Coelophora biplagiata

Systematic position: Coelophora biplagiata belongs to the order Coleoptera and the family Coccinellidae. While many members of this family are recognized as predators, Coelophora biplagiata is known for its herbivorous habits, causing direct damage to plant tissues in various agricultural and horticultural settings.

Host crops: This pest primarily affects tropical and subtropical crops, including various citrus species and tea plants. It has also been documented on several ornamental plants and legumes. The preference for specific hosts often depends on the geographic distribution and the availability of succulent vegetation during the growing season.

Biology and life cycle: The life cycle involves complete metamorphosis, consisting of the egg, larval, pupal, and adult stages. Adults are typically active throughout the day, feeding on plant surfaces. After mating, females lay clusters of eggs on the underside of leaves. Larvae are the most active feeding stage, causing significant damage as they grow rapidly before reaching the pupal stage.

Damage patterns and economic importance: Both adults and larvae consume leaf tissue, creating irregular holes and skeletal patterns. This feeding activity reduces the total leaf surface area available for photosynthesis, leading to stunted growth, loss of vigor, and reduced yields. In severe infestations, the damage can lead to premature leaf drop and increased susceptibility to secondary plant pathogens.

Control measures: Management of Coelophora biplagiata focuses on integrated pest management (IPM) practices:

• Regular field monitoring to detect early populations and prevent outbreaks.
• Application of biological control agents where applicable.
• Use of selective insecticides that minimize impact on non-target beneficial species.
• Maintaining field hygiene by removing crop debris that may harbor pupae or overwintering adults.
