The Relationship between population fluctuations of Helopeltis theivora Waterhouse, availability of Cocoa Pods and Rainfall Pattern

Investigation on factors affecting the population fluctuations of Helopeltis theivora in relation to food supply and rainfall in the field was conducted. Results showed that population fluctuations seem to be dictated by rainfall and numbers of available pods as shown by positive correlations betw...
