A Contribution to the Ecology and Biology of Tree Hole Breeding Mosquitoes of Panama1

Sampling the Egg Population

“…To attract ovipositing females that lay eggs in these habitats bamboo pots have a small hole bored in the side near the top which is covered by a lid (Carpenter et al, 1952;Galindo et al, 1951Galindo et al, , 1955. The pots are sampled by removing the top and tipping the contents into a white enamel bowl.…”

“…When gourds, which have been used in Nigeria to study mosquitoes breeding in tree-holes, were repeatedly soaked a few Aedes eggs failed to hatch until the 7th soaking. Similarly, in Panama a small number of eggs of Haemagogus species in bamboo pots remained unhatched until the 10th flooding (Galindo et al, 1955). Buxton & Breland (1952) soaked tree-hole litter 13 times and obtained an egg hatch of Aedes triseriatus on 12, and of Aedes zoosophus on 9 occasions.…”

“…Water-filled sections of bamboo, usually termed bamboo pots or cups, have commonly been used as artificial oviposition sites to attract mosquitoes that breed in tree-holes and bamboo (Bang et al, 1979;Causey & dos Santos, 1949;Corbet, 1963Corbet, , 1964aDunn, 1927;Galindo et al, 1951Galindo et al, , 1955Harris, 1942;Harrison et al, 1972;Laarman, 1958;Lambrecht & Zaghi 1960;Lounibos, 1979Lounibos, , 1981Petersen & Willis, 1971;Philip, 1933;Sempala, 1983;Service, 1965Service, , 1970Yates, 1979). Suitable bamboo may not grow in areas in which the pots are to be used.…”

Sampling Methods for Water‐Filled Tree Holes and Their Artificial Analogues

“…However, tree hole height can affect community properties and distributions of some species (Galindo et al 1951(Galindo et al , 1955Lounibos 1981). In Panama, for example, species richness in tree holes generally declines with increasing height above the ground (Yanoviak 1999b).…”

Nova técnica para o estudo da fauna de mosquitos (Diptera: Culicidae) em internódios de bambus, com resultados preliminares

“…Os mosquitos podem efetuar postura em bambus cortados ou furados. Em bambus furados, em que há predominância de Sabethes (Culicinae: Sabethini), os ovos são pouco resistentes à dessecação 3 . O comportamento de postura de Sa.…”
