The Grasshopper’s Dilemma

But as he later was reminded, God has not given us a spirit of fear. And he was not doomed to live a grasshopper existence just because his feelings told him to.

Moreover, grasshopper dilemmas are often built on scarcity thinking. 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.

This ensures wide dispersal of the fungal spores liberated from the corpse. It is being investigated for possible use as a microbial insecticide for locust control. It has to be consumed by mouth and is the basis for a bait-based commercial microbial pesticide. Various other microsporidians and protozoans are found in the gut. Anti-predator adaptation Grasshoppers exemplify a range of anti-predator adaptationsenabling them to avoid detection, to escape if detected, and in some cases to avoid being eaten if captured.

Grasshoppers are often camouflaged to avoid detection by predators that hunt by sight; some species can change their coloration to suit their surroundings. Stick grasshoppers Proscopiidae mimic wooden sticks in form and coloration. Dictyophorus productus Pyrgomorphidae is a "heavy, bloated, sluggish insect" that makes no attempt to hide; it has a bright red abdomen. A Cercopithecus monkey that ate other grasshoppers refused to eat the species.

Lubber grasshopper, Titanacris albipeshas deimatically coloured wings, used to startle predators.

Painted grasshopper, Dactylotum bicolordeters predators with warning coloration. Spotted grasshopper, Aularches miliarisdefends itself with toxic foam and warning colours. The seemingly static scene is animated by a "grasshopper on the table that looks about ready to spring", according to the gallery curator Betsy Wieseman, with other invertebrates including a spider, an ant, and two caterpillars. The film Beginning of the End portrayed giant grasshoppers attacking Chicago. 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. A single season of drought is not normally sufficient to stimulate a major population increase, but several successive dry seasons can do so, especially if the intervening winters are mild so that large numbers of nymphs survive.

Although sunny weather stimulates growth, there needs to be an adequate food supply for the increasing grasshopper population. This means that although precipitation is needed to stimulate plant growth, prolonged periods of cloudy weather will slow nymphal development. The study sites were selected within Calabar South and Calabar Municipality.

Subsistence farming was the major practice in all the farm sites. The major crops cultivated were: Talinum triangulare waterleafTelfairia occidentalis fluted pumpkinZea mays maizeAbelmoschus esculentus okraSpinacea oleracea spinachSolanum melongena garden egg and Manihot esculenta cassava.

Grasshoppers were collected weekly from all study sites for 4 months August to November, Samples collected were placed in killing jars, labelled appropriately and transported to the Department of Zoology and Environmental Biology laboratory for sorting. Samples were identified using keys of Medler -Insects of Nigeria.

Voucher specimens were kept for reference purposes. Eleven grasshopper species were collected and reported in Table 1. Tettigonia viridissima, Scudderia mexicana, Tylopsis sp. Of these, Tettigonia viridissima and Acridaturita sp. Spathosterrium pygmaeum recorded the highest relative abundance, The grasshopper species in open plot and their relative abundance in the total sample were: While the dominant species in farmland were: The population of grasshoppers was higher in relative abundance in open fallow plots than cultivated areas.

Some portions of the Unical farm are deliberately left fallow to improve the soil fertility so it could be used as practical and demonstration farms by students. The Margaret Ekpo environment is highly restrictive due to its proximity to the Calabar international airport. These plots had fallowed and were characterised by minimal human disturbances and over grown weeds which may have attracted higher number of grasshoppers.

This is in agreement with the studies of Van Wingerden et al.

It is likely that these anthropogenic activities deprive grasshoppers of their host plant which may encourage their migration to undisturbed areas in search of alternative food source.
