“…Flight variables (duration, distance, velocity) of 5-day-old adults were measured using a flight mill (FXMD-24-USB, Jiaduo Science Industry and Trade Co., Ltd., Hebi, China) as described previously [ 32 , 33 ]. The mesothorax was attached to the arm of a flight mill using 502 glue (Shenzhen Jinsan second Adhesive Co., Ltd., Shenzhen, China).…”

Eupeodes corollae Fabricius, as one of the most common beneficial predatory insects in agricultural ecosystems, provides pollination and biological control services that help improve crop yield and maintain biodiversity. However, systematic research is needed on the species of aphids used for propagation. To develop highly fit populations of the important insect predator and crop pollinator, E. corollae, for research and commercial use, further research is needed to develop the most nutritious diet and efficient propagation methods. Here, the fitness of E. corollae was assessed in the laboratory after larvae were fed an aphid diet of Aphis craccivora Koch, Myzus persicae Sulzer or Megoura japonica Matsumura. The larval survival rate on M. japonica was significantly lower than on A. craccivora and M. persicae. The developmental duration for larvae (7.6 d) and pupae (6.9 d) was longest on A. craccivora. The pupal emergence rate on A. craccivora (98.0%) was significantly higher than on the other two, and lowest (64.7%) on M. japonica. On A. craccivora, M. persicae, and M. japonica, respectively, the generation time was 24.85 d, 23.12 d and 21.05 d; the value for the intrinsic rate of natural increase was 0.19, 0.20, and 0.21; and the value for the finite rate of increase was 1.21, 1.22, and 1.23. For flight variables, E. corollae attained the fastest velocity and longest distance and duration on M. japonica. The M. japonica diet, thus, provided the shortest generation time, the highest intrinsic rate of natural increase and finite rate of increase, the maximum fecundity and the greatest flight ability. Thus, to improve the survival rate of E. corollae larvae, A. craccivora or M. persicae can be used to feed newly hatched larvae, and M. japonica can be used for second- and third-instar larvae. These results provide a theoretical basis for feeding E. corollae and optimizing its ecosystem services.

“…separata (Chang et al, 2018; Liu et al, 2016; Liu, Fu, et al, 2017). This result may be due to the fact that both male and female migratory noctuid moths must feed on plants to meet nutritional requirements for the development of the internal reproductive system and for energy for flight, mating, and/or oviposition and other processes (Gilbert, 1972; He et al, 2021; Wäckers et al, 2007; Wu & Guo, 1997; Zhou et al, 2019). Pollen adherence frequency on insects varies obviously among different insects; for example, 68.3% of male H .…”

“…Different food sources can affect the structure and the temporal dynamics of an insect population (Wäckers et al, 2007). The quality and quantity of food sources can influence insect survival, development, flight, and reproduction (He et al, 2021;Wäckers et al, 2007), and the fitness of insects usually differs depending on its nectar and/or pollen sources (He et al, 2021;Liu, Zhu, et al, 2017). Of course, further study is needed to explore host-plant feeding preferences of H. trifolii adults and assess the effects on population dynamics.…”

“…The food source is also likely to affect reproductive and migratory fitness. Migratory noctuid moths are often contaminated with pollen (Chang et al, 2018;Hendrix et al, 1987;Hendrix & Showers, 1992;Liu et al, 2016;Liu, Fu, et al, 2017;Zhou et al, 2019), and adult feeding (pollen or nectar) can significantly increase the longevity, flight, and reproductive capability of lepidopteran insects (Gilbert, 1972;He et al, 2021;Liu, Zhu, et al, 2017;Wäckers et al, 2007;Wu & Guo, 1997). However, it is still unclear which plant species are hosts for migratory H. trifolii moths, where the moths originate and the areas in which the moths pollinate flowers.…”

“…According to Wahyuni et al [16], food sufficiency, climate, competition, and natural enemies are environmental factors that significantly influence population growth and development, which in turn affects the natural decline in insect pest populations. Nutrient sources in the form of nectar or pollen can act as carbohydrates that can improve the fitness and reproductive output of adult Lepidoptera including S. frugiperda [17].…”

The aim of this study is to assess the extent of attack and the potential for decreased production of maize types in the field caused to Spodoptera frugiperda. This study was carried out on a large scale, with four treatments and six replications (10 systematic sample replications). Parameters observed include population development, attack rate, the potential for production decline. The results show that this pest attack began to be found in maize 2 weeks after planting (wap) with an average population of 5.37 individu on sweet corn and 6.53 individu on glutinous corn. Furthermore, the population continued to increase up to 5 wap and lowering again to 8 wap. The regression analysis revealed a positive relationship between the larval population and the S. frugiperda attack rate. Sweet corn production decreased by 28.08 percent and glutinous corn output decreased by 25.04 percent, respectively. Overall, our results showed that S. frugiperda attacks continued to increase in both maize varieties (glutinous and sweet), which was indicated by an increase in population and a decrease in production on a field trial scale.
