Grasshoppers eat large quantities of foliage both as adults and during their development, and can be serious pests of arid land and prairies. Pasture, grain, forage, vegetable and other crops can be affected. Grasshoppers often bask in the sun, and thrive in warm sunny conditions, so drought stimulates an increase in grasshopper populations.
The life cycle of the Javanese grasshopper varies in different parts of its range, but in general, there is a single generation of insects each year. Up to four egg pods are laid in moist soil in forest clearings. When the eggs hatch, the nymphs pass through six or seven instar stages before becoming winged adults. Both nymphs and adults are ...
The desert environment of T. eques is often unpredictable and allows the grasshopper only about four months, the time between the onset of the summer rains and the arrival of the winter freeze, to complete its entire life cycle. Growth and development are further slowed by cold desert nights, and in October, cold days.
Orthoptera (from Ancient Greek ὀρθός (orthós) 'straight' and πτερά (pterá) 'wings') is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā.
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.

The green-striped grasshopper is single-brooded in the North and west of the Great Plains but is multiple-brooded in the Southeast. [4] In the single-brooded range, green-striped grasshoppers' eggs are laid early in the summer season. These eggs hatch later in the same summer. The nymphs will molt three to four times before winter.
Hieroglyphus banian is a species of grasshopper in the family Acrididae. It is a pest of millets such as sorghum, pearl millet, and finger millet in India. [1] It is an annual pest and the eggs require the cycle of dry summer followed by monsoon rains to hatch. The species has an olfactory neuronal pathway remarkably similar to that of ...
