TLDR
In this article, a temperature-dependent model for predicting green peach aphid population development in potato fields was devised and tested and a laboratory estimate of generation time was utilized to derive expected generation number from field accumulated degree days (1975-77).Abstract:
A temperature-dependent model for predicting green peach aphid population development in potato fields was devised and tested. A laboratory estimate of generation time was utilized to derive expected generation number from field accumulated degree days (1975–77). Different aphid populations were produced in replicated field plots (1975–77) with various application rates of the systemic insecticide, aldicarb. Density data from these plots were regressed on the expected number of generations to derive prediction equations. These equations were coupled in a Fortran computer program with a degree day algorithm. Weather forecasts, therefore, provide input for future aphid population predictions. The model is being used to evaluate various control strategies and to decide on spray dates from weather forecasts.read more

Aphid-transmitted potato viruses: The importance of understanding vector biology
TL;DR: This review addresses some of the biological complexities presented by aphid-transmitted viruses of potato, Solanum tuberosum L., and their vectors and discusses the application of this knowledge to the management of potato viruses with particular emphasis on seed potato production.

Effects of High and Fluctuating Temperatures on Myzus persicae (Hemiptera: Aphididae)
TL;DR: It seems that, in midwestern North America, green peach aphid would benefit from an increase in mean summer temperature of 2.5–3.5°C, and had greater fecundity under fluctuating conditions.

How temperature affects development and reproduction in spiders : a review
Daiqin Li,Robert R. Jackson +1 more
TL;DR: It is argued that the thermal adaptations of spiders might have important roles in fine-tuning the species' life-history strategies: much of this variability is probably a consequence of adaptations to the different thermal conditions prevailing in the natural habitats of these species.

Effects of simulated heat waves on an experimental community of pepper plants, green peach aphids and two parasitoid species
TL;DR: The results demonstrate that heat waves could have important effects on community structure, and on important, community-level processes such as intra-guild interactions and trophic cascades.

Modelling development time of Myzus persicae (Hemiptera: Aphididae) at constant and natural temperatures
Shu-sheng Liu,Xue-duo Meng +1 more
TL;DR: Comparison of the observed with simulated distributions of adult emergence indicates that all three models can simulate the development of M. persicae very well when the temperature does not go below 4°C, the notional low temperature threshold of the day–degree model.

A Modified Sine Wave Method for Calculating Degree Days
TL;DR: A FORTRAN program is described which uses maximum and minimum temperatures to compute heating and cooling degree days (between and below thresholds, respectively), and a method of correcting for local bias using linear regression is described.
