Rate of soil egestion by larvae of Hylamorpha elegans (Burm.) and Phytoloema hermanni Germ. (Coleoptera: Scarabaeidae).

Differential Susceptibility of Japanese Beetle, Oriental Beetle, and European Chafer (Coleoptera: Scarabaeidae) Larvae to Five Soil Insecticides

Larval morphology of Aphodius sus (Herbst) and A. variicolor Koshantschikov (Coleoptera: Scarabaeidae: Aphodiinae)

Morphological descriptions and illustrations are presented for third-instar larvae of two species of the scarab beetle genus Aphodius Illiger: Aphodius (Heptaulacus) sus (Herbst) and A. (Chilothorax) variicolor Koshantschikov. These descriptions are based on material collected in European Russia. Larvae were collected from the soil with no association to dung although the adults of the same spe...

Identification of a putative Mexican strain of Serratia entomophila pathogenic against root-damaging larvae of Scarabaeidae (Coleoptera).

The larvae of scarab beetles, known as "white grubs" and belonging to the genera Phyllophaga and Anomala (Coleoptera: Scarabaeidae), are regarded as soil-dwelling pests in Mexico. During a survey conducted to find pathogenic bacteria with the potential to control scarab larvae, a native Serratia sp. (strain Mor4.1) was isolated from a dead third-instar Phyllophaga blanchardi larva collected fro...

Ecology and Behavior Acoustic Detection of Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) and Oryctes elegans (Coleoptera: Scarabaeidae) in Phoenix dactylifera (Arecales: Arecacae) Trees and Offshoots in Saudi Arabian Orchards

Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) larvae are cryptic, internal tissue-feeding pests of palm trees that are difficult to detect; consequently, infestations may remain hidden until they are widespread in an orchard. Infested trees and propagable offshoots that develop from axillary buds on the trunk frequently are transported inadvertently to previously uninfested a...

Transformation and Mineralization of Organic Matter by the Humivorous Larva of Pachnoda ephippiata (Coleoptera: Scarabaeidae) Dissertation zur Erlangung des Doktorgrades der Naturwissenschaften

In order to investigate whether microbial biomass and its residues are nutrient and energy sources for humivorous beetle larvae, we carried out feeding trials using soil supplemented with C-labeled fungal biomass (Penicillium chrysogenum), bacterial biomass (Bacillus megaterium), fungal or bacterial structural polysaccharide (chitin, peptidoglycan), bacterial protein, or cellulose, taking the l...
