Spider venom: enhancement of venom efficacy mediated by different synergistic strategies in Cupiennius salei.
Besides the power of the chelicerae, synergistic interactions between different components in the venom of Cupiennius salei ensure the hunting success of this spider. The main components of the venom were tested alone or in combination according to their physiological venom concentrations in Drosophila bioassays. The high K+ ion content of the venom synergistically increases the insecticidal ac...
متن کاملNeurogenesis in the spider Cupiennius salei.
To uncover similarities and differences in neurogenesis in arthropod groups, we have studied the ventral neuroectoderm of the spider Cupiennius salei (Chelicerata, Aranea, Ctenidae). We found that invaginating cell groups arose sequentially, at stereotyped positions in each hemisegment and in separate waves, comparable with the generation of neuroblasts in Drosophila. However, we found no evide...
متن کاملNeurogenesis in the spider Cupiennius salei
The phylum arthropoda comprises four classes: myriapoda, crustacea, insecta and chelicerata. The monophyly or polyphyly of the arthropoda has been questioned, as has the relationship of the individual classes to each other. The principle difficulty involves deciding which of the morphological similarities that unite these groups are the result of close evolutionary relationships and which repre...
متن کاملIsolation, N-glycosylations and Function of a Hyaluronidase-Like Enzyme from the Venom of the Spider Cupiennius salei
STRUCTURE OF CUPIENNIUS SALEI VENOM HYALURONIDASE Hyaluronidases are important venom components acting as spreading factor of toxic compounds. In several studies this spreading effect was tested on vertebrate tissue. However, data about the spreading activity on invertebrates, the main prey organisms of spiders, are lacking. Here, a hyaluronidase-like enzyme was isolated from the venom of the s...
متن کاملDifferent functions of different eye types in the spider Cupiennius salei.
The Central American hunting spider Cupiennius salei Keys relies mainly on its mechanosensory systems during prey-catching and mating behaviour. The behavioural relevance of its eight eyes has not been studied before, although their optics and sensitivity suggest highly developed visual capabilities. The visual system was examined in a twofold simultaneous-choice experiment. Two targets were pr...
