Rate of consumption, biological parameters, and population growth capacity of Orius laevigatus fed on Spodoptera exigua

Using a Two-Sex Life Table Tool to Calculate the Fitness of Orius strigicollis as a Predator of Pectinophora gossypiella

“…The fitness and population, or life table parameters, were determined with the help of the age-stage, two-sex life table tool that efficiently explains the aspects of the prey range on the fitness and development of the predators [11,14,57,58]. Selection pressure is a barrier for the decision of suitable, favorable, or reliable sources of food for insects to complete their entire development or life stages, and the survival of future generations [11][12][13][14]. In this experiment, the selection pressure was provided to the predatory stages of O. strigicollis in the form of limited or excessive food (5, 10, and 15 eggs), and the alternate effects of this pressure on the entire generation was determined.…”

“…The stems with eggs laid by the O. strigicollis female were kept in plastic containers and were placed in a chamber as described above, to check their biological or fitness parameters after each treatment following previously described methods [30,[61][62][63]. These parameters were greatly influenced by the selection pressures on the predators, to continue the next generation or suppress the pest population dynamics successfully [10][11][12][13]59,64]. The number of O. strigicollis hatched eggs were recorded daily using a stereomicroscope.…”

“…However, there are many factors that affect the fitness traits of predators such as prey quality, density and temperature [10,11]. Voracious or keen prey is also an important factor [11][12][13][14] that affects the development or fitness of predators [9,[15][16][17][18][19][20][21].…”

“…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 global invasion by the thrip, Frankliniella occidentalis: Current virus vector status and its management

“…The macrobials currently being widely and effectively used are anthocorid bugs ( Orius spp.) (Mo et al ., ; Aragón‐Sánchez et al ., ), green lacewing species (Sarkar et al ., ) and predatory phytoseiid mites (Messelink et al ., ; Ahmed & Lou, ), which predominantly attack 1st instar thrips on foliage, and soil‐dwelling predaceous laelapid mites (Berndt et al ., ; Wu et al ., ), which consume thrip pupae in soil.…”
