Antitrogus consanguineus

Antitrogus consanguineus is a significant pest belonging to the order Coleoptera and the family Scarabaeidae. This species is widely recognized for its negative impact on commercial sugarcane plantations, where it acts as a primary root-feeding pest that compromises crop health and productivity.

The damage is primarily caused by the larvae, commonly known as white grubs, which reside in the soil profile. They feed extensively on the root systems of host plants. The presence of these larvae in high densities often leads to significant stand loss, forcing farmers to implement rigorous management protocols to mitigate potential yield declines.

The biology of this species encompasses a complex life cycle, typically spanning one to two years depending on the environmental conditions. Adults emerge from the soil to mate and feed on foliage, while the subterranean larvae undergo multiple instars, significantly impacting the subterranean biomass of the crop during their development stages.

The harmful effects are characterized by root pruning, which severely hinders the plant's ability to absorb water and essential nutrients. As the root system is destroyed, the plants display signs of yellowing, severe stunting, and reduced resistance to environmental stress, frequently resulting in patchy fields and economic loss.

• Application of soil insecticides during planting or ratoon management.
• Implementation of strategic crop rotation to reduce larval population.
• Use of entomopathogenic fungi as a biological control agent.
• Monitoring adult flight activity using light traps to time insecticide applications.
• Proper soil preparation and cultivation practices to disrupt larval habitats.
