“…This is the first study to report T. grandis parasitism at a wide range of temperatures and enabled us to develop a parasitism model for T. grandis. For this reason, and because the fecundity of solitary parasitoids is equal to its potential, I used the Curry & Feldman (1987) method to express parasitism, an approach that has been applied to construct an oviposition model for many arthropod pests (Kim & Lee, 2003a;Kim & Lee, 2003b;Marchioro & Foerster, 2012;Pakyari et al, 2012;Kim et al, 2013;Kang et al, 2015;Pakyari et al, 2016;San Choi & Kim, 2016 ;Baek et al, 2017;Lee et al, 2018;Noor-ul-Ane et al, 2018;Choi et al, 2020;Farazmand & Amir-Maafi, 2020;Park & Lee, 2020;Geng et al, 2021;Noor-ul-Ane & Jung, 2022). In the present study, T. grandis can develop its population at least at temperatures from 15 to 37.5 °C and showed interesting biological traits at different temperatures.…”

Trissolcus grandis Thompson (Hymenoptera: Scelionidae), a native Sunn pest egg parasitoid in Iran, has the potential as a biological control agent for sunn pest, Eurygaster integriceps Puton (Het.: Scutelleridae). However, its ecological characteristics have remained unclear. Thus, this study aimed to develop a parasitism model of T. grandis with sunn pest egg as host. In order to obtain the data for the model, the longevity, survivorship and parasitism capacity of the adult female T. grandis were examined at nine constant temperatures (15, 17.5, 20, 25, 27.5, 30, 32.5, 35, and 37.5 ± 0.5 °C), relative humidity 65 ± 5% RH, and a photoperiod of 16:8 (L:D) h. Longevity (mean±SE) decreased as temperature increased and was the longest at 15°C (73.18 ± 3.86 days) and the shortest at 35°C (18.98 ± 0.48 days). A modified model of Sharp-DeMichele well described adult developmental rate (1/mean longevity) in the range of studied temperatures (r 2 = 0.994) and was used to calculate the physiological age. The mean total host eggs parasitized/female (mean ± SE) was greatest at 17.5°C (275.84 ± 3.21 host eggs) and lowest at 15°C (25.06 ± 3.221 host eggs). The temperature-dependent total parasitism, the age-specific cumulative parasitism rate, and the agespecific survival rate were best described by an extreme value function (r 2 = 0.934), the twoparameter Weibull function (r 2 = 0.967), and a sigmoid function (r 2 = 0.979), respectively. I anticipate that the fitted models and parameters may be useful in developing a population model for T. grandis and lead to a better understanding of its parasitism strategy.

“…6 For our study, we opted for the rate summation method, which has demonstrated satisfactory results in numerous recent publications involving various insect species. 6,7,28,29,[39][40][41] Our oviposition model comprises four key components: senescence rate, total fecundity, age-specific oviposition rate, and age-specific survival rate. Under field conditions, daily air temperature data collected from ground-based weather stations or weather satellites can be used as input to calculate the senescence rate and total fecundity.…”

“…In this study, the adult senescence rate, calculated as the reciprocal of female median longevity in days, was modeled as a function of temperature utilizing the model polynomial equation:

r (T) = a + bT + c T^{2}

where r(T) denotes the senescence rate at temperature T (°C) and a , b , and c are fitted parameters. This particular equation was chosen by considering that polynomial functions accurately described the relationship between senescence rate and temperature in previous studies 28,29 …”

BACKGROUNDTemperature plays a critical role in the development and reproductive process of insects. Therefore, understanding how insects respond to temperature is vital for comprehending and predicting their population dynamics, particularly when it comes to agricultural pests. Spodoptera eridania Stoll is a polyphagous pest that has recently expanded its distribution beyond its native range. In this study, we assessed the impact of temperature on the reproduction of S. eridania and used the obtained data to develop an oviposition model that could be used to predict egg‐laying behavior under field conditions. The reproductive parameters were evaluated at temperatures of 15, 20, 25, 28, and 32 °C.RESULTSTemperature had a significant impact on the reproductive parameters examined. Overall, as temperature increased, the pre‐oviposition period, oviposition period, and longevity decreased. Total fecundity exhibited a bell‐shaped response to temperature, with peak egg‐laying observed at 20 and 25 °C. In line with the experimental data, our model predicted higher rates of oviposition between 20 and 26 °C, thus reinforcing that this temperature range may represent the optimal conditions for the reproduction of S. eridania.CONCLUSIONThe findings from our study provide a significant contribution to the understanding of the ecology of an important agricultural pest. The information generated can have practical applications in developing control strategies by enabling the aligning of the timing of control measures with peaks of reproductive activity.This article is protected by copyright.

Two-Sex Life Table Analysis of the Predator Arma chinensis (Hemiptera: Pentatomidae) and the Prediction of Its Ability to Suppress Populations of Scopula subpunctaria (Lepidoptera: Geometridae)

Scopula subpunctaria (Herrich-Schaeffer) (Lepidoptera: Geometridae) is a leaf-eating pest in tea plantations that often causes serious economic losses. Arma chinensis (Fallou) (Hemiptera: Pentatomidae) as a polyphagous insect has become one of the main biological control agents for tea plantation pests due to its wide feeding habit, predatory ability, and adaptability. However, studies related to the predation using A. chinensis on the third instar S. subpunctaria have not been reported. In this study, we used the age-stage, two-sex life table method to analyze the developmental duration and fecundity of S. subpunctaria fed on tea, and A. chinensis fed on third instar S. subpunctaria larvae, under a 25 °C regime. The growth, development, survival, fecundity, and predation rates of the insect populations were investigated. The results showed that the predator and the prey can complete their respective life histories, but the developmental durations at each stage were different, and the developmental stages overlapped significantly. In addition, we used the computer program TIMING-MSChart to project the stage structure and the total population size of A. chinensis and S. subpunctaria. We also simulated the population changes of S. subpunctaria using an A. chinensis intervention. These results showed that S. subpunctaria can support A. chinensis to finish its life history and A. chinensis has great potential to control S. subpunctaria. This study contributes to the understanding of the biological characteristics of S. subpunctaria and provides a theoretical basis for releasing A. chinensis in the field to suppress S. subpunctaria.
