Diabrotica undecimpunctata undecimpunctata
Western Spotted Cucumber Beetle
The western spotted cucumber beetle is a polyphagous leaf beetle native to western North America. It is a significant agricultural pest of cucurbits, snap beans, corn, and other crops, with larvae feeding on roots and adults feeding on foliage, flowers, and fruit. Unlike the eastern subspecies, it does not vector bacterial wilt in cucurbits. Adults are strong fliers and readily disperse between fields.
Myllocerus
oriental broad-nosed weevils, ash weevils, grey weevils, Sri Lankan weevils
Myllocerus is a large genus of oriental broad-nosed weevils in the family Curculionidae, comprising at least 330 described species. Species within this genus are predominantly distributed across the Indian subcontinent and surrounding regions, with several species recognized as significant agricultural pests. Notable pest species include Myllocerus undecimpustulatus undatus (Sri Lankan weevil), M. maculosus (cotton grey weevil), and M. viridanus (ash weevil), which attack diverse crop plants including cereals, legumes, vegetables, and fruit trees. The genus exhibits typical weevil morphology with broad rostrums and root-feeding larval stages combined with foliage-feeding adults.
