They act as minor pests for some crops and as major pests for others under certain conditions in several parts of the world. The present work reviews the most important agronomic impacts of various beetle species in different African, Asian, European and American countries, both the old world and new world, whether it has direct impact by damaging the foliage and feeding on crops or indirect effect by suppressing the populations of pollinators. Many host plants of the blister beetles belonging to various families were reported. The influenced insect biodiversity (bees and grasshoppers) by blister beetles were discussed. With regard to the management, different mechanical, physical, cultural, behavioral, chemical (synthetic insecticides and botanical insecticides), biological (predators and natural enemies), microbial (fungi, bacteria and nematodes) and genetic measures in different parts of the world were reviewed. Key words: Host plants, adults, triungulins, insect fauna, bees, grasshoppers, natural enemies, management techniques, control measures. INTRODUCTION The Meloidae (blister beetles or oil beetles) is a beetle 1922; Coleman, 1983; Ali et al., 2005). Plant-host families family (order Coleoptera) with about 120 genera and of some Nearctic meloid beetles are Asclepiadaceae, 3000 species.
