His interests in the Scarabaeidae have created a new era in Mexican faunal studies, along with his students and colleagues. Since that time he has continued his studies and to describe new species. Several papers in the present volume attest to the need for descriptions, mentioning new species in numbers over 100. Many more probably await discovery. In this book, Melolonthidae is considered a family, with the Dynastinae a subfamily of it.
Adults do cause foliar damage to a wide variety of trees, but the most damaging stage is the larva.
Larvae are reported as pests on sesame, rice, broccoli, sugarcane, onions, asparagus, beans, corn, potatoes, sorghum, tomatoes, other vegetables, pastures, and cultivated ornamental flowers. This roundtable is an important contribution to our understanding of these soil insects. Continued studies should be encouraged and the results published as rapidly as this volume.
