and incidence of the pests were evaluated. Insects on Road 1 had a TPP rate of 73.91%, compared to a TIP rate of 52.17%, indicating that Road 1 had a higher TPP rate. The TPP rate is greater than the TIP rate for insects there, as seen by the TPP rate for insects on the right side of Road 1 (78.57%) and the TIP rate (42.85%). The insects on the left side of Road 1 have a TPP rating of (33.33%) and a TIP rating of (66.66%), which is lower than their TIP rating. Although the incidence rate was below 25%, the results showed that there were beetles on trees at a prevalence rate of above 70%. This may be a result of these trees' placement and spacing.
