- Egg parasitioids are considered reliable since most of the Sevaxa eggs are laid in the soil.
- The parasitoid Stichotrema dallatorreanum is an important natural enemy, the female larvae parasitise sexava species which reduces the eggs laid by female Sexava.
In Indonesia, an entomophatogen, "Metabron" (Metarrhizium
isolated from Brontispa) was used to control Sexava spp on coconut. Metabron was applied at the concentration of 5 x 105 conidium/μl and causes approximately 90,25% nymph mortality and 86,25% imago mortality. The biological agent is advantageous as it can be maintained for a long period provided the condition is conducive.
Apart from ensuring good field sanitation, the following methods can be adopted if it is practical:
- Placement of sticky bands of gum resin at the base of the palms.
- Scrape the soil to expose eggs near the palm base.
When the population is low, hand collection can also be conducted.
