Pasture, grain, forage, vegetable and other crops can be affected. Grasshoppers often bask in the sun, and thrive in warm sunny conditions, so drought ...
Normally, these grasshoppers are innocuous, their numbers are low, and they do not pose a major economic threat to agriculture. However, under suitable conditions of drought followed by rapid vegetation growth, serotonin in their brains triggers dramatic changes: they start to breed abundantly, becoming gregarious and nomadic (loosely described ...
They can be used to address the issue of depleted agricultural lands as they don't need much space to be reared as compared to livestock. Additionally, food waste is a significant issue with 1/3 of food being wasted globally; Since insects can eat food waste, and they require less feed, they are a good option to address food waste.

Within an ecological food chain, consumers are categorized into primary consumers, secondary consumers, and tertiary consumers. [3] Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).

Many grasshoppers, such as individuals from the family Acrididae, have diets consisting primarily of plants from the family Poaceae. [4] Although humans are not graminivores, we do get much of our nutrition from a type of grass called cereal, and especially from the fruit of that grass which is called grain. [5]
[2] [5] This grasshopper can become a pest of grains, and includes soybeans, alfalfa, wheat, and barley, among others. [11] Melanoplus species eat grasses of all kinds, as well as leafy and grassy agricultural crops and garden plants. They feed on the leaves, and sometimes fruit, flowers, and buds, as well as tree bark.
