ABSTRACTTemperature-dependent development influences production rates of arthropods, including crustaceans important to fisheries and agricultural pests. Numerous candidate equation types (development functions) exist to describe the effect of temperature on development time, yet most studies use only a single type of equation and there is no consensus as to which, if any model predicts development rates better than the others, nor what the consequences of selecting a potentially incorrect model equation are on predicted development times. In this study, a literature search was performed of studies fitting development functions to development of arthropod larvae (99 species). The published data of most (79) of these species were then fit with 33 commonly-used development functions. Overall performance of each function type and consequences of using a function other than the best one to model data were assessed. Performance was also related to taxonomy and the range of temperatures examined. The majority (91.1 %) of studies were found to not use the best function out of those tested. Using the incorrect model lead to significantly less accurate (e.g., mean difference ± SE 85.9 ± 27.4 %, range: −1.7 to 1725.5 %) predictions of development times than the best function. Overall, more complex functions performed poorly relative to simpler ones. However, performance of some complex functions improved when wide temperature ranges were tested, which tended to be confined to studies of insects or arachnids compared with those of crustaceans. Results indicate the biological significance of choosing the best-fitting model to describe temperature-dependent development time data.HighlightsTemperature-dependent development functions of arthropod larvae were reviewed79 published datasets were re-tested and fit with 33 different function types91.1 % of published studies did not fit their data with the best function of those testedPerformance differed among functions and was related to taxon and temperature range testedFunction type impacted predicted development times, so using the best function matters

The duration of embryonic development and that of well-fed older stages were determined for Pseudocalanus acuspes, P. minutus, P. moultoni, and P. newmani. Excluding abnormal individuals, the times for older stages were lognormally distributed, with similar variances among species, stages, and temperatures. Some residual variance occurred among families reared together. Copepod rearings should take these sources of variance into account. Development times (D) were described well by Bělehrádek's temperature (T) function, D = a(T − α)−b, with b = 2.05 for all species from previous studies, and α and a fitted for embryonic development. Only a needed to be fitted for older stages (i.e., "equiproportional" development). Relative times to given stages at all temperatures (i.e., relative values of a) were similar in three species, but P. minutus deviated from this pattern. Values of α were directly related to presumed environmental temperatures in the species' ranges. Values of a were directly related to egg and body sizes of the different species. The temperature functions can be used to predict the lengths of the generations in these four species in nature when food is adequate.

AbstractTemperature-dependent development of eggs, larvae, and pupae of the speckled green fruitworm, Orthosia hibisci Guenée, at constant temperatures of 5–30.0 °C, 7.5–27.5 °C, and 0.8–20.8 °C, respectively, was described. Development times decreased with increasing temperatures and minimum developmental times in eggs, larvae, and pupae occurred at ca. 27.5, 25, and 20.8 °C, respectively. Variation in development times of all life stages was modelled accurately (R2 values 0.98–0.99) with a Weibull distribution. Relationships between temperature and developmental rates of all life stages were described by linear degree-day (DD) and nonlinear poikilotherm models. There were significant differences (ANOVA, P < 0.05) among the slopes of regression equations describing developmental rates of different life stages and larval instars. Minimum developmental temperatures for eggs (3.4 °C), first- through fifth-instar larvae (4.7, 2.9, 3.6, 3.5, and 3.7 °C), and pupae (2.8 °C) were determined by extrapolation of linear regression equations to the x-intercept. Median development time of eggs, first- through fifth-instar larvae, and pupae required 99.0, 44.2, 51.5, 52.4, 57.1, 69.9, and 61.3 DD above the minimum developmental temperatures, respectively. Developmental rates of eggs and all larval instars averaged were described by six-parameter models exhibiting low- and high-temperature inhibition. Development of pupae was best described by a four-parameter model exhibiting low- but no high-temperature inhibition. This information should be useful for developing a phenology model to improve management actions against O. hibisci.

Parameters for a degree-day model (DD) and the Sharpe-DeMichele poikilothermic model (POIK) were estimated for the development of Rhyacionia frustrana (Comstock) immature stages. A comparison of the accuracy between the two models was made for eggs, larvae, and pupae. The DD and POIK model were equally effective for predicting development of eggs, but the POIK model was superior for predicting larval and pupal development. Regression analysis of predicted vs. observed development days show a good fit (R2 &gt; 0.99) for eggs using both models, a relative good fit (R2 &gt; 0.90) for larvae and a poor fit (R2 &lt; 0.85) for pupae. Threshold temperatures were at 10.0°C for eggs, 7.0°C for larvae, and 9.8°C for pupae. Optimum hatch was 100% for eggs at 24°C and required 81 DD; optimum survival was 77% for larvae at 21°C and required 704 DD; and optimum eclosion from pupae was 55% at 26°C and required 227 DD.
