Selenisa Sueroides (Lepidoptera: Noctuidae): a Pest of Subcanopy Irrigatrion Systems in Citrus in Southwest Florida
Abstract
Mature larvae of Selenisa sueroides (Guenee) damaged micro-sprinkler irrigation systems in three citrus groves located in Hendry Co., Florida during October and November 1987. After completing development on fabaceous food plants, American jointvetch, Aeschynomene americana L., or phasey bean Macroptilium lathyroides (L.) Urban, larvae left the host plants, climbed nearby irrigation sprinklers, and chewed holes in the flexible polyvinylchloride tubing. Larvae then entered the tubing and pupated. Damage to sprinklers and connecting tubing resulted in additional grove costs that averaged $797 per site (range, 50 to $1,500). The level of damage within each grove was related to the abundance and distribution of host-plants, larval population levels, sprinkler type, and grove cultural practices.Downloads
