Abstract

A laboratory study revealed that the high intensity of light retarded the
development of the immature stages of the predatory stlgmaeid mite, Agislemus
exsertus Gonzalez. Additionally. the predatory adults showed a high photoperiodic
response. Adult longevity correlated negatively with increasing light intensity or
photoperiod. Moreover, reproduction and predation capacity of females were
negatively responded to photoperiod and light intensity.
