Without Stem Boring Grub Stem boring grub zone
The sugarcane stem boring grub (SSBG), Dorysthenes buqueti Guerin is one of major sugarcane insect pest in northeastern Thailand. SSBG become a serious sugarcane insect pest. It can cause more than 70% yield loss in outbreak area. This insect pest attack sugarcane plant by the larval stage into the ratoon or base of stalk tissue inside which results the whole plant turned brown and die.

Sugarcane Famer solve the problem by adult trapping for make food. But also we need to control insect in larva stage because cause high sugarcane damage.

First step, Metarhiziuum conidia germinate on the host surface and differentiate the infection structure termed appressorium. Then, the appressorium penetrates the cuticle and enters the haemocoel. Then hypal bodies and the potential toxin produced lead to the insect death. 25 MITR PHOL INNOVATION AND RESEARCH CENTER Evaluation of entomopathogenic fungus Metarhizium anisopliae for controlling Dorysthenes buqueti Sugarcane Stem Boring Grub (SSBG)
