Os insetos como agentes polinizadores da mangueira

The authors study the insect population that visit the mango trees and search for their pollinizing activity. Prior operations showed that very few bees (Apis mellifera) visited the flowers of mango trees. It was known that the percentage of fecundation is low (Simão 1955), Popenoe (1929), Spencer and Kennard (1955), Lynch and Mustard (1955), Ruehle and Ledin (1955), so that the authors wented to Know if insects could be responsible for this. Insects were collected from mango trees, belonging to 10 orders, which, on the whole are not pollinizing agents. Bees were not collected, 21% were Hymenoptera, 20% were Diptera, 13% Hemiptera, 10% Coleoptera, 3% Blattariae and smoller percentages belonged to other orders.

Notas e descrições em Parandrini (Coleoptera, Cerambycidae, Parandrinae)

The genus Parandra is reviewed and four genera are recognized: Parandra Latreille, 1804, Neandra Lameere, 1912, stat. nov., Archandra Lameere, 1912, stat. nov. and Acutandra gen. nov. The genus Parandra is subdivided in two subgenera: Parandra (Parandra) s. str. and Parandra (Birandra) subgen. nov. The geographical distribution of P. (P.) laevis Latreille, 1804 is commented and the probable synonymy between P. cubaecola Chevrolat, 1862 and P. (P.) cribrata Thomson, 1861 is discussed. New species described: P. (P.) tavakiliani from Puerto Rico and P. (Birandra) mariahelenae from Jamaica. New combinations: Neandra brunnea (Fabricius, 1798), Neandra marginicollis (Schaeffer, 1929), Archandra caspia (Ménétriès, 1832), Acutandra punctatissima (Thomson, 1861), A. degeeri (Thomson, 1867), A. murrayi (Lameere, 1912), A. araucana (Bosq, 1951), A. ubitiara (Santos-Silva & Martins, 2000), all from Parandra. Keys to genera of Parandrini, subgenera of Parandra and American species of Parandra and Acutandra are added.
