Pest Management Science 72: 1071–1089
Keywords:
Notes: We present geographic distribution and field-level incidence of the most prominent pest and disease invaders, introduce readily-available management options and research needs. Monitoring work reveals that several exotic mealybug and (red) mite species have effectively colonized SE Asia’s main cassava-growing areas,occurring in respectively70%and54%of fields, at average field-level incidence of 27±2% and 16±2%. Although all main pests and diseases are non-natives, we hypothesise that accelerating intensification of cropping systems, increased climate change and variability, and deficient crop husbandry are aggravating both organism activity and crop susceptibility.
