Outbreaks of grasshoppers (Orthoptera: Acrididae) often cause serious ecological damage. Recently, there has been interest in using natural enemies of grasshopper for their biological control. This study examined the biology and predation on grasshoppers by Eremias argus, a common lizard in Inner Mongolia. Its developmental duration and life history are consistent with adaptation to grasshopper phenology. The diet structure of E. argus included grasshoppers, beetles, ants, leafhoppers, moths, bees and spiders. A positive correlation between E. argus population numbers and grasshopper population numbers was highly significant. We built models describing the functional response and intraspecific competition for E. argus adults. The functional feeding response of E. argus on grasshopper was classed as Holling type III. The maximum number of grasshoppers consumed by female and male adults were 11.2 and 7.0 individuals per day, respectively. Predatory ability was strongest in female adults, with the second and third instars of Oedaleus asiaticus preferred. The predation ratios(E) of E. argus on grasshoppers declinedwith increasing lizard density, especially for female adult E. argus. E. argus could play an important role in grasshopper control and maintaining a population of E. argus in the grassland ecosystemcould effectively control low-density grasshopper populations on grassland. Suggestions on how E. argus could fit into an IPM programme for biological control of grasshopper are discussed.

Calliptamus italicus is a migratory species of grasshopper that can cause serious damage to grasslands in Xinjiang, China. In this study,we examined the effects of different temperatures (23, 26, 29, 32, and 35 °C) on the lifecycle and life table parameters. The results showed that temperature strongly influences the growth and development of C. italicus. At temperatures ranging from 23 to 35 °C, the development time was negatively linearly related to temperature (P b 0.01). The time of development from an egg to an adult (pre-oviposition) ranged from86.8 d at 26 °C to 40.6 d at 35 °C, and no oviposition occurred at 23 °C. An average of 687.1 degree-days was required for complete development to occur above the lower threshold temperature (18.3 °C). Egg hatching rates and nymph and pre-adult survival rates were lowest at 23 °C (95.6%, 72.6%, and 0%, respectively) and highest at 32 °C (97.8%, 86.2%, and 88.7%, respectively). The mean total fecundity ranged from 41 eggs/female at 26 °C to 55 eggs/female at 32 °C. The sex ratio (% females) ranged from30 to 52%. The intrinsic rate of population increase (rm) at the different temperatures ranged from 0.0020 to 0.0447 d−1, with the highest value recorded at 32 °C. These results indicate that temperature significantly affects the biology of C. italicus and that the optimal temperature range for its development is 26–32 °C.

The broad insecticide chlorantraniliprole causes death by activating the ryanodine receptor, and its effects on detoxification enzymes limit its proper rotation and mixed use with other pesticides. Therefore, we studied the changes in detoxification enzymes activities of Locusta migratoria L. nymphs induced by chlorantraniliprole. When nymphs of locust were treated with chlorantraniliprole only on the first day, the LC50 was 4.8 μg mL−1, and the activities of esterases (ESTs) and glutathione S-transferases (GSTs) increased, but the activity of multifunction oxidases (MFOs) increased only at 3 day after treatment, although the activities fluctuated over 7 days after treatment. When the nymphs of locust were treated for 7 days, the LC50 was 2.3–3.1 μg mL−1, and similarly the activities of ESTs and GSTs increased while that of MFOs decreased significantly in a concentrationdependent manner. Synergism of triphenylphosphate, piperonyl butoxide, and diethyl maleate with chlorantraniliprole toxicity confirmed the correlation between chlorantraniliprole and changes in ESTs, GSTs, and MFOs activities. Herein, we improved the knowledge about the effects of chlorantraniliprole on these detoxification enzymes of L. migratória. These results clarified the effects of chlorantraniliprole on the activities of ESTs, GSTs, and MFOs in L. migratoria, and will provide insight into its proper rotation and mixed use with other pesticides.
