Influence of larval density or food variation on the geometry of the wing of Aedes (Stegomyia) aegypti

Abstract: Summarybackground and method Variation in wing length among natural populations of Aedes (Stegomyia) aegypti (L.) (Diptera: Culicidae) is associated with different vectorial capacities. Geometric morphometrics allowed us to use a more powerful estimator of wing size ('centroid size'), as well as to visualize the variation of wing shape, to describe the effects of density or food variation at larval stage on 20 anatomical landmarks of the wing of A. aegypti.results Almost perfect correlations between (centroid)… Show more

“…Other studies have suggested that unlike wing shape, wing size may be a labile trait influenced by temperature (James et al 1997, Gibert et al 2004, Polak et al 2004. However, it is currently difficult to perform a more profound interpretation of wing size data because wing size in culicids is reportedly also influenced by food availability (Jirakanjanakit et al 2007). …”

“…Tais observações e interpretações estão de acordo com a atual teoria sobre as bases biológicas do desenvolvimento alar em Culicidae (Jirakanjanakit et al 2007, 2008, Dujardin 2008b, Morales-Vargas et al 2010. Segundo aqueles autores, a forma alar em Culicidae é determinada por loci genéticos quantitativos, sendo assim, é herdável e minimamente influenciada por fatores epigenéticos.…”

“…Segundo aqueles autores, a forma alar em Culicidae é determinada por loci genéticos quantitativos, sendo assim, é herdável e minimamente influenciada por fatores epigenéticos. Já o tamanho alar, embora potencialmente herdável, pode ser significativamente influenciado por condições ambientais como quantidade de alimento (Jirakanjanakit et al 2007), umidade relativa do ar (Morales-Vargas et al 2010) e temperatura (Scott et al 2000, Tsuda & Takagi 2001.…”

“…Sin embargo, la morfometría tradicional tiene menor poder estadístico que la geométrica debido a que no logra, entre otras cosas, preservar la información espacial de los puntos anatómicos a través de los análisis (15). En Diptera la morfometría geométrica se ha utilizado para estudiar la variabilidad de las cepas de laboratorio de Aedes aegypti y la influencia de la densidad larvaria y las diferentes dietas sobre la arquitectura de las alas de esta misma especie (25,26); pero no conocemos de trabajos publicados en este orden con la intención de apoyar la taxonomía.…”
