The impact of climate variability on insect pest occurrence was studied to establish information beneficial to agricultural pest management by monitoring the rates of pest invasion using light trap equipment and ascertain benchmarks of climate changes that influence distribution of the species of brown plant hopper, green leaf hopper, stem borer and parasitic wasp.

Correlation and graphical analysis were employed to determine the significant relationship between the two years monthly totals of the pests and three climatic variables: temperature, rainfall and relative humidity. Lag variables up to five months were also included.

The result showed high significant correlation with brown plant hopper and temperature lag 4 months (r2 = 0.630915), the green leaf hopper and temperature lag 4 months (r2 = 0.7620), the stem borer and temperature lag 5 months (r2 = 0.62171). Unusual result however was obtained where the total of parasitic wasp for the current month is highly significant with rainfall and relative humidity for next month.

Based on the observed facts, the following conclusion was drawn: (1) Climate variability affect insect pest behavior and dynamics although the impact vary with species; (2) The behavior of wasp confirms folklore meteorology; and (3) The impact of climate variability on insect pests occurrences are good inputs to farm weather forecasting.

Further monitoring of the insect dynamics and climate variability is recommended for future comprehensive study in relation to climate change.
