“…Similar to fecundity, intrinsic rate of increase (r m ) under constant temperatures (Li, 1990;Asin and Pons, 2001) also fitted a secondorder polynomial model (Fig. 6A, solid line; r m =−1.1884+0.1399T− 0.0033T 2 , R 2 =0.908).…”

“…As T max increased from 32°C to 40°C, the mean temperatures (24-26°C) used are still below or near the critical maximum mean temperatures (26-26.5°C) (Li, 1990;Asin and Pons, 2001), but aphid performance was dampened. Compared with observations from constant-temperature studies (see Ma et al, 2015), the observed (Dean, 1974;Lykouressis, 1985;Acreman and Dixon, 1989;Li, 1990;Asin and Pons, 2001;Yin et al, 2003) (adapted from Zhao et al, 2014 (Dean, 1974;Lykouressis, 1985;Li, 1990;Liu and Li, 1990;Sengonca et al, 1994;Yin et al, 2003 demographic parameters and fitness (r m ) of S. avenae were decreased to some extent when T max varied between 32°C and 36°C. When T max exceeded 36°C, the demographic parameters and fitness declined dramatically (Figs 2-6).…”

Daily temperature extremes play an important role in predicting thermal effects

Organisms in natural environments experience diel temperature fluctuations, including sporadic extreme conditions, rather than constant temperatures. Studies based mainly on model organisms have tended to focus on responses to average temperatures or shortterm heat stress, which overlooks the potential impact of daily fluctuations, including stressful daytime periods and milder nighttime periods. Here, we focus on daily maximum temperatures, while holding night-time temperatures constant, to specifically investigate the effects of high temperature on demographic parameters and fitness in the English grain aphid Sitobion avenae. We then compared the observed effects of different daily maximum temperatures with predictions from constant temperature-performance expectations. Moderate daily maximum temperatures depressed aphid performance while extreme conditions had dramatic effects, even when mean temperatures were below the critical maximum. Predictions based on daily average temperature underestimated negative effects of temperature on performance by ignoring daily maximum temperature, while predictions based on daytime maximum temperatures overestimated detrimental impacts by ignoring recovery under mild night-time temperatures. Our findings suggest that daily maximum temperature will play an important role in regulating natural population dynamics and should be considered in predictions. These findings have implications for natural population dynamics, particularly when considering the expected increase in extreme temperature events under climate change.

“…Extreme temperatures have been demonstrated repeatedly to depress aphid performance (e.g. Asin & Pons, 2001;Morgan et al, 2001), and high summer temperatures have been linked to the timing of the mid-season crash for both Macrosiphum euphorbiae (Barlow, 1962) and Diuraphis noxia (Basky, 1993). However, other studies have revealed no apparent relationship between temperature, or any other weather variable, and the timing of the population crash (e.g.…”

Abstract. 1. Aphid populations on agricultural crops in temperature regions collapse over a few days from peak numbers to local extinction soon after midsummer (e.g. mid-July in the U.K.). The populations recover 6-8 weeks later. There is anecdotal or incidental evidence of an equivalent mid-season population crash of aphids on grasses and forbs in natural vegetation.2. The ecological factors causing the mid-season population crash of aphids include a decline in plant nutritional quality and increased natural enemy pressure as the season progresses. Extreme weather events, e.g. severe rainstorms, can precipitate the crash but weather conditions are not a consistent contributory factor.3. The population processes underlying the crash comprise enhanced emigration, especially by alate (winged) aphids, depressed performance resulting in reduced birth rates, and elevated mortality caused by natural enemies.4. Mathematical models, previously applied to aphid populations on agricultural crops, have great potential for studies of aphid dynamics in natural vegetation. In particular, they can help identify the contribution of various ecological factors to the timing of the population crash and offer explanations for how slow changes in population processes can result in a rapid collapse of aphid populations.

“…Meteorological factors, especially temperature, are the main environmental variables acting on aphids, associated to the occurrence of population peaks (Dixon, 1998;Tang et al, 1999;Asin & Pons, 2001). Several authors (Chattopadhyay et al, 2005;Zamani et al, 2006;Klueken et al, 2009) have predicted aphid occurrence by meteorological factors.…”

-The objective of this work was to predict the occurrence of alates of Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae (Hemiptera, Aphididae) in Brassicaceae. The alate aphids were collected in yellow water traps from July 1997 to August 2005. Aphid population peaks were predicted using a degree-day model. The meteorological factors, temperature, air relative humidity, rainfall, and sunshine hours, were used to provide precision indexes to evaluate the best predictor for the date of the first capture of alate aphids by the traps. The degree-day model indicated that the peak population of the evaluated aphid species can be predicted using one of the following biofix dates: January 1 st , June 1 st , and the date of the first capture of the alate aphid species by the yellow water traps. The best predictor of B. brassicae occurrence is the number of days with minimum temperature >15°C, and of L. erysimi and M. persicae, the number of days with rainfall occurrence.Index terms: Brassica oleracea, pest management, population dynamics, thermal requirements. Previsão da ocorrência de pulgões alados em BrassicaceaeResumo -O objetivo deste trabalho foi prever a ocorrência de formas aladas de Brevicoryne brassicae, Lipaphis erysimi e Myzus persicae (Hemiptera, Aphididae) em Brassicaceae. Os pulgões foram coletados com armadilhas tipo bandeja amarela com água, no período de julho de 1997 a agosto de 2005. Os picos populacionais dos pulgões foram previstos com uso de modelo de graus-dias. Os fatores meteorológicos temperatura, umidade relativa do ar, precipitação pluvial e insolação foram utilizados para a obtenção de índices de precisão para determinar o melhor previsor da data da primeira captura de pulgões alados pelas armadilhas. O modelo de graus-dias indicou que o pico populacional dessas espécies de pulgões pode ser previsto ao se utilizar uma das seguintes datas biofix: primeiro de janeiro, primeiro de junho e data da primeira captura de alados das espécies de pulgão por armadilha tipo bandeja amarela com água. O melhor previsor da ocorrência de B. brassicae é o número de dias com temperatura mínima >15°C, e de L. erysimi e M. persicae, o número de dias com ocorrência de chuvas.Termos para indexação: Brassica oleracea, manejo de pragas, dinâmica populacional, exigências térmicas.
