The Forcipomiya taiwana is one of the most annoying blood-sucking midge in Taiwan.  Synthetic pesticides are the most common strategy for controlling this pest, however, little success has been reported.  We have developed several natural products to target the immature stages (egg to pupa stage) of F. taiwana to suppress its population density in a persistent and sustainable manner.

We have developed several natural products that could either inhibit the melanization of Forcipomyia taiwana eggs, made it infertile or prevent the growth of algae, which is the food for the F, taiwana.  Moreover, several predators or parasites could act as natural enemy for F, taiwana.  All the agents could efficiently suppress the population of F, taiwana in a persistent and sustainable manner.

Natural products for F. taiwana control mentioned in this technique are available easily with low cost and need no special technology, except ants rearing. However, mass rearing of ants are achievable and easy to scale up in bio-industry with slightly improved the current rearing environments.  This technique is also transferrable to other agricultural pests with economic feasibility and return.
