Abstract

The population dynamics of arthropod pests of eggplant was studied for two years (two dry season and two wet season plantings) in Batangas and Pangasinan. Occurrence of major pests in the two sitios were similar except that populations in Pangasinan were always several folds higher than those in Batangas. Four major pests occurred regularly at high population levels during the dry season, namely Amrasca biguttula, Bemisia tabaci, Leucinodes arbonalis and Thrips palmi. The rest had more or less occasional or sporadic occurrences. Some species were abundant in at least one trial like Aphis gossipii, flea beetles, Spodoptera litura, chrysodeixis criosoma and Liriomyza spp. or other species like phytophagous mites were favored by dry condition. Only L. orbonalis was found abundant in Batangas while this species and Epilachna were abundant in Pangasinan during the wet season. The implication of population dynamics of these pests to pest management is discussed.
