AbstractRelationships between temperature and development rates of eggs, overwintered second-instar larvae, and all larval stages of Choristoneura fumiferana (Clem.) fed on artificial diet were determined. Egg development was observed at eight constant temperatures between 7 and 32°C. It was fastest at 30°C, and showed relatively little variability. The rate of emergence of overwintered second-instar larvae was observed at 10 constant temperatures between 4 and 33°C. Maximum development rates occurred at 30°C. Variability in emergence rates was large, but unimodal. Development rates of the second to sixth larval instars were measured at 10 constant temperatures between 7 and 36°C, and maximum rates were observed, again, at 30°C. Variability in the development rates of the larvae was large, with no correlations between the development rates of the various larval instars. The results of computer simulations of the insect’s seasonal history are presented and discussed.

The development rates of the immature stages of Carcinops pumilio (Erichson), a predator on eggs and first instar larvae of the house fly, Musca domestica L. were determined at six constant temperatures: 17.5, 19.5, 25.5, 30.0, 32.5 and 35.0°C. At the six temperatures, respectively, the median development times (days) were for eggs: 25.5, 14.3, 7.4, 3.8, 3.5 and 3.5; for larvae 37.7, 20.9, 9.4, 6.0, 6.0 and 6.0; and for pupae 42.8, 33.6, 17.0, 9.7, 7.4 and 8.3. Maximum development rates for all stages were at 32.5°C. The percentage of survival at the six temperatures, respectively, for larvae were 66, 92, 98, 100, 93 and 93, and for pupae were 56, 86, 90, 100, 93 and 78. The parameters for the Sharpe and DeMichele (1977) temperature-dependent development model and the Stinner et al. (1975) distribution of development model were estimated from the constant temperature data and validated under a variable temperature cycle.

AbstractIn this paper a process-oriented model of spruce budworm phenology is developed which produces simulations comparing favorably with observed phenological trends taken from literature. Major features of this model include: (1) non-linear descriptions of temperature-dependent development of larval instars and pupal stadium; (2) three sources of variability in development rates (intrinsic, sex-related, and microclimatic); and (3) generation of daily temperature cycles for four microhabitats from input min-max air temperature data.

Development Rates

Temperature has a significant influence on development rates of insects and mites. Many parametric models were built to describe the temperature-dependent development rates. However, these models provided different shapes of the curves of development rate versus temperature. For different datasets, investigators have to spend much time on considering which the parametric model is the best for describing the temperature-dependent development rates. In the present study, we encourage investigators to use an important non-parametric model, the loess method, which belongs to local regression methods. The loesS method is used to fit some published data on the development rate of aphids to check the goodness-of-fit. We find that the loess method is very flexible for fitting the given datasets. Thus, we consider that the loess method can be used to describe the effect of temperature on the development rate of insects or mites.

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.

Seasonal History

Many of the early papers on the spruce budworm, Choristoneura fumiferana (Clem.), included accounts of the general habits and seasonal history of the insect (9, 13, 18, 10, 22). Later papers have heen concerned principally with ecological or pathological relations, current infestations and damage, or chemical control. There has not been, however, any detailed account of the salient features of the development of the spruce budworm.
