abstract: Crop monitoring was undertaken in October 2001 to evaluate the importance of insect pests in various counties in Guangxi and Hainan provinces. At Guangxi Academy of Agricultural Sciences research station, plants at the vegetative stage, especially the determinate types, were severely attacked by Maruca vitrata (10-12 webs per plant). Podfly and aphids were also noticed in early-maturing types; however, the damage level was only secondary. At Tiandeng, pigeon pea cultivars ICP 7035 and ICPL 87091 at the peak reproductive phase, sown on hilly slopes (approximately 200 m above the village), were infested with M. vitrata (10 larvae per plant) and Helicoverpa armigera (3-4 larvae per plant). Other insects, such as Mylabris spp., Euproctis sp., and Lamprosema sp., were of minor importance. In Taipin, Wuming, damage caused by mealy bugs and podfly was not economically important (<5% damage). At Manjiang, the presence of insects such as Maruca, semilooper, Exelastis atomosa, Helicoverpa, and Clavigralla sp. on pigeon pea grown after maize was not economically important at the time of observation. Maruca and Helicoverpa spp. were starting to infest seed production plots at Pinguang, Fengcheng, during the observation period. At Fushan, Hainan, germplasm evaluation plots were severely infected with yellow mosaic and sterility mosaic viral diseases. Infestation by Oxya, Maruca, and Helicoverpa spp. was also observed. Maruca infestation, which was more serious in determinate types of pigeon pea, was also evident in neighbouring Psophocarpus tetragonolobus.
