More than 20 years ago, an oxytocin/vasopressin-like peptide, CLITNCPRGamide, was isolated from the locust, Locusta migratoria [Proux JP, et al. (1987) Identification of an arginine vasopressin-like diuretic hormone from Locusta migratoria. Biochem Biophys Res Commun 149:180-186]. However, no similar peptide could be identified in other insects, nor could its prohormone be cloned, or its physio...

Efficacy of five water based insecticides on Schistocerca gregaria (Forskal), Locusta migratoria (Linnaeus),and multiple grasshoppers species applied as low volume (LV) and Ultralow (ULV) were tested. Obtained data indicated that descending order efficacy follow: chlorpyrifos, thiamethoxam + chlorantraniliprole, spinetoram methoxyfenozide, chlorantraniliprole then pyridalyl, in case S. both met...

It is becoming increasingly clear that global warming is taking place; however, its long-term effects on biological populations are largely unknown due to lack of long-term data. Here, we reconstructed a 1,910-y-long time series of outbreaks of Oriental migratory locusts (Locusta migratoria manilensis) in China, on the basis of information extracted from >8,000 historical documents. First by an...

The interaction between temperature and diet quality can affect the life history of ectotherms. The rate and ratio at which protein and carbohydrate are obtained from food are important aspects of diet quality, and insects have a well-developed capacity to adjust their feeding behaviour and post-ingestive physiology to regulate intake and allocation of these nutrients. If the supply of protein ...
