The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Entomophaga grylli is a fungal pathogen which infects and kills grasshoppers.It is the causal agent of one of the most widespread diseases affecting grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores.

Biological control agents of weeds include seed predators, herbivores, and plant pathogens. Biological control can have side-effects on biodiversity through attacks on non-target species by any of the above mechanisms, especially when a species is introduced without a thorough understanding of the possible consequences.
Biological control is being investigated, and spores of the protozoan parasite Nosema locustae can be used mixed with bait to control grasshoppers, being more effective with immature insects. [84] On a small scale, neem products can be effective as a feeding deterrent and as a disruptor of nymphal development.

LUBILOSA was the name of a research programme that aimed at developing a biological alternative to the chemical control of locusts.This name is an acronym of the French title of the programme: Lutte Biologique contre les Locustes et les Sauteriaux (biological control of locusts and grasshoppers).
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
While the understanding and incorporation of tritrophic interactions in pest control offers a promising control option, the sustainable biological control of pests requires a dynamic approach that involves diversity in all of the species present, richness in natural enemies, and limited adverse activity (i.e., minimal pesticide use).
