7. Most Coccinellidae species are beneficial to agriculture, acting
as predators of aphids, fungal spores, and moth larvae.
However, a few of the Coccinellidae species are pest insects
eating pollen and even vegetables.
Among the pest Coccinellidae species, H. vigintioctopunctata is
one of the most destructive pests, causing heavy damage to
vegetable crops in some countries, principally those belonging
to the Solanaceae family (i.e., Solanum tuberosum, S.
melongena, Lycopersicon esculentum, and Lycium spp.).
Adults and larvae feed on the epidermal tissues of leaves and
fruits, resulting in considerable economic losses
