What are the diseases that grasshoppers are affected by?

Grasshoppers are affected by diseases caused by bacteria, viruses, fungi and protozoa. The bacteria Serratia marcescens and Pseudomonas aeruginosa have both been implicated in causing disease in grasshoppers, as has the entomopathogenic fungus Beauveria bassiana. This widespread fungus has been used to control various pest insects around the world, but although it infects grasshoppers, the infection is not usually lethal because basking in the sun has the result of raising the insect's temperature above a threshold tolerated by the fungus. The fungal pathogen Entomophaga grylli is able to influence the behaviour of its grasshopper host, causing it to climb to the top of a plant and cling to the stem as it dies. This ensures wide dispersal of the fungal spores liberated from the corpse.

What is grasshopper?

For other uses, see Grasshopper (disambiguation). Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is probably the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago.

What suborder are grasshoppers in?

Grasshoppers belong to the suborder Caelifera. Although "grasshopper" is sometimes used as a common name for the suborder in general, some sources restrict it to the more "advanced" groups. They may be placed in the infraorder Acrididea and have been referred-to as "short-horned grasshoppers" in older texts to distinguish them from the also-obsolete term "long-horned grasshoppers" (now bush-crickets or katydids) with their much longer antennae. The phylogeny of the Caelifera, based on mitochondrial ribosomal RNA of thirty-two taxa in six out of seven superfamilies, is shown as a cladogram. The Ensifera (crickets, etc. ), Caelifera and all the superfamilies of grasshoppers except Pamphagoidea appear to be monophyletic.

How do grasshoppers flex their legs?

First, the grasshopper fully flexes the lower part of the leg (tibia) against the upper part (femur) by activating the flexor tibiae muscle (the back legs of the grasshopper in the top photograph are in this preparatory position).

How do grasshoppers jump?

Grasshoppers jump by extending their large back legs and pushing against the substrate (the ground, a twig, a blade of grass or whatever else they are standing on); the reaction force propels them into the air. They jump for several reasons; to escape from a predator, to launch themselves into flight, or simply to move from place to place. For the escape jump in particular there is strong selective pressure to maximize take-off velocity, since this determines the range. This means that the legs must thrust against the ground with both high force and a high velocity of movement. A fundamental property of muscle is that it cannot contract with high force and high velocity at the same time. Grasshoppers overcome this by using a catapult mechanism to amplify the mechanical power produced by their muscles.

How many segments are there in a grasshopper?

The abdomen has eleven segments, the first of which is fused to the thorax and contains the tympanal organ and hearing system. Segments two to eight are ring-shaped and joined by flexible membranes. Segments nine to eleven are reduced in size; segment nine bears a pair of cerci and segments ten and eleven have the reproductive organs. Female grasshoppers are normally larger than males, with short ovipositors. The name of the suborder "Caelifera" comes from the Latin and means chisel-bearing, referring to the shape of the ovipositor.

What is the name of the worm that infects grasshoppers?

The grasshopper nematode ( Mermis nigrescens) is a long slender worm that infects grasshoppers, living in the insect's hemocoel. Adult worms lay eggs on plants and the host becomes infected when the foliage is eaten. Spinochordodes tellinii and Paragordius tricuspidatus are parasitic worms that infect grasshoppers and alter the behaviour of their hosts. When the worms are sufficiently developed, the grasshopper is persuaded to leap into a nearby body of water where it drowns, thus enabling the parasite to continue with the next stage of its life cycle, which takes place in water.

How do grasshoppers affect the landscape?

One lone grasshopper can't do too much harm, although it eats about half its body weight in plants each day—but when locusts swarm, their combined feeding habits can completely defoliate a landscape, leaving farmers without crops and people without food. In 2006, researchers reported an earlier study estimating that damage to forage crops amounting to $1.5 billion was caused annually by grasshoppers. 1  In 1954, a swarm of Desert locusts ( Schistocerca gregaria) consumed over 75 square miles of wild and cultivated plants in Kenya. 2 

What suborder are grasshoppers in?

Jumping herbivores with shorter antennae are grouped into the suborder Caelifera, while their longer-horned brethren ( crickets and katydids) belong to the suborder Ensifera . 2. Grasshoppers Have Ears on Their Bellies. The grasshopper's auditory organs are found not on the head, but rather, on the abdomen.

How do grasshoppers jump?

How do these insects jump so far? It's all in those big, back legs. A grasshopper's hind legs function like miniature catapults. In preparation for a jump, the grasshopper contracts its large flexor muscles slowly, bending its hind legs at the knee joint. A special piece of cuticle within the knee acts as a spring, storing up all the potential energy. The grasshopper then relaxes its leg muscles, allowing the spring to release its energy and fling the insect into the air.

Why do grasshoppers have wings?

Because grasshoppers have such powerful jumping legs, people sometimes don't realize that they also have wings. Grasshoppers use their jumping ability to give them a boost into the air but most are pretty strong fliers and make good use of their wings to escape predators.

What does it mean when a grasshopper stridulates?

Most grasshoppers stridulate, which simply means that they rub their hind legs against their forewings to produce their trademark tunes. Special pegs on the inside of the hind leg act like a percussion instrument of sorts when they come in contact with the thickened edge of the wing. The band-winged grasshoppers crepitate or loudly snap their wings as they fly.

When did grasshoppers first appear?

Modern-day grasshoppers descend from ancient ancestors that lived long before dinosaurs roamed the Earth. The fossil record shows that primitive grasshoppers first appeared during the Carboniferous period, more than 300 million years ago. Most ancient grasshoppers are preserved as fossils, although grasshopper nymphs (the second stage in the grasshopper lifestyle after the initial egg phase) are occasionally found in amber.

Why do grasshoppers spit liquid?

Scientists believe this behavior is a means of self-defense, and the liquid helps the insects repel predators.

What do grasshoppers eat?

Most grasshoppers are polyphagous, eating vegetation from multiple plant sources, but some are omnivorous and also eat animal tissue and animal faeces. In general their preference is for grasses, including many cereals grown as crops. The digestive system is typical of insects, with Malpighian tubules discharging into the midgut. Carbohydrates are digested mainly in the crop, while proteins are digested in the ceca of the midgut. Saliva is abundant but largely free of enzymes, helping to move food and Malpighian secretions along the gut. Some grasshoppers possess cellulase, which by softening plant cell walls makes plant cell contents accessible to other digestive enzymes.

How do grasshoppers make sounds?

Not exactly, Grasshoppers make a sound similar to maracas (Rhythmic Clicking), using their large “knees” of the hind legs and tapping them against their wings while in flight.

Gardeners and grasshoppers are rarely on friendly terms. A grasshopper outbreak (when swarms of insects hatch and begin feeding at the same time) can devastate a small garden in a few hours. Huge appetites combined with the ability to easily jump or fly from plant to plant make grasshoppers one of the most destructive garden pests. They are also one of the toughest insects to control because they move so quickly, thanks to their big back legs and active wings.
