Research is focussed on the identities and host associations of weevils that feed on the fruit and seeds of plants in tropical forests.
The weevils feed on the seeds as larvae, which are very difficult to identify. Studies in forests in Thailand, Indonesia, Malaysia and Brunei have involved rearing these larvae to adults in the field.
This extensive research has lead to a database of insect seed-feeders on the Asian tree family Dipterocarpaceae and has created a valuable tool for studying the ecology and impact of weevil species on tree seeds.
To avoid having to rear larvae to maturity, since they often die, DNA barcodes have been used on Central American forest studies to associate larvae and adults.
