Abstract
African brinjal (Solanum aethiopicum), that is one of the
vegetable crops grown in Côte d’Ivoire, is severely affected by the shoot and
fruit borer Leucinodes orbonalis. This study was conducted to determine
the fluctuation of larvea population of L. orbonalis in brinjal cultivation.
An experimental field comprising four sub-plots was established. It contained
192 plants, with 48 plants per sub-plot. Sampling involved searching for and
counting larvae on 20 central plants in each sub-plot, within the shoots and fruits.
The average number of larvae increased gradually from 0.52 ± 0.11 larvae per
plant to 12.6 ± 1.86 larvae per plant, then decreased gradually to reach 2.13 ±
0.8 larvae per plant by the end of the fruits harvest. Average number of larvae
was significantly positively correlated with the average temperature and
negatively correlated with relative humidity.
