“…Our results showed that the egg stages of A. hygrophila (excluding cold treatment periods) were significantly shorter after exposure to temperatures at 4-12°C for 4 or 7 days, compared with those at constant 25°C. As Liu and Meng (1999) pointed out that development thresholds, produced by the linear regression technique or by nonlinear models, do not model the processes that control development at low temperatures. They are simply notional estimates of thresholds derived by extrapolation from development rates at moderate and high temperatures, and thus are not points with any intrinsic relationship to a true development threshold.…”

The flea beetle, Agasicles hygrophila, was introduced to control the alligator weed, Alternanthera philoxeroides, in southern China and redistributed for over 20 years. The beetle has succeeded in establishing local field populations. Temperature, especially extreme low temperature in winter, is hypothesized to be a key factor determining the distribution of A. hygrophila. We studied the adult reproduction and leaf consumption, egg hatching rate, larval and pupal survival and development of A. hygrophila in response to low non-freezing temperatures. Female and male adults of A. hygrophila survived at 4°C for 11.4 and 14.2 days, respectively, and adult longevity increased with increasing temperature from 4 to 12°C. Adult longevity was significantly longer at 12°C than at 25°C, and the fecundity at 12°C was approximately 10% of that at 25°C. When A. hygrophila eggs, first instar larvae and pupae were kept at 4-12°C for 1, 4, 7 or 10 days, respectively, and then transferred to 25°C, over one third of eggs hatched after cold treatment at 4°C for 7 days, with an average egg development duration of 3.6 days excluding the cold treatment period. Egg hatching rate increased as temperature during the cold treatment increased and the cold treatment duration reduced. Eggs pretreated at 12°C and those kept constantly at 25°C did not differ in their hatching rates. The first instar larvae of A. hygrophila could not survive 12°C or lower, and exposure to these low temperatures resulted in 100% mortality and a lifespan shorter than 1 day. Eclosion rate of A. hygrophila pupae was 71, 60, 24 and 15% after cold treatment at 4-12°C for 1, 4, 7 and 10 days, respectively, which was lower than that at constant 25°C (over 93%) but did not differ among the cold treatments. Comparing with the prediction in 1980s that A. hygrophila could not overwinter further north than the approximate position of the 9°C isotherm, our recent survey showed that A. hygrophila

The linear model can also be used to estimate the lower developmental threshold by T 0 = -a/b°C, for comparison purposes with the non-linear model.…”

The beneficial mite Typhlodromus pyri is a key predator of grapevine rust mite Calepitrimerus vitis in Pacific coastal vineyards. Rust mite feeding has been associated with damage such as stunted, deformed shoot growth and reductions in fruit yield. The life history traits of T. pyri were assessed at seven constant temperatures (12.5, 15, 17.5, 20, 25, 30 and 35 °C) to determine population parameters providing data to better predict biological control of C. vitis populations by T. pyri in vineyards. Successful development from the egg to adult stage was observed at temperatures ranging from 15 to 30 °C. Constant exposure to 12.5 and 35 °C resulted in 100 % mortality in immature T. pyri. Developmental times, fecundity and longevity were highest at 25 °C. The estimated minimum and maximum developmental thresholds were 7.24 and 42.56 °C, respectively. Intrinsic rate of increase (r ( m )) was positive from 15 to 30 °C indicating population growth within this range of temperatures. Net reproductive rate and intrinsic rate of increase were greatest at 25 °C. These developmental parameters can be used to estimate population growth, determine seasonal phenology and aid in conservation management of T. pyri. Results presented in this study will aid in evaluating the effectiveness of T. pyri as a key biological control agent of C. vitis during different periods of the growing season in Pacific Northwest vineyards.

Abstract. Dubas bug, Ommatissus lybicus Bergevin, is an important pest of date palm on the Arab peninsula. This sucking insect causes great damage to the trees and reduces the quantity and quality of the dates. Effect of temperature on the development of the immature stages of O. lybicus was studied in the laboratory by rearing them at nine constant temperatures, ranging from 15 to 35°C. Development was successfully completed at temperatures ranging from 20 to 35°C for eggs and from 20 to 32.5°C for nymphs. The lower thermal thresholds for development of eggs, nymphs and egg-adult were estimated by means of linear regression as 12.9, 12.9 and 13.2°C, respectively. Thermal units required for the development of the same stages were 572.5, 648.2 and 1184.4 degree-days, respectively. The lethal high temperatures were also estimated using a nonlinear model as 34.5, 43.4 and 34.6°C for eggs, nymphs and total immature stages, respectively. The development rate and survival data indicate that the optimum temperature range for O. lybicus is 25-27.5°C.
