Community Structure and Composition of Social Wasps (Hymenoptera: Vespidae) in Different Vegetation Types in Sao Paulo, Brazil
(Univ Estadual Feira Santana, 2020-09-01)
Social wasps participate in food webs, act as biological control agents in small crops and the natural environment, and act as potential pollinators. The objective of this study was to carry out an inventory of social wasps ...
Colony membership is reflected by variations in cuticular hydrocarbon profile in a Neotropical paper wasp, Polistes satan (Hymenoptera, Vespidae)
(Funpec-editoraRibeirao PretoBrasil, 2007)
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%). ...
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 ...
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 ...
Ultramorphological analysis of the venom glands and their histochemical relationship with the convoluted glands in the primitive social paper wasp Polistes versicolor (Hymenoptera: Vespidae)
(Centro de Estudos de Venenos e Animais Peçonhentos, 2005-06)
The venom glands are part of the most important defense weapon in Aculeata: the venom apparatus. The arrangement of these glands can vary among species, but in general they are composed of long secretory tubules connected ...
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 ...
