This bibliography will be of interest to all those involved in oil palm and coconut cultivation worldwide. It lists all the insect and mite pests of these palms, along with their natural enemies (parasitoids, predators, diseases). It includes all real pests, in other words of which there have been outbreaks, or potential pests. Only the most important reference or references are given for each species, and can be referred to for further information. This first part covers lepidopterans, the order that includes the largest number of species with 206 references, and hemipterans with 86 references; other orders will be covered in another bibliography.
