Effect of sublethal propoxur exposure on male German cockroaches (Orthoptera: Blattellidae) and their feeding behavior.
Exposure of male German cockroaches, Blattella germanica L., to propoxur produced significant water loss at 2 and 24 h after treatment. This effect was dependent upon the state of hydration before insecticide exposure. Hydrated males lost as much as 10% of their total body mass in the form of water; dehydrated males lost about 4.3%; and untreated controls lost approximately 1.8% during the same time period. No significant compensatory feeding responses were observed 1-4 d after treatment. Water depletion associated with propoxur exposure resulted in increased water consumption for the first 2 d after treatment and then reached a plateau for the duration of the study. Males consumed water daily regardless of insecticide exposure.
