Three new phoretic mites from France and Gabon are described. Macrocheles lumareti sp. nov. (from France) was collected on Copris lunaris (Coleoptera, Scarabaeidae). Both M. bertrandi sp. nov. and M. ovoidalis sp. nov. (from Gabon) were collected on Stomoxys calcitrans (Diptera). On the basis of morphological characteristics, M. lumareti and M. bertrandi were identified as belonging to the M. g...

Abstract In the present study we performed a comparative dietary analysis of two predatory birds, Long-eared Owl (Asio otus) and Common Kestrel (Falco tinnunculus) in district Lviv city. We found that are typical small mammal specialists within urban ecosystem. Considering abundance biomass prey, mammals comprise 98.4% Owl’s diet. The species composition coincides almost 50% food intake compari...

Leal et aL have recently reported the isolation of the sex pheromone of the yellowish elongate chafer, Heptophylla picea Motshulsky (Coleoptera, Scarabaeidae, Mololonthinae), an important agricultural pest. especially for tea and fiower production.i) They deduced its structure to be (Z)-7.15-hexadecadien-4-oljde (1> t'rom the mass and infrared spectral data of the pheromone and jts derivatives ...

Oryctes agamemnon arabicus (Coleoptera: Scarabaeidae) is one of the main pests on date palm trees in the United Arab Emirates (UAE). Two mite species were found associated with this beetle: Sancassania sp. (Acari: Astigmata: Acaridae) and Hypoaspis rhinocerotis Oudemans (Acari: Mesostigmata: Laelapidae). Sancassania deutonymphs (hypopi) were phoretic on O. a. arabicus adults and larvae. However...

These experiments determined the magnitude of loads that rhinoceros beetles (Scarabaeidae) can carry and also the metabolic energy required for carrying loads. I hypothesized that, like many other animals, these beetles would have metabolic rates in direct proportion to the total load (body mass plus added mass). Eight beetles (Xylorctes thestalus) walked at 1 cm s-1 on a motorized treadmill en...
