What are the control methods for ginseng click beetles?
The insect's scientific name is the click beetle, also known as wireworm, jinci rake, yellow youyan, etc., and its adult is also called the snapping beetle. It belongs to the order Coleoptera, family Elateridae. It causes the most serious damage to ginseng. It generally begins activity after the soil thaws, and the larvae mainly damage the underground root and stem parts of ginseng, generally in the layer from the ginseng root to 10 cm below the surface...
The insect's scientific name is the click beetle, also known as wireworm, jinci rake, yellow youyan, etc., and its adult is also called the snapping beetle. It belongs to the order Coleoptera, family Elateridae.
Damage: It causes the most serious damage to ginseng. It generally begins activity after the soil thaws, and the larvae mainly damage the underground root and stem parts of ginseng, generally in the layer from the ginseng root to 10 cm below the surface, with the vast majority causing damage at 5-8 cm.
Life habits: The click beetle often requires 3-5 years to complete 1 generation, overwintering as larvae of various instars and adults. The click beetle relatively prefers low temperatures and cannot tolerate high temperatures. In spring, when the soil temperature at 10 cm underground reaches 9°C, it begins activity. In summer, when the soil temperature reaches above 22°C, the larvae burrow into the soil to oversummer, and generally early June to mid-July is the peak period of damage to ginseng.
Control: The click beetle generally begins causing damage when the soil temperature is 9°C, so it is best to apply pesticide during this period. Apply 15% abamectin.chlorpyrifos (1000G) per generation to 6-7 bed furrows or scatter it on the bed surface, then use a rake to rake it 3-5 cm into the ground; or use Dianzhen (Kuangshan) at 7-8 beds per bottle, spray it on the bed surface before rain, and let it enter with the rainwater.
