“…A fundamental factor influencing the biological rates of most ectotherms is the temperature (Kim et al, 2020). The impact of temperature on biological rates extends from biochemical reactions to individual physiology to nutrient cycling in ecosystems (Brown et al, 2004;Rall et al, 2012;Yvon-Durocher et al, 2012;Amarasekare, 2015;Islam et al, 2022). The temperature has the potential to modify species interaction strengths and alter energy distribution across food webs.…”

Functional responses are central to predator–prey dynamics and describe how predation varies with prey abundance. Functional responses often are measured without regard to prey size (i.e., body mass) or the temperature dependence of feeding rates. However, variation in prey size within populations is ubiquitous, and predation rates are often both size and temperature-dependent. Here, we assessed functional responses of larvae and adult Harmonia axyridis on the 1st, 2nd, and 3rd instars of the prey Spodoptera litura across a range of temperatures (i.e., 15, 20, 25, 30, and 35°C). The type and parameters of the functional responses were determined using logistic regression and fitted to the Roger's random predator equation. The magnitude of predation varied with the predator and prey stage, but prey predation increased with warming and predator age. Predation by the female and 4th instar of H. axyridis on the 1st instar of prey was greater, followed by the 2nd and 3rd instar of prey S. litura. No predation occurred on the larger prey for the 1st, 2nd, and 3rd instars of H. axyridis. The larvae and adult H. axyridis produced a type II (hyperbolic) functional response curve across all temperatures and the three prey types they consumed. Space clearance rates, handling time, and maximum predation rates of H. axyridis changed with temperature and prey size, increasing with temperature and decreasing with prey size, suggesting more predation will occur on younger prey. This study indicates an interactive role of temperature and prey/predator size in shaping functional responses, which might complicate the planning of effective biocontrol strategies against this serious pest.

“…The age–stage, two‐sex life table is a reliable tool for predicting population growth trends of arthropods and also determining the impact of various environmental factors such as humidity, temperature, and salinity on the growth capacity of insect populations (Yang et al., 2014; Quais et al., 2019; Chi et al., 2020; Ghodoum Parizipour et al., 2021; Islam et al., 2022; Tian et al., 2022). Incorporating differences between the sexes is one of the prime advantages of utilizing the age–stage, two‐sex life tables, so population projections based on them can eliminate various inherent errors characteristic of female‐based life tables (Chi et al., 2020).…”

Salinization, as one of the foremost abiotic stresses, is an intensifying problem in many agroecosystems. Climatic changes, along with altering land use and also salinity of irrigation water all lead to enhanced soil salinity in agricultural lands. Changes in plant characteristics, as a result of raising soil salinity, may impose bottom‐up impact on plant‐feeding insects. We assessed the bottom‐up impact of salinity stress on demographic traits of the western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), on cherry tomato, Solanum lycopersicum L. var. cerasiforme (Solanaceae) plants under greenhouse conditions (27 ± 2 °C, 65 ± 5% r.h., and L16:D8 photoperiod). Our results indicated that salinity stress interfered with the immature development period, adult longevity, and sex ratio of WFT. Salinity stress biased the sex ratio in favor of males. Significant concentration‐dependent differences were observed in the intrinsic (r) and finite (λ) increase rates and the net reproduction rate (R0) of WFT at different salinity levels. Salinity adversely influenced WFT development; nonetheless, population projection forecasted an ascending WFT population growth under moderate salinity stress of 100 mM (2.8 dS m−1 of NaCl), whereas severe salinity stress of 150 mM (4.7 dS m−1 of NaCl) resulted in remarkable fitness costs in WFT. This study demonstrates that WFT has the potential to become problematic in regions with moderate salinity. Therefore, it might exacerbate the detrimental impact of salinity on tomato production. The current survey provides information on the abundance of WFT on saline‐stressed tomato plants, thereby contributing to developing environmentally friendly measures to manage this notorious species in ecosystems under salinity stress.

“…Many factors that significantly determine biocontrol fate include species identity, resource quality/quantity, and other ecological considerations 9 . Temperature is primarily important for biological systems through its close link with species metabolic rates and fitness parameters i.e., survival, development, reproduction, handling time, and searching efficiency of predators 10 . Since insects are ectotherms, they rely greatly on temperature for their growth, reproduction, maturation and trophic relations 11 .…”

Biological control is one of the strategies of pest control which is determined by the biological fitness and metabolic rates of the predator species used. Temperature and resource are important factors which influence the role of insects as biocontrol agents. Harmonia axyridis is a cosmopolitan and non-specific polyphagous predator. It can survive ecologically diverse environments and exploit multiple preys. This study investigated the effects of temperature on the population parameters of H. axyridis and its predation on the eggs of prey Spodoptera litura. For this purpose, an age–stage, two-sex life table of the predator was constructed at four constant temperatures, i.e. 15, 20, 25 and 30 °C, under laboratory settings of: 70 ± 5% RH, and 16:8 h (L: D) photoperiod. A computer simulation was then used to project the population and predation responses with respect to temperatures tested. We found that the development of larvae and adult (male/female) stages of H. axyridis decreased with colder temperatures (i.e., 15 and 20 °C) but increased with warmer temperatures (25 and 30 °C). The intrinsic rate of increase (r) and mean generation time (T) were 0.0662 d−1 and 79.84 d at 15 °C, 0.0843 d−1 and 64.90 d at 20 °C, 0.1067 d−1 and 48.89 d at 25 °C, and 0.1378 d−1 and 35.55 d at 30 °C, respectively. The mean duration of the total pre-adult stage was 44.26, 32.91, 20.63, and 15.39 d at 15, 20, 25, and 30 °C, respectively. At 30 °C. the finite rate of increase (1.1477 d−1) was the highest and the mean generation time (35.55 d) was the shortest. The net predation rate (C0) was 7935.54, 10,466.28, 10,139.38, and 7126.36 eggs at 15, 20, 25, and 30 °C, respectively. Population and predation projections were proportional to temperature. These findings are important for modelling the population responses of H. axyridis to climate change and tailoring integrated pest management strategies to altered climates.
