“…Among them, voracious prey is one of the most important factors [11][12][13][14], which contributes considerably to the biology or fitness, physiology, fecundity, longevity, behavior, survival, and feeding efficiency of predators [9,15,16,21]. To evaluate the fitness and potential of a predator to tackle agricultural pests, feeding or predating potential rates are an important constraint [33,34,59]. For these studies, two-sex life tables provided the basic and vital information for the ecological and biological approaches, as compared to the traditional life tables.…”

“…The best predator must have the ability to survive on availability of the prey [31]. There is, however, a high level of selection pressure on predators for prey quality and density, suitable environments for oviposition, and availability of antagonists [12,13,[32][33][34]. Therefore, in complex ecosystems, each species intermingles with other species in many ways such as predatory, parasitic or mutualistic and competitive [35].…”

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.

“…Newly hatched O. sauteri were randomly assigned to feed on (i) no food or water, (ii) water but no food, (iii) water and honeydew, (iv) water and approximately 50–55 eggs of S. cerealella , or (v) water alongside eggs of S. cerealella coated by honeydew. Eggs of S. cerealella are often used in the laboratory and for commercial rearing of many species of predatory pirate bugs including O. sauteri and are considered a high‐quality food source . The oligophagous feeding habit of pear psyllids makes it difficult to maintain a large colony in the laboratory; therefore, we used S. cerealella eggs as a proxy for pear psylla nymphs in feeding experiments.…”

Background Honeydew is valuable food source for predators that can build predator numbers and strengthen biological control. Honeydew excreted by hemipterans often supplements the diets of their predators and parasitoids. However, dense sticky honeydew also creates a difficult foraging environment, potentially limiting predator efficiency. Results We examined the benefits and costs of honeydew excreted by the pear psylla (Cacopsylla chinensis [Yang and Li]) for its key predator in much of Asia, the anthocorid bug Orius sauteri (Poppius). We found these predators spent more time foraging and laid more eggs in the presence of psyllid honeydew compared to the control. However, predators more often foraged among psylla without honeydew than those coated in honeydew. This suggests that while O. sauteri recognized honeydew as a useful cue to prey presence, the predators were more likely to attack pear psylla lacking the sugary excretion. In foraging trials, honeydew consistently reduced the number of psyllids killed by the predator, suggesting it limited O. sauteri mobility or reduced the nutritional value of psyllids as prey. We also found slowed development, reduced longevity, and reduced fecundity of O. sauteri reared on moth eggs (Sitotroga cerealella [Olivier]) coated in honeydew compared to those reared on moth eggs alone. Conclusion Altogether, our results suggest that psyllid honeydew could serve as a prey‐location and oviposition cue for O. sauteri. However, honeydew also limited predator foraging with the potential to limit biological control. More generally, honeydew might form an important type of defense for stationary feeders like psyllids. © 2019 Society of Chemical Industry

“…The third instar nymphs and three-day old adult females of O. strigicollis were collected from the insectaria and fed third instar nymphs of B. tabaci and T. vaporariorum for 48 h separately and starved for 24 h. The predatory bugs were then individually transferred to small petri dishes (9 cm in diameter and 2 cm in depth) and supplied separately with third instar nymphs of B. tabaci and T. vaporariorum with different densities (4, 6, 8, 10, 12, and 14) per predator. After 24 h, predators were removed, and the prey consumed by both life stages of O. strigicollis counted under stereomicroscope (Liu et al, 2018). Bugs were used once only.…”

Background The polyphagous predatory bug O. strigicollis is an active predator used to control thrips and aphids. The whitefly species Bemisia tabaci and Trialeurodes vaporariorum are voracious pests of different economic agricultural crops and vegetables. Method In this study, the Holling disc equation and the age-stage, two-sex life table technique were used to investigate the functional response and biological traits of third instar nymphs and adult female O. strigicollis when presented third instar nymphs of both whitefly species as prey. Results The results showed a type II functional response for each life stage of O. strigicollis when fed each whitefly species. The calculated prey handling time for different O. strigicollis life stages were shorter when fed T. vaporariorum than when fed B. tabaci nymphs. In contrast, the nymphal development of O. strigicollis was significantly shorter when fed B. tabaci than T. vaporariorum nymphs. Additionally, the total pre-oviposition period of adult females was statistically shorter when fed B. tabaci nymphs than T. vaporariorum nymphs. Furthermore, the survival rates and total fecundity of O. strigicollis were higher when fed B. tabaci than T. vaporariorum. There were no significant differences in any population parameters of O. strigicollis when fed either whitefly species. These results show that O. strigicollis could survive and maintain its populations on both species of whitefly and could therefore serve as a biological control agent in integrated pest management (IPM).
