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:
... The elm leaf beetles Pyrrhalta maculicollis (Motschulsky, 1853) and P. aenescens (Fairmaire, 1878) (Chrysomelidae: Galerucinae) are considered to be two separate species that occur in sympatry and synchrony on the same plant host. Conventionally they are distinguished by differences in elytron and pronotum colour, but this variation could just represent intra-specific polymorphism. To test the sta ...

... Tamarind, Tamarindus indica L., is an economically important crop in the dry tropical region of Western Mexico. For more than a decade, damage caused by an insect borer in seeds has been observed. Since 2006, taxonomical identification, biology, hosts, and integrated management of the insect have been studied. In this review, current knowledge of the tamarind seed borer is presented. The beetle is ...
... Movements of the elytra and axillary sclerites were video recorded in tethered flying beetles and in manipulated mounts. Mesothoracic axillary plates are homologues of those in the metathorax. Two anterior axillaries (Ax1, Ax2) fuse together; they are hinged to the third axillary plate (Ax3). In turn, Ax3 is hinged with the elytron. During takeoff, a beetle abducts and highly elevates its elytra ( ...

The functional characterization of an entire class of 17 genes from the red flour beetle, Tribolium castaneum , which encode two families of C uticular P roteins A nalogous to P eritrophins (CPAPs) has been carried out. CPAP genes in T. castaneum are expressed exclusively in cuticle-forming tissues and have been classified into two families, CPAP1 and CPAP3 , based on whether the proteins contain ...
