Effects of spirodiclofen on life history traits and population growth of a spider mite predator <i>Oligota flavicornis</i> (Coleoptera: Staphyllinidae) based on the age‐stage two‐sex life table theory

The Hawaiian flower thrips, Thrips hawaiiensis (Morgan), a common flower-inhabiting thrip, is now a potential pest globally. Effective control of T. hawaiiensis requires information about the effects of temperature on its ontogeny and population growth. In this study, the life history characteristics and demography of T. hawaiiensis were defined at eight temperatures (9–35°C). Additionally, the thermal constant and temperature threshold were estimated by regression analysis. The developmental duration and longevity of T. hawaiiensis decreased with an increase in temperature between 16°C and 32°C; females survived for longer than males at all temperatures. The lower temperature threshold and thermal constant of preadult T. hawaiiensis were 10.5°C and 132.5 degree-days, respectively. The oviposition days of the females gradually decreased from 16°C to 32°C, and net maternity was higher at 20°C than at 16°C, even though the same number of eggs were laid at both temperatures. The mean longevities of the populations were greatest at 20°C; the life expectancy and reproductive value decreased with temperature. The intrinsic rate of increase and finite rate of increase were significantly highest at 20°C, 25°C, and 30°C. Population growth was triggered at 12.3°C, and reached a peak at approximately 27°C when it proliferated to the largest population size. Therefore, the results suggest that although the population of T. hawaiiensis starts to grow at lower temperatures, it adapts to a wide range of temperatures, and these findings facilitate prediction of different stages of damage, population size, and seasonal occurrence of T. hawaiiensis.

Effects of spirodiclofen on life history traits and population growth of a spider mite predator Oligota flavicornis (Coleoptera: Staphyllinidae) based on the age‐stage two‐sex life table theory

Abstract: A proper combination of the O. flavicornis and spirodiclofen to control the spider mite, while avoiding the side effect of spirodiclofen, could be achieved based on the knowledge of life tables. This article is protected by copyright. All rights reserved.
