Resource Manual on IPPM in Vegetable World Education Philippines, Inc. Lady Beetle (Hippodamia convergens) The lady beetle feeds mainly on aphids and other soft-bodied insects, such as mealybugs and spider mites. Green lacewing larvae (Chrysopa carnea) Lacewing larvae, known as aphid lions, feed on insect eggs, aphids, spider mites, thrips, leafhopper nymphs, and small caterpillar larvae. Adult lacewings are not predacious. Predatory mites (Phytoseiulus persimilus)- Predatory mites and several other species feed on many mite pests, including the twospotted spider mites. Trichogramma wasp (Trichogrammatidae) tiny wasps attack eggs of more than 200 pest species, including cutworms, corn borers, corn earworms, armyworms, coding moths, and cabbage moths. The release time of trichogramma wasps is critical for their effectiveness since they only attack pest eggs. Encarsia Formosa (Encyrtidae) The greenhouse whitefly is parasitized by this wasp in third and fourth larval instars when Encarsia Formosas lay their eggs inside the whitefly scale. PREDATORY ARTHROPODS Arthropod predators make up the most numerous and widely diverse group of natural enemies of insects associated with vegetable and soybean. Many species of predators are active only at night while others actively search the foliage of crops during the day. Most predators feed on a wide variety of insects but some are quite specific. Generalist predators make up the most important group of natural enemies in most cultivated crops and are seriously affected by chemical insecticides. Name: Paederus fuscipes Curtis Family: Staphylinidae Order: Coleoptera 122
Resource Manual on IPPM in Vegetable World Education Philippines, Inc. The small (10mm) red and black beetle is common in all cultivated ecosystems in the tropics and feeds on eggs and other soft-bodied insects. It moves quickly over the foliage and often drops from the plants when disturbed. Name: Philonthus sp. Family: Staphylinidae Order: Coleoptera The staphylinid is larger (12-14 mm), less abundant and less colorful than Paederus fuscipes. Ladybeetles are abundant members of the community of predatory insects that are common to vegetable and soybean fields in Southeast Asia. With few exceptions, adults and larvae are predaceous. There are a number of species that can be identified by their distinct color patterns. However, color patterns may be quite variable in some groups. Ladybeetles feed on aphids, eggs of lepidopterans and other small soft-bodied insects. They may also use pollen and nectar as sources of energy. Name: Micraspis lineate (Thunberg) Family: Coccinellidae Order: Coleoptera This brightly colored orange and black ladybeetle (5 mm) can be abundant in soybean and mungbean. They are often seen feeding on nectarines of mungbean. Name: Coccinella transversalis F. Family: Coccinellidae Order: Coleoptera The larvae within this group are brightly colored yellow and black. Members of this group are larger than Micraspis, however, the behavior and biology of both genera are quite similar. Color patterns may be somewhat variable as with many other ladybeetles. 123
