Insects and other pests can be a serious constraint to food production, especially where resources for pest management are scarce. For example, in EDN 133, we responded to a question about problems with tomato leaf miner (Tuta absoluta) in Nigeria. Heavy infestations of this pest alone can reduce yields by 80 to 100% (Gebremariam 2015). The following resources continue an effort to strengthen our informational resources on pest monitoring and management.
