A wild-type colony was maintained without introgres-sion for 5+ years in the Stoneville Research Quarantine Facility (SRQF) in Mississippi. Insect stocks were kept in an environmental chamber (Percival Scientific, Inc. Perry, IA) set for 16:8 (L:D) h lighting regime with 25°C daytime and 19°C nighttime temperature and 55%RH. Insects were provided a standardized diet and oviposition system based on NI diet and 4% gelcarin oviposition substrate [55].
