“…This theory supported the present study and surprisingly showed that O. strigicollis showed a higher and similar r (faster development and highest survival rates) when fed with 10 and 15 eggs of P. gossypiella, compared to the 5-egg treatment, owing to higher fecundity and shorter or faster development times (Table 4). In addition, our study was linked with other recent studies [44,81,94,97], whose authors reported the value of r for different Orius spp. and proved that diet has an important role in the approximating of the population parameters of insects.…”

A two-sex life table is a useful tool for studying the fitness of predators. Previous studies of Orius strigicollis Poppius (Heteroptera: Anthocoridae) fitness have not been done on Pectinophora gossypiella (Lepidoptera: Gelechiidae) using a two-sex life table tool. This study reports the fitness of the minute predatory flower bug, O. strigicollis when feeding on the cotton pest P. gossypiella using a two-sex life table tool. Different densities (5, 10, and 15 eggs) of P. gossypiella eggs were used to calculate the feeding capacity and fitness of O. strigicollis in the laboratory at 28 °C ± 1, 75 ± 5% RH and 16:8 (L:D). The results concluded that O. strigicollis is an efficient predator of P. gossypiella. The maximum growth capacity of the predatory bug O. strigicollis was attained when it was fed on 10 and 15 P. gossypiella eggs. Furthermore, shorter generation and development time were also observed in the case of 15 eggs of P. gossypiella. These results suggest that O. strigicollis has considerable predatory potential and prefers feeding on P. gossypiella eggs than on the first instar larvae at the fourth instar or the female stage. Although the field potential of O. strigicollis is still unknown, this study will support future investigations in terms of field applications.

“…The linear relationship between temperature and development rate ( 1/development time ) of eggs and nymphs was described by a linear day-degree model, which has been well documented to be suitable for estimation of lower development thresholds (LDTs) and thermal constants in several arthropods ( Campbell et al 1974 , De Clercq and Degheele 1992 , He et al 2003 , Du Plessis et al 2011 , Bonte et al 2012 , Luypaert et al 2014 , Mujica et al 2017 ). The equation fitted was ‘ Y = a + bX ’, where Y is the development rate, X is the rearing temperature, and the regression parameters are the intercept ( a ), and the slope ( b ).…”

When quinoa, Chenopodium quinoa Willd., is cultivated in South America outside of its Andean origin, the heteropterans Liorhyssus hyalinus (Fabricius) and Nysius simulans Stål may emerge as important pests. Here we studied the development and reproduction of both species at different constant temperatures in the laboratory. Egg and nymphal development were investigated at 18, 22, 26, 30, 34, and 36°C. For both species, egg incubation time significantly decreased as the temperature increased. Nymphs did not successfully develop at 18°C and the total nymphal time significantly decreased as the temperature increased from 22 to 36°C. Based on a linear day-degree (DD) model, the lower developmental threshold (LDT) temperatures for eggs and nymphs were estimated to be 16.0 and 17.9°C for L. hyalinus, and 16.1 and 19.7°C for N. simulans, respectively. Thermal requirements for egg and nymphal development were 68.6 and 114.8 DD for L. hyalinus, and 77.7 and 190.3 DD for N. simulans, respectively. Reproduction and adult longevity were studied at 22, 26, 30, and 34°C. For both species preoviposition time decreased as temperature increased, and the oviposition period was longest at 26°C. The highest fecundity and egg viability were observed at 30°C, whereas longevities were higher at 22–26°C than at 30–34°C. As the lowest tested temperatures were not suitable to both heteropterans and 30°C was found to be the optimal temperature for development and reproduction, peak densities are expected in warm areas and seasons.

“…Linear models are used for calculating lower developmental thresholds and thermal constants in insects, within a range of 15 to 30°C (Bonte et al, 2012). At extremely low or high temperatures, which are deleterious to growth, the relationship between insect developmental rates and rearing temperatures cannot be explained by a straight line.…”

“…Temperature has a profound influence on the biological parameters of different species of Orius viz., Orius laevigatus (Fieber) (Alauzet et al, 1994;Cocuzza et al, 1997); O. sauteri (Poppius) (Nagai and Yano, 1999); O. strigicollis (Poppius) (Kim et al, 1999;Ohta, 2001); O. albidipennis (Reuter) (Cocuzza et al, 1997); O. insidiosus (Say) , O. thyestes Herring ; O. similis Zheng (Zhou et al, 2006;Zhang et al, 2012); O. thripoborus (Hesse) and O. naivashae (Poppius) (Bonte et al, 2012). The effect of different laboratory hosts on fertility parameters of O. tantillus has been studied by Ballal et al (2012) and of temperature on the biological parameters of O. tantillus when fed on the target pest T. palmi by Nakashima and Hirose (1997).…”

Experiments were conducted to investigate the effect of different temperature regimes (16, 20, 24, 28, 32 and 36±1°C) on the biological and fertility table parameters of Orius tantillus (Motsch.), an efficient indigenous predator of various thrips species in India Temperature influenced the development and reproduction of O. tantillus. Based on the biological parameters, viz. longevity, fecundity and fertility parameters, 24°C was recorded to be the optimum temperature for rearing O. tantillus. The temperature of 16°C had a detrimental effect on nymphal survival, while 36°C on fecundity. Thus, 16 and 36°C were recorded as unsuitable for rearing O. tantillus. The lower threshold temperatures for development of eggs and nymphs of O. tantillus were 8.66 and 6.92°C, respectively, indicating that the eggs are more heat-sensitive than the nymphs. Based on the T 0 values, O. tantillus appears to be less heat sensitive in comparison to other Orius spp. The information generated through this study could be used for further improving the standardized production protocol for O. tantillus and also for planning and timing field releases to target thrips species.
