Natural Insecticides and Cricket Survival

Medium
Natural Insecticides and Cricket Survival | Science Fair Projects | STEM Projects
Which plant-based insecticide works best against crickets? Synthetic pesticides raise safety concerns. Three natural options might offer a safer way to control pests. You place 15 crickets in each of 12 containers. Three containers get pyrethrum. Three get wormwood and three get rosemary. The last three serve as a control with no treatment. You check every two hours for 20 hours and count survivors. One of the three natural treatments proves far more effective than the others.

Hypothesis

The hypothesis is that Wormwood will be most effective against the crickets.

Science Concepts Learned

Biopesticide

Pyrethrum, wormwood, and rosemary all come from natural sources and can act as pest-control sprays. This experiment puts all three to the test against crickets. Fifteen crickets go into each of twelve containers, with each natural treatment assigned to three containers and three left as a control. Checking every two hours over 20 hours reveals which option proves far more effective than the others.

Pest Control

Some plants can work as bug killers. In this test, you try three of them on crickets. You put 15 crickets in each box, then add pyrethrum, wormwood, or rosemary. You check every two hours to count how many are still alive. One of the three works much better than the rest.

Method & Materials

You will measure out different amounts of Pyrethrum, Wormwood, and Rosemary and put them in containers with crickets. Then you will observe the results over time to see which one works best.
You will need one 1oz Pyrethrum, one 1oz Wormwood Powder, one 1oz Rosemary, 12 Containers for containing the crickets, and 1 Week for mail orders to arrive.

Results

The results indicated that the hypothesis should be rejected because the pyrethrum was far more effective than the Wormwood. This experiment showed that Pyrethrum could be used to more effectively control crickets.

Why do this project?

This science project is interesting because it explores the possibility of using natural insecticides instead of synthetic ones, which can be harmful to the environment.

Also Consider

Experiment variations to consider include testing different amounts of each insecticide, testing different types of insecticides, and testing different types of crickets.
