“…Beside exposure to short periods of heating, temperature variation in comparison with constant temperatures can also help explain the more rapid development of insects at the same mean daily temperatures [17]. Blanckenhorn [11] has described, using the yellow dung fly, how development time is shorter at variable temperatures in the field than with the same mean constant temperature.…”

“…Likewise, growth is expected to be related to both duration and quantum of temperature above thresholds. Insects have frequently been shown to develop more rapidly, lay more eggs, suffer a lower mortality, or complete their life cycle within a wider temperature range when temperatures are fluctuating, like they predominate in the field, than at constant temperatures, as long as the maximum and minimum of the fluctuating temperature are within the optimal range of development for the organism [15][16][17]. While the effects of fluctuating versus constant temperatures have already been well studied, little is currently known about the effects of short periods of heating for larval development and for the growth of Palaearctic insect species in the field.…”

Temperature has been shown to play an important role in the life cycles of insects. Early season feeders in Palaearctic regions profit by the high nutritional quality of their host plants early in the year, but face the problem of having to develop at low average springtime temperatures. This study examines the influence of short periods of heating in the field on larval development and on mortality with the model system Galeruca tanaceti L. (Coleoptera: Chrysomelidae), an early season feeder, that hatches at low springtime temperatures. Field and laboratory experiments under different constant and variable temperature regimes were performed. While in the field, the average daily temperature was close to the lower developmental threshold of the species of 10.9• C; maximum temperatures of above 30 • C were sometimes reached. Larvae developed significantly faster, and pupae were heavier, in the field and in an assay with short periods of heating than at the same average temperature under constant conditions in the laboratory. We conclude that larvae profit substantially from short periods of heating and temperature variation in the field and that intervals of high temperature enable insect survival and exploitation of nutrient-rich food resources at early times in the season.

“…comm.). These parameters suggest more rapid development in NZ populations where usually too wet for L. jacobaeae (above 1,670 mm) than in Australia (Allsopp et al 1991) and Japan (Jallow and Matsumura 2001) but slower than those in Greece (Mironidis and Savopoulou-Soultani 2008). Since the threshold temperature for development of the parasitoids is similar to that for the pest (data from Tillman and Powell 1991;Tillman et al 1993), the generation time ratios (GTR) are constant with temperature.…”

Potential effects of climate change on biological control systems: case studies from New Zealand

et al. 2012

Biological control systems are integral to New Zealand's success as a nation reliant on exporting quality agricultural, forestry and horticultural products. The likely impacts of climate change projections to 2090 on one weed and four invertebrate management systems in differing production sectors were investigated, and it was concluded that most natural enemies will track the changing distributions of their hosts. The key climate change challenges identified were: disparities in natural enemy capability to change distribution, lack of frosts leading to emergence of new pests and additional pest generations, non-target impacts from range and temperature changes, increased disruptions caused by extreme weather events, disruption of host-natural enemy synchrony, and insufficient genetic diversity to allow evolutionary adaptation. Five classical biological control systems based on the introduced species Longitarsus jacobaeae, Cotesia kazak, Aphelinus mali, Microctonus aethiopoides and Microctonus hyperodae are discussed in more detail.

“…According to the present study, the optimal temperature for mass rearing based on those tested is around 25°C. Other studies have shown that the developmental rate remained the same with constant and alternating temperature (Liu et al, 1995;Mironidis and Savopoulou-Soultani, 2008). Therefore, the climate of Congjiang is highly suited to the factory-based mass rearing of L. haraldusalis.…”
