  1. Effects of Poison Concentration to the Common Cricket Presented by Erin Hill

  2. Acheta domesticus • Adults are 3/4” long • 3 dark bands on the head • Body is light yellow-brown • Omnivorous • Destroy silk, wool, paper, rubber

  3. Classification • Kingdom: Animalia • Phylum: Arthropoda • Class: Insecta • Order: Grylloptera (Orthoptera) • Family: Grillidae • Genus: Acheta • Species: Acheta domesticus

  5. Troublesome Pests? • More annoying for their chirping than for their destruction • BUT – representative of insects in general which include: • Ants • Bees/wasps • Cockroaches

  6. Small Sacrifices • Available at most pet stores (food) • Inexpensive • Easy to raise • Just as susceptible to pesticides and bug sprays as other insects

  7. The Question: • Which type of chemical is the best killer? • Spray • Foam • Jet

  8. Materials • About 80 crickets • 12oz. Jar cricket food (at right) • 2 gallon holding tank • Small plastic cups for testing • Pesticides

  9. Chemicals • Raid House & Garden • Hold can 12” away from surface • NOT used of edible crops • Active Ingredients: • D-cis, trans allethrin 0.239% • 3-phenoxylbenzyl d-cis and trans 2,2-dimethyl-3-cyclopropanecarboxylate 0.096%

  10. Chemicals (con’t) • Repel Sportsmen Formula • Hold can 6-8” from skin • Active Ingredient: • N, N-diethyl-m-toluamide (DEET) and other isomers 29%

  11. Chemicals (con’t) • Ortho Hornet & Wasp Killer • Jet carries 6-8 feet • Cancelled 1987 • Active Ingredient: • Pyrethrins .10% - (carcinogenic) • Piperonyl butoxide .20% • N-octyl bicycloheptene dicarboximide .33% (possible carcinogen)

  12. Procedure • Capture single cricket in plastic cup • Cover cup with paper towel, leaving a hole for spray application • Deliver one quick spray to cup interior • Register amount of time from spray to cricket death

  13. Procedure (con’t) • “Death” was accepted to be the time when the prone insect stopped twitching • Repeat for 10 crickets with each chemical • Place plastic cups/dead crickets in plastic bag for city disposal

  14. Results

  15. Conclusions • Raid House & Garden • Produced a thick, sticky foam that trapped the crickets • Crickets twitched for quite some time before finally dying • Death took almost 2 minutes in some cases

  16. Conclusions (con’t) • Repel Sportsmen Formula • Produced fine mist in whole cup • Relatively short time to die, but lots of struggling and twitching • Dead were highly contorted and twisted

  17. Conclusions (con’t) • Ortho Hornet & Wasp Killer • Produced thin jet of chemical • Almost instantaneous death with few exceptions • Crickets didn’t have time to twitch

  18. In The End … • It was concluded that while the Ortho Hornet & Wasp Killer was the most harmful to humans and non-target organisms, it was definitely the most effective of the three chemicals tested • In close second was the Repel Sportsmen Formula though it was not meant for killing insects, only repelling them
