Influence of Stake and Mulch Culture on Lepidopterous Pests of Tomato
Abstract
Response of various lepidopterous species to staked and artificially mulched culture of tomatoes was evaluated by counting numbers of pests and by examining damage to tomato foliage and fruit. Granulate cutworm, Feltia subterranea (Fab.), numbers and injury to fruit were less in early spring on plants grown on black polyethylene-coated paper mulch. Numbers of granulate cutworms, southern armyworms, Spodoptera eridania (Cramer), and a complex of less abundant noctuid larvae were inhibited by staking. Damage by all species was also reduced in staked plants. Insecticidal sprays applied to staked plants resulted in increased leafmining by tomato pinworms, Keiferia lycopersicella (Walsingham).Downloads
