- aggregation abstract "Effects of three constant temperatures (15, 25, and 35 degrees C) on development and reproduction of Orius laevigatus (Fieber) and O. albidipennis (Reuter) (Heteroptera: Anthocoridae) and on their predation activity against the western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) were investigated in the laboratory Small rooted plants of Spanish pepper (Capsicum annuum L. cv. 'Creta', long red) served as oviposition substrate and moisture source. Survival of eggs and nymphs of both species was high at 25 and 35 degrees C. At 15 degrees C, none of the eggs of O. albidipennis hatched and the number of nymphs completing the immature stage was extremely low. Developmental time of nymphs was not significantly different between species at 15 degrees C, but at 25 and 35 degrees C nymphs of O. laevigatus took significantly longer to develop than those of O. albidipennis. Females of O. albidipennis lived longer than those of O. laevigatus at 15 and 35 degrees C, but no differences were observed at 25 degrees C. Fecundity of O. albidipennis was greatly reduced at 15 degrees C, whereas a temperature of 35 degrees C was close to the upper reproduction threshold of O. laevigatus. Fecundity was highest at 25 degrees C for both species. At 15 degrees C, the intrinsic rate of increase (r(m)) reached a minimum for both species. For O. albidipennis, the r(m)-value increased with temperature (0.121 at 25 degrees C and 0.302 at 35 degrees C), whereas for O. laevigatus it peaked at 25 degrees C (0.105) but decreased at 35 degrees C (0.051). At 15 and 25 degrees C, adults of O. laevigatus consumed more F. occidentalis adults during their total lifespan than those of O. albidipennis, but the latter showed a better predation activity at 35 degrees C; in all treatments, however, adults of O. laevigatus consumed more prey per day than did those of O. albidipennis. The performance of both anthocorids at the different temperatures is discussed in relation to their practical use in integrated pest control programmes.".
