Because plant bugs and stink bugs continue to pose a challenge to current and future efforts concerning cotton insect management, we continued investigations into alternative monitoring strategies and management tactics for the pest complex. Research with treatment thresholds for plant bugs, based on sampling insect density, supported treatment at 1 bug/3 row feet. In laboratory bioassays concerning insecticide efficacy, methyl parathion (Methyl 4E) and dicrotophos (Bidrin 8) provided superior control (100% mortality) of field-collected fifth instars and adults of the green stink bug (GSB), Acrosternum hilare (Say), and the southern green stink bug (SGSB), Nezara viridula (L.), and very good control (86 and 91%, respectively, 24-hr mortality) of the redbanded stink bug* (RBSB), Piezodorus guildinii (Westwood). Pyrethroid insecticides alone provided variable control (73-100%, 24-hr mortality) of GSB and SGSB and poor control (33-73%) of RBSB. In caging experiments with GSB and bolls of varying age, results were inconsistent with those found previously. [ABSTRACT FROM AUTHOR] |
