“…Kang and Krupke (2009a) conducted laboratory studies on western corn rootworm that demonstrated that males averaged less than three matings in the 3 wk after they Þrst mate (far fewer than the 8.2 times reported by Branson et al 1977), and the majority were no longer competent for mate-seeking beyond those 3 wk. Given the multiweek delay in adult emergence from refuge versus transgenic hybrids in block plantings, these data suggest the realized mating activity between susceptible refuge males and potentially resistant transgenic-Þeld female may be quite low.…”

The use of mixtures of transgenic insecticidal seed and nontransgenic seed to provide an in-field refuge for susceptible insects in insect-resistance-management (IRM) plans has been considered for at least two decades. However, the U.S. Environmental Protection Agency has only recently authorized the practice. This commentary explores issues that regulators, industry, and other stakeholders should consider as the use of biotechnology increases and seed mixtures are implemented as a major tactic for IRM. We discuss how block refuges and seed mixtures in transgenic insecticidal corn, Zea mays L., production will influence integrated pest management (IPM) and the evolution of pest resistance. We conclude that seed mixtures will make pest monitoring more difficult and that seed mixtures may make IRM riskier because of larval behavior and greater adoption of insecticidal corn. Conversely, block refuges present a different suite of risks because of adult pest behavior and the lower compliance with IRM rules expected from farmers. It is likely that secondary pests not targeted by the insecticidal corn as well as natural enemies will respond differently to block refuges and seed mixtures.

“…Unmated females can release pheromone and call for males for at least 3 d (Hammack 1995). Most females cease calling for males within 24 h of insemination (Hammack 1995), and insemination causes most females to be either unattractive or unreceptive to males (Hill 1975, Branson et al 1977. The protandrous adult males emerge earlier than the females and thus are ready to mate as soon as females emerge (Quiring and Timmins 1990).…”

“…The protandrous adult males emerge earlier than the females and thus are ready to mate as soon as females emerge (Quiring and Timmins 1990). Branson et al (1977) observed that males could mate an average of eight times during a 42-d period; however, Quiring and Timmins (1990) found that males can mate up to 17 times during their lifetimes.…”
