The development, survivorship and reproduction of red palm weevil Rhynchophorus ferrugineus, reared on five ornamental palm slices, were studied in the laboratory at constant temperature of 26°C. The developmental time of R. ferrugineus was 68.8 days on Washington palm (Washingtonia filifera), 74.1 days on Canary Island date palm (Phoenix canariensis), 82.1(More)
High temperature often induces oxidative stress and antioxidant response in insects. This phenomenon has been well documented under controlled laboratory conditions, but whether it happens under fluctuating field conditions is largely unknown. In this study, we used an invasive lace bug (Corythucha ciliata) as a model species to compare the effects of(More)
The sycamore lace bug, Corythucha ciliata (Say) (Hemiptera: Tingidae), is an important invasive exotic pest of Platanus (Proteales: Platanaceae) trees in China. The objective of this study was to determine the effects of temperature on C. ciliata in the laboratory so that forecasting models based on heat accumulation units could be developed for the pest.(More)
Biological invasions are predicted to be more frequent as climate change is increasing its positive impact on the prevalence of invasive exotic species. Success of insect invaders in different temperature zones is closely related to their tolerance to temperature extremes. In this study, we used an exotic lace bug (Corythucha ciliata) as the study organism(More)
The sycamore lace bug, Corythucha ciliata is a new, invasive pest of Platanus trees in China. Although C. ciliata is often subjected to acute low temperatures in early winter and spring in northern and eastern China, the cold tolerance of C. ciliata has not been well studied. The objectives of this study were to determine whether adults of C. ciliata are(More)
Supercooling point (SCP) of female adults of Corythucha ciliata was significantly lower than that of male adults, with an average being -11.49 degrees C and -9.54 degrees C, respectively. Low temperature survival of adults of different ages indicated that there were differences in cold survival ability among age groups of adults. Nonlinear regression(More)
Although increases in mean temperature (MT) and extreme high temperature (EHT) can greatly affect population dynamics of insects under global warming, how concurrent changes in both MT and EHT affect invasive species is largely unknown. We used four thermal regimes to simulate the increases in summer temperature and compared their effects on the(More)
Plant invasions can alter the trophic interactions of invaded ecosystems because of phenological differences between native and invasive plants that may affect the population dynamics and diets of indigenous arthropod herbivores. This issue, however, has seldom been studied. We here report on how abundance and diet of a local tussock moth (Laelia coenosa)(More)
Corythucha ciliata (Say), an invasive pest originating from North America, causes severe damage on sycamore trees. However, little is known about the population genetics and evolutionary forces underlying the invasiveness of this important pest. In the present study, we use three mitochondrial genes (COI, ND1 and ND5) and nine microsatellite markers to(More)
Under high temperature conditions, insects can tolerate to survive through various physiological mechanisms, which have been well documented in laboratory studies. However, it is still unclear as to whether these laboratory data can scale up to those in the field. Here we studied dynamics of heat-induced metabolites in Corythucha ciliata adults under both(More)
