“…Furthermore, even though temperatures higher than 25°C inhibited adult emergence of both species, the adult emergence and pupation rates of B. impatiens were lower than those of B. cellarum. These results illustrate that the development of the 4th instar larvae and pupae of B. cellarum are more tolerant to the heat stress than those of B. impatiens, which confirms the reports of Wang, (2015);Zhu et al, (2018).The harmful effects of high temperatures on insects depend not only on temperature level but also on the exposure time. However, there was no previous research on the effect of exposure time on pupation rate and the pupal stage of the two Bradysia species.…”

“…The adult emergence rate of each species was suppressed as temperature and exposure time increased ( (Cheng et al, 2017;Du et al, 2007;Zhu et al, 2018). The developmental duration of Chilo suppressalis larvae was prolonged about 2 weeks by heat stress at 36°C for 4 hr compared with that at 24°C for 4 hr (Luo, Zhang, Jue, Guo, & Zhu, 2005).…”

Bradysia cellarum Frey and Bradysia impatiens Johansen are major pests of vegetable crops, as well as edible mushrooms and ornamental plants, and damage to hosts resulting in economic losses. Temperatures above the optimum levels for these pests have been predicted to regulate their population growth during summer. The aim of the present study was to examine the effects of both heat stress and exposure time on the growth and development of eggs, larvae and pupae for two Bradysia species. The egg stage, egg hatching rate, 4th instar larval stage, pupation rate, pupal stage and adult emergence rate were observed after exposing at high temperatures of 34°C, 37°C and 40°C for 1, 2, 4 and 6 hr. The results showed that 34°C, 37°C and 40°C for 1‐, 2‐, 4‐ and 6‐hr exposure treatments prolonged the developmental stage of egg, 4th instar larva and pupa, while decreasing the egg hatching rate, pupation rate and adult emergence rate. This suggests that increasing temperature or prolonging exposure time to the heat stress could significantly affect insect survival, growth and development. Our study could provide an ecological basis for pests’ management strategy by using short‐term heat stress.

“…Cydia pomonella (L.) adults were tolerant to exposure for 2 h to 41-43°C (Chidawanyika & Terblanche, 2011). Nevertheless, two root maggots, Bradysia odoriphaga Yang & Zhang and Bradysia difformis Frey, were both susceptible to 38°C heat shock, with all Ltime 50 <2.2 h in their eggs, second and fourth instars, pupae, and adults (Zhu et al, 2018). A 0.5-h exposure to 39°C caused approximately 50% mortality in Frankliniella occidentalis (Pergande) adults (Li et al, 2011a).…”

Climate change is expected to increase the frequency of periods of extreme weather events, including heat waves that are harmful to arthropod natural enemies. We studied the thermotolerance of the ladybeetle Serangium japonicum Chapin (Coleoptera: Coccinellidae), an important native predator of the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) in China. Serangium japonicum eggs, first‐ and fourth‐instar larvae, pupae, and adults were subjected to a range of high temperatures (36, 39, 42, 43.5, and 45 °C) at intervals between 15 and 720 min. Survival was compromised and declined sharply for all life stages at temperatures of 42 °C and higher. First instars were the least heat tolerant, and eggs were typically the most resistant. Egg predation by S. japonicum did not differ whether the adult beetles were subjected to either heat shock or starvation first. Heat shock treatments at 36 °C did not impede adult egg consumption, treatments at 39 °C crippled ladybeetle's egg consumption for 8 h following treatment but recovered predatory capacity within 24 h after treatment. However, treatments at 42 °C greatly impaired ladybeetle's predatory capacity. After experiencing heat shock at 39 and 42 °C, adults significantly increased the amount of time they spent resting, which is the probable cause of predation decline after heat exposure. These results demonstrate that short periods of extreme heat exposures have a detrimental impact on S. japonicum survival and predation, but the effect was dependent on duration and life stage. Overall, these findings can help predict population dynamics and success of biological control of whitefly by S. japonicum in a warming world.

Soil microorganisms can form a stable dynamic system with plant root systems. The composition of the soil microorganism community is related to the growth and stress resistance of plants; in turn, soil microorganisms are also regulated by plant genotypes and root exudates. Therefore, research on how to identify microorganisms that are beneficial or harmful to plants, study the interaction between microorganisms and plants, and form stable microbial communities for better plant growth plays an important role in sustainable agriculture. It is of great significance to identify and analyze rhizosphere microorganisms and plant endophytes through high-throughput methods, especially to analyze which microorganisms are beneficial to plants, which are harmful to plants, and which are opportunistic pathogens. This review provides a theoretical basis and outlook for the utilization of beneficial microbes in sustainable agriculture.
