Completely Randomized Block Design in treatments and replications by selecting place and period.

What type of crop? What type of farmland? Upland or lowland?

Crop is maize. In maize agro-ecology (lowland, midland and highland) at field and around home or different habitat.

Okay,your general collections will be done with a sweepnet, and may also include other methods such as yellow sticky trap, pitfall and light traps at night, since you are interested in the guilds of the insects. You may not know your insects guilds/categories until after identification. So it is better to explore more collection methods for robust data. You may also look out for cocoons you may be lucky to see parasitoids as well. While you read more peer reviewed literatures tailored to your research, ensure to have replicates of your collections. Best of luck!

Thank You! to your help@

Capturing is one thing, but the real work is in identifying the large amount of collected arthropods. If you have trained staff, there's no problem. When I started this work (in the eighties) I had to train assistants myself. This was in Burkina Faso. At least one of them was later hired by the WHO for their research on insect vectors. Many overlook this issue when starting, and end up with poor data.

So true, the real work is in insect identification, cumbersome but very interesting if you are able to get the keys and sort them on time.

Dear Dr. Muluken,

Thank you for suggestion and advice!

I look at.
