Enzymatic variability among venoms from different subspecies of Apis mellifera (Hymenoptera: Apidae)
(2005-06-01)
The enzymatic variability was analyzed in venom extracts from bees reared in different colonies of the Africanized, A. m. ligustica and A. m. carnica subspecies. The implications of this variation focused on the biochemistry ...
Study of the venom glands in Ectatomma quadridens (Hymenoptera: Formicidae). Evolutionary hypothesis in subfamily ponerinae
(2005-06-01)
The venom glands of worker ants of the species Ectatomma quadridens morphologically resemble an elongated sac or reservoir ending in a narrower portion that has the function of releasing the secretion to the exterior. Two ...
Bioinsecticide action of the venom of Africanized bees Apis mellifera Linnaeus 1758 (Hymenoptera: Apidae): I - The most susceptible age of Diatraea saccharalis Fabricius 1794 (Lepeletier: Pyralidae) eggs to the venom action
(1996-01-01)
The present paper aimed at testing the action of non-lyophilized venom of Africanized bees Apis mellifera through topical applications on Diatraea saccharalis egg masses. The CL50, DL50 and the most susceptible age of eggs ...

A comparative study of protein and enzymatic activity in venoms of some common wasps (Hymenoptera: Vespidae) from São Paulo State
(2004-10-06)
The Hymenoptera Aculeata venoms, with few exceptions, have been poorly studied and characterized. Nevertheless, they have raised increasing interest due to their medical importance, since accidents with these insects are ...

Insect venom phospholipases A1 and A2: Roles in the envenoming process and allergy
(2019-02-01)
Insect venom phospholipases have been identified in nearly all clinically relevant social Hymenoptera, including bees, wasps and ants. Among other biological roles, during the envenoming process these enzymes cause the ...
Chemometric analysis of Hymenoptera toxins and defensins: A model for predicting the biological activity of novel peptides from venoms and hemolymph
(2011-09-01)
When searching for prospective novel peptides, it is difficult to determine the biological activity of a peptide based only on its sequence. The trial and error approach is generally laborious, expensive and time consuming ...
