“…Nevertheless, the average immature development time (from the first nymphal stage up to the post-reproductive adult) was 25.7 days for A. gossypi and 24.8 days for M. persicae. These values were similar in our study, since temperature [33] and host plant conditions [34] affect the length of the development of aphids. Both species showed four nymphal stages, as found by Dixon et al [27], lasting between 1.1-1.5 days, on average.…”

Viral diseases, transmitted by aphids, are the most limiting problems in chili pepper crops. Understanding the demographic features of these aphids, may thus assist the design of better disease control strategies in chili peppers. Aphid species found in chili pepper crops in south western Colombia were identiﬁed as Aphis gossypii Glover and Myzus persicae (Sulzer). An array of life-history parameters of both aphid species were investigated at (25 ± 0.5) ◦C, (75 ± 1.75) % r.h., L12:D12, and LS 5-Light Storm in chili pepper crops. Both aphid populations consisted only of parthenogenetic females, showing a similar average development time—from the ﬁrst nymphal instar to the post-reproductive adult—, female longevity, and daily average fertility values. The length of the reproductive period was higher for M. persicae. A. gossypii reached its adult state signiﬁcantly faster than M. persicae. The intrinsic rate of population growth (rm) was lower for M.persicae (0.39) compared to A. gossypii (0.43). Results showed a potential for fast population growth in both species, which would enhance their role as virus vectors. The information acquired is essential to develop pest management initiatives for these two aphid species.

“…Temperature, as an important ecological factor, has a significant impact on the development duration, fecundity and population dynamics of insects (Campbell et al ., 1974; Özder and Ozgur, 2013; Cao et al ., 2018). A large number studies have shown that the developmental duration of insects shortens with the increase of temperature over the appropriate temperature range (Cui et al ., 2018; Abu Alloush, 2019).…”

“…The best indicator to measure the relationship between insect population growth and the temperature is intrinsic growth rate, which can generally reflect the effects of temperature on insect development, reproduction and survival. Typically, the intrinsic growth rate of aphid population is the highest in the temperature range of 25–30°C (Gilbert and Raworth, 1996; Özder and Ozgur, 2013), such as Schizolachnus pineti in 24–36°C (Holopainen and Kainulainen, 2004) and Cinara pinea in 21°C (Shao et al ., 2017). In this study, the intrinsic growth rate of C. cedri is the highest at the temperature of 20°C.…”

Temperature is one of the main factors affecting insect growth, development and reproduction. The effects of temperatures (10, 15, 20, 25 and 30°C) on the development and reproduction of Cinara cedri Mimeur (Hemiptera: Aphidoidea: Lachnidae) fed on Cedrus deodara (Roxb.) G. Don were evaluated in this study. With the increase of temperature from 10 to 30°C, the development duration at different development stages gradually shortened. There was a significant positive correlation between the developmental rates and temperature, following a quadratic regression model. The lower developmental threshold temperature (C) and effective accumulated temperatures (K) for completing a generation were 4.13°C and 263.4 degree-days, respectively. The highest fecundity was observed at 20°C with 25.74 first-instar nymphs/female. Both the highest intrinsic rate of increase (r, 0.11 ± 0.03) and net reproduction rate (R0, 19.06 ± 2.05) were observed at 20°C, whereas the lowest values of r (0.05 ± 0.01) at 10°C and R0 (5.78 ± 0.88) at 30°C were observed. The results suggest that temperature significantly affects the biology of C. cedri and the optimal temperature for its development is 20°C.

“…The oleander aphid Aphis nerii is an important invertebrate herbivore of milkweed that shows strong seasonal trends in population dynamics (Smith et al 2008). Aphids are phloem feeders and reproduce asexually through viviparous parthenogenesis (Powell et al 2006), with nymphs reaching sexual maturity in 7–10 days (Özderl and Saǧlam 2013). Aphids migrate north each spring, arriving on plants in our study area (southern Ontario) approximately 9–10 weeks after milkweed germination.…”

Timing of short‐term drought structures plant–herbivore dynamics

Drought is an important stressor that affects plant growth, survival and physiology and, through plant responses, alters plant–herbivore interactions and herbivore population dynamics. Short‐term drought can occur at different times during a growing season, affecting herbivore populations and plants at various stages of development and growth. As phenology influences drought response, drought timing could strongly structure plant–herbivore interactions. We grew common milkweed plants with or without its dominant aphid herbivore, allowing both plants and herbivore populations to develop over time as in a typical growing season. To determine how drought timing affects plants and aphid populations, we applied short‐term (1 week) drought at different times. Plants and aphids were sensitive to drought timing, with a few weeks difference shifting the effects of drought from minimal to causing massive declines in plant growth, plant survival and herbivore population density. Aphid herbivory added to or overrode drought consequences in plants, with different plant fitness components responding distinctly to herbivory. Drought timing also affected whether plant and herbivore responses were parallel or divergent, suggesting that shifts in the seasonal timing of drought have the potential to disrupt plant–herbivore interactions and affect the larger ecological community. Our results show drought timing has important and disparate consequences for herbivores and their host plants and indicates the necessity of considering phenology and timing in assessing drought response.
