Seasonal incidence of coleopteran pests in relation to weather in mango (Mangifera indica).
The seasonal occurrence of Coleopteran pests infesting 15- to 20-year-old mango cv. Neelum trees was studied in a field experiment conducted in Andhra Pradesh, India. Flush, fruit and stem damaging species viz., Rhynchaenus mangiferae, Apoderus transquebaricus, Deporus marginatus, Myllocerus discolor, Sternochaetus mangiferae and Batocera rufomaculata were recorded in the experimental fields. The stone weevil Sternochaetus mangiferae caused the highest yield and quality losses in mango. The incidence of R. mangifera, A. transquebaricus, D. marginatus and M. discolor was negatively correlated with minimum and maximum temperature, but positively correlated with rainfall and relative humidity. The occurrence of S. mangiferae and B. rufomaculata were positively correlated with maximum and minimum temperature and negatively correlated with relative humidity and rainfall.
