Observations were made in 2016 in apple tree plantations, corn crops and cabbage crops belonging to the Vasile Adamachi farm, Iasi, Iasi County. The purpose of the paper was to compare the entomofauna by a number of 3 different crops as well as agroecosystem technology and conditions. The material was harvested using Barber soil traps from June until September inclusive. The collected material was cleaned of vegetal remains and was then prepared for identification at insect level. The analysis of the collected material shows that the specimens collected belong to the Hexapoda Class, with several orders of insects and the Arachnida Class, the Aranea order. Most of them belong to the Insecta class. The orders to which the species are collected are: Coleoptera, Heteroptera, Hymenoptera, Diptera, all of the Hexapoda class. Regarding the abundance of entomofauna on crops, it is found that most of the cabbage crops were collected (126) followed by apple crops (123) and then corn cultures (107).Â
