• Maize is among the world’s three most important cereal crops. It is Myanmar’s second most important crop with more than one million acres planted annually. A total number of (3210) individuals was accounted for 18 species of insects, distributed among 17 genera 14 families, and six orders, and collected from maize plantations, Min Hla Township, Magway Region from January to December 2022. Among the recorded species, 13 species were identified as pests and the other five species as beneficial or predatory insects. In the present study, the maximum number of species recorded in order Hemiptera was represented by five species (33.33%) while, the minimum number of species Orthoptera, Neuroptera, and Hymenoptera recorded only one species (6.67%) respectively from study site I (Malun Village). In study site II (Pan Taw Pyin Village) the maximum number of species recorded in order Hemiptera was represented by seven species (38.88%), while the minimum number of species in Orthoptera, Neuroptera, and Hymenoptera recorded only one species (5.56%) respectively. In study site I, the maximum number of individuals was recorded in the order Lepidoptera represented by (739) individuals (51.71%), while the minimum number of individuals in Orthoptera (21) individuals (1.47%) were recorded during the study period. The maximum numbers of individuals were collected in order Lepidoptera was represented by (815) individuals (45.76%), the minimum number of individuals were collected in Orthoptera (8) individuals (0.45%) were recorded in study site II. During the study period, Lepidopterans species are predominant on maize plantations in two study sites.
