Abstract:
... Incoming solar, net, and reflected radiation, wind velocity, relative humidity, and temperatures at various levels above and below an open desert surface were recorded simultaneously at 30—minute intervals for a 3—day period. Concurrent measurements were also made of arthropod burrow temperatures and relative humidities, scorpion body temperatures, and body and subelytral temperatures of tenebrion ...

Abstract:
... Adult red palm weevils (Rhynchophorus ferrugineus Oliv.) were labeled by topical application of cerium chloride (CeCl_3) in 90% ethanol. Marked adults were detectable by assay of radiocerium following neutron activation of excised elytra. No significant loss of cerium from marked insects occurred over prolonged periods or after repeated washing with water. This marking technique has potential appl ...

Abstract:
... Ultraviolet reflectance is a widely distributed phenomenon among certain families of Coleoptera. It is so far found to occur in Carabidae, Scarabaeidae, Buprestidae, Elateridae, Tenebrionidae, Cerambycidae, Anthribidae and Curculionidae. Of more than 100 species examined, 70 were found to possess UV reflectant structures. Reflection is almost always from pigments contained within microtrichia or o ...

Abstract:
... In order to determine whether natural levels of food for adult bombardier beetles (Brachinus) were low enough to lead to reduced reproduction and survival, laboratory and field experiments were conducted in southeastern Arizona, USA. In the laboratory, feeding affected reproduction over a period of months, but had no detectable effect on short—term egg production. Females did not reproduce until t ...

Abstract:
... Oreina cacaliae (Coleoptera, Chrysomelidae) produces in its elytral and pronotal defensive secretion seneciphylline N‐oxide together with small amounts of another pyrrolizidine alkaloid tentatively identified as senecionine N‐oxide. This is a strong departure from the chemical composition of the defensive secretions in related species, characterized by complex mixtures of cardenolides, synthesized ...
