“…It is evident that insect dispersal is affected by meteorological parameters, particularly wind, which plays a crucial role in the migration of aphids (Ghosh et al, 2019). Similarly, dos Santos et al (2021) found temperature, photoperiod, relative humidity, and wind speed had no impact on the density of thrips Frankliniella schultzei Trybom (Thysanoptera: Thripidae).…”

“…To test the correlation between the total number of aphids and weather conditions data of three sites were pooled in the same model and linear regression analysis was used. We set out 15 linear regression models based on model weights derived from information criteria, and the best model was defined according to the lowest Akaike information (dos Santos et al, 2021; Johnson & Omland, 2004), using the package “MuMin” and function model.sel (Bartoń, 2020).…”

1. Parasitoids represent the third trophic level in plant-insect food webs. They develop in or on herbivorous insects at the second trophic level, which in turn feed on plants that constitute the first trophic level. This food web system might be affected by agricultural landscape and practices.2. We studied the phenology and population density of Aphis fabae (Hemiptera: Aphididae) and determined the impact of parasitoids in organic fields of beans and beet plants.3. Twenty leaves per field were collected weekly. For each leaf, the total number of aphids, apterous and alate morphs, the number of mummies, and mortality of aphids were recorded.

“…The pest control programme based on management zones reduces the wrong decisions, showing more accuracy than the other methods evaluated in this study. Besides that, previous studies reveal that thrips populations in soybeans do not seem to vary depending on the characteristics of the host plant, nor biotic and abiotic factors, being affected only by rain and photoperiod (Santos et al., 2022). This makes thrips a suitable species to qualify for a study to control based on management zones.…”

In precision agriculture, sub‐areas of fields with similar features are called management zones and the inputs applied similarly in these zones. Such notion of management zones is applicable to high‐output soybean fields where thrips are an emerging problem leading to losses up to 15%. Management zones are an agricultural management strategy that can be used for decision‐making for controlling thrips on soybean fields. Thus, a 2‐year study was carried out on commercial soybean fields aimed at developing a decision‐making system for controlling soybean thrips using management zones. Three control programmes were established and assessed: Cl‐conventional control with insecticide use in the entire field; IPM‐CS‐conventional sampling plan + spray upon reaching the economic injury level (EIL; 3.43 thrips/sample); and IPM‐MZ‐spraying only specific areas of the field where thrips density reached the EIL. The decision to control reached using the IPM‐CS and IPM‐MZ programmes was 3× lower than those of the CI, which incurred in 75% mode decision mistakes. Furthermore, the decision to spray insecticides based on analysis of data for Cl was also incorrect. In 8.5% (3.6% of treated and 4.9% of non‐treated) of the field, the decisions of the IPM‐CS programme were incorrect. The total cost of the Cl programme (US$ 11.4/ha) was higher than that of the IPM‐CS and IPM‐MZ programmes (US$ 3.2 ha−1). Therefore, owing to its technical, economic, and environmental advantages, the establishment of management zones seems worthy of incorporation in integrated thrips management decision‐making systems for soybean fields.

“…A possible explanation is that a lower threshold is species‐specific (Ganaha‐Kikumura & Kijima, 2016). Moreover, thrips are not only affected by the temperature but also by the humidity, photoperiod and other environmental factors (Dos Santos et al, 2021; Ekesi et al, 1999; Hajar et al, 2011; Nakao, 1994), as well as host plants and plant secondary metabolites (Y. Gao et al, 2021; Imai et al, 2001). These results suggest that the developmental potential of T. flavus was slightly greater than that of other types of thrips at lower temperatures.…”

In Northeast China, thrips have long been considered a secondary pest of soybean until recent years. No study has provided clear reports regarding the effects of temperature on the development and reproduction of Thrips flavus Schrank (Thysanoptera: Thripidae). Our aim was to study whether the population dynamics of T. flavus were affected by temperatures. Thus, the development, reproduction and growth of T. flavus populations reared on soybean leaves were studied at five different constant temperatures. The temperature and rate of development from eggs to adults were linearly related between 19 and 31°C. The developmental threshold temperature and effective accumulated temperature were 11.60°C and 273.89 degree‐days for the whole generation. The viability of adult survival decreased with the increase in temperature between 19 and 31°C. The value of life expectancy of females ranged from 7.47 days (at 31°C) to 16.66 days (at 22°C), while the life expectancy value of males ranged from 5.33 days (at 19 and 31°C) to 17.0 days (at 25°C). The mean fecundity per female was highest at 19°C, with 7.85 eggs/day. The intrinsic rate of increase was the highest (0.102) at 31°C. The results obtained indicate that temperature is a key factor associated with the development and reproduction of T. flavus on soybean.
