The study was conducted at Banay-banay, Amadeo, Cavite from October 2002 to January 2003 to determine and compare the population fluctuation of arthropods at different growth stages of monocultured corn and corn intercropped with cucumber.
The insect pests that occurred in corn were seedling maggont(Atherigona oryzae Malloch), corn planthopper (Peregrinus maidis), corn semilooper (Chrysodeixis chalcites [Esper] L.), cucumber beetle (Aulacophora similes), flea beetle (Phyllotreta spp.), striped flee beetle (Phyllotreta nemorum), corn aphids (Rhopalosiphum maidis Fitch) and brown grasshopper (Family Acrididae), and longhorned grasshopper (Rhaneroptera furcufera). On the other hand, the whitefly (Bemisia tabaci), leafminer (Family Agromyzidae), cutworm (Spodoptera litura), black leafhopper (Ricinia speculum) and melon aphids (Aphis gossypii) were found attacking cucumbers. Corn planthopper was the dominant insect pest of corn. It was observed from early whorl to maturity. Cutworm and whitefly were the dominant insect pests in cucumber.
The number of beneficial arthropods was also determined. These are the spiders (Arachinida), ladybird beetle (Coccinellidae), praying mantis (Mantodea), and earwig (Dermaptera). The spiders and ladybird beetles were the dominant groups for both corn and cucumber at certain growth stages.
