ABSTRACT Agricultural grasslands are vital habitats for insects that provide key ecosystem services. However, conventional rotary mowers are proposed to cause significant insect mortality due to the high rotational speed of their blades and the resulting airflow.

Representation of acoustic communication signals by insect auditory receptor neurons [PDF]
Despite their simple auditory systems, some insect species recognize certain temporal aspects of acoustic stimuli with an acuity equal to that of vertebrates; however, the underlying neural mechanisms and coding schemes are only partially understood.

CONTRACTION IN GLYCERINATED MYOFIBRILS OF AN INSECT (ORTHOPTERA, ACRIDIDAE) [PDF]
The A substance of glycerol-treated myofibrils of the femoral muscles of the locust Gastrimargus musicus (Fabr.), removed by a salt solution of high ionic strength, has the properties of actomyosin. A phase contrast study of these fibrils, contracted by the addition of ATP, has revealed that the A bands of most myofibrils shorten during contraction ...

ABSTRACT The latitudinal diversity gradient (LDG), that is, the increase in species richness from the poles to the equator, is one of the oldest known ecological patterns. Its inverse (iLDG), where species richness increases toward higher latitudes, is less common but has recently attracted growing scientific interest.

FOOD CONSUMPTION AND UTILISATION OF THE GRASSHOPPER CHROTOGONUS LUGUBRIS BLANCHARD (ORTHOPTERA, ACRIDOIDEA, PYRGOMORPHIDAE) AND ITS EFFECT ON THE EGG DEPOSITION [PDF]
The grasshopper is found all the year round. It is considered as a pest for seedlings. The consumption index differed significantly between groups fed on different diets. Mated females consume more food than virgin females or virgin males.

Respiratory metabolism of developing eggs of Schistocerca gregaria has been individually monitored by means of scanning microrespirography. The freshly oviposited eggs consumed 7 nl of O2 /min./egg (50 µl O2/g/h) while the pharate 1st instar larvae ...

This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

The ability of biocontrol agents to overcome the immune defense of pests is a crucial issue. This is the first study of lysozyme activity as an inducible humoral component of the defense of Schistocerca gregaria, which depends on the recognition of the ...
