Insects or Insecta from Latin insectum are pancrustacean hexapod invertebrates and the largest group within the arthropod phylum. Definitions and circumscriptions vary; usually, insects comprise a class within the Arthropoda. As used here, the term Insecta is synonymous with Ectognatha. Insects have a chitinous exoskeleton , a three-part body head , thorax and abdomen , three pairs of jointed legs , compound eyes and one pair of antennae. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms.

The practice of rice crop cultivation will affect the trophic structure and the diversity of insects that are formed. One of the common cultivation practices carried out by farmers was the control of pests by using pesticides. This study aimed to find out which pest management strategies that are effective in maintaining environmental health and understanding how natural enemies were affected by the application of synthetic pesticides. The first treatment was paddy field with integrated pest management IPM , the second treatment was conventional rice field with a technique of chemical pest management C-T , while the third treatment was mixed pest management M-T. Insect sampling was conducted using sweep net, pitfall trap, and direct observation for 10 weeks after planting.

Insect , class Insecta or Hexapoda , any member of the largest class of the phylum Arthropoda , which is itself the largest of the animal phyla. Insects have segmented bodies, jointed legs, and external skeletons exoskeletons. Many insects, however, are beneficial from a human viewpoint; they pollinate plants, produce useful substances, control pest insects, act as scavengers, and serve as food for other animals see below Importance. Furthermore, insects are valuable objects of study in elucidating many aspects of biology and ecology. Much of the scientific knowledge of genetics has been gained from fruit fly experiments and of population biology from flour beetle studies. Insects are often used in investigations of hormonal action, nerve and sense organ function, and many other physiological processes. Insects are also used as environmental quality indicators to assess water quality and soil contamination and are the basis of many studies of biodiversity.
