He hopes this knowledge will help scientists identify which microbial control agents would be most effective to use against this seasonal pest. Srygley plans to further study this phenomenon by rearing carbohydrate- and protein-deficient crickets in the laboratory. Details of this study have been published in Ecological Entomology. Similarly, crickets lacking enough carbohydrates in their diet were deficient in an enzyme involved in fighting bacteria. They found insects lacking enough protein in their diets were deficient in an enzyme key to combating fungi.

Based on these findings, it seems ideal to apply biocontrol agents during the insect's immature or early-adult life stages.

At the adult stage, the Mormon cricket no longer molts and therefore no longer needs to compromise its immune system. For miles they covered the ground and roads as far as the eye could see, a seething, blackish-brown quivering carpet. I ran into a few of these on my Walkabout. These guys also aren’t crickets but Shield-backed Katydids. Enzyme assays have also revealed that the immune system is weakened with each molt, when the insect sheds its exoskeleton as it grows larger. Mormon Cricket (Anabrus simplex) Ah, the Mormon cricket. The researchers have found that a young Mormon cricket will sacrifice the growth of its immune system to allocate more resources for physical growth. ARS is USDA's principal intramural scientific research agency. This will help identify when biocontrol agents will be most effective in curbing infestations. They also pose a danger to drivers when their crushed bodies build up on highways and create road slicks.Įntomologist Robert Srygley, with the Agricultural Research Service (ARS) Northern Plains Agricultural Research Laboratory in Sidney, Mont., is studying the Mormon cricket's immune system to determine its most vulnerable stage during development.

Cricket infestations can wipe out acres of grasses and field crops through their voracious feeding. Like its grasshopper cousin, the Mormon cricket plagues farmers and ranchers in the Northern Plains during the summer.
