Characterization of two novel polyfunctional mastoparan peptides from the venom of the social wasp Polybia paulista
(Elsevier B.V., 2009-08-01)
Hymenoptera venoms are complex mixtures of biochemically and pharmacologically active components such as biogenic amines, peptides and proteins. Polycationic peptides generally constitute the largest group of Hymenoptera ...
Foraging Behavior of the Swarm-Founding Wasp, Polybia (Trichothorax) sericea (Hymenoptera, Vespidae): Prey Capture and Load Capacity
(California State University, 2009-01-01)
The main component of the protein diet of P. sericea was larvae of Lepidoptera (75.38%), with predominance of the following Families: Noctuidae (30.99%), Hesperiidae (19.01%); Pyralidae (19.01%) and Nymphalidae (11.98%). ...
Two new bradykinin-related peptides from the venom of the social wasp Protopolybia exigua (Saussure)
(Elsevier B.V., 2006-11-01)
Two bradykinin-related peptides (Protopolybiakinin-I and Protopolybiakinin-II) were isolated from the venom of the social wasp Protopolybia exigua by RP-HPLC, and sequenced by Edman degradation method. Peptide sequences ...
Proteomic characterization of the multiple forms of the PLAs from the venom of the social wasp Polybia paulista
(Wiley-Blackwell, 2011-04-01)
The phospholipases A(1) (PLA(1)s) from the venom of the social wasp Polybia paulista occur as a mixture of different molecular forms. To characterize the molecular origin of these structural differences, an experimental ...
Nest defense behavior against ant attacks in post-emergent colonies of wasp Mischocyttarus cerberus (Hymenoptera, Vespidae)
(Springer Heidelberg, 2008-09-01)
The primitive eusocial wasp Mischocyttarus cerberus forms colonies of independent foundation, without morphological differentiation among castes. Ants are natural enemies of the social wasps and defending the wasps' nests ...
Structural and biological characterization of three novel mastoparan peptides from the venom of the neotropical social wasp Protopolybia exigua (Saussure)
(Elsevier B.V., 2005-01-01)
The venom of the Neotropical social wasp Protopolybia exigua(Saussure) was fractionated by RP-HPLC resulting in the elution of 20 fractions. The homogeneity of the preparations were checked out by using ESI-MS analysis and ...
Structural and biological characterization of two novel peptides from the venom of the neotropical social wasp Agelaia pallipes pallipes
(Elsevier B.V., 2004-07-01)
The venom of the neotropical social wasp Agelaia pallipes pallipes was fractionated by RP-HPLC resulting in the elution of seven fractions; the last two were re-fractionated under RP-HPLC by using isocratic elution conditions ...
Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga
(Revista Brasileira de Entomologia, 2019)
Influence of Prey Size on the Capture of Social Wasps (Hymenoptera: Vespidae) by the Orb-Web Spider Nephilengys cruentata
(California State University, 2010-01-01)
The objective of the present study was to evaluate the plasticity of the hunting behavior of the spider Nephilengys cruentata (Araneae: Nephilidae) facing different species of social wasps. Considering that wasps can consume ...
Ultrastructural features of the hypopharyngeal glands in the social wasp Polistes versicolor (Hymenoptera : Vespidae)
(Wiley-Blackwell, 2008-06-01)
The wasps of the genus Polistes have been considered the key to understanding the evolution of social behavior in Hymenoptera. Several studies have shown that the development of organized insect societies was accompanied ...
