Description
The objectives of this continuing research are to make a general survey of the insect populations occurring on tropical forage plants in South America and to identify the most important pests. To realize this investigation, pure stand plots 5 X 5 m were sampled every 14 days during 2 years using a D-Vac. Vacuum Sampler.
The following information was obtained:
• Most important families and/or genera of insects in tropical forage legumes and grasses. • Insect group frequency for each season. • Insect group frequency for each plant ecotype under study. • Preliminary data on insect preference. • Preliminary data on relationships between insects on forage plants and viral, fungal, and bacterial diseases. • Most important pests of tropical forage plants in South America.
The important pests of tropical forage legumes include stemborer (Caloptilia sp.), leafhoppers (Cicadellidae, several genera), and leafeating beetles (Crisomelidae, several genera). Chinchbug (Pentatomidae, Lygaeidae) and sucking planthoppei:s (Membracidae) are under investigation as disease vectors; seed-eating beetles (Curculionidae) and budworms (Stegasta bosqueella) reduce seed production. In grasses, spittlebug (Zulia, Aeneolamia, and Deois spp.) causes serious damage, and seed-feeding leafhoppers (Cicadellidae) reduce seed production. This ongoing research provides essential information about the most important insect pests, pests of secondary importance, potential pests, and beneficial insects of tropical forage plants in five countries in South America. This is the first complete study of the insect fauna of tropical forage plants, so it is an important one.
