“…For example, Lushai et al (2002) discriminated 14 genotypes of Sitobion avenae among 216 clones using only one primer in a site in England. There is only one report of gamic morphs of S. graminum occurring at field condition in Brazil (Cabette, 1995). However, this seemed to be an uncommon phenomenon because no other reports or other descriptions were presented in the literature.…”

“…There are few studies concerning the presence of holocyclic aphids in tropical and subtropical regions, and only the occurrence of males and oviparous females of some species can be found in the literature from Brazil (Menezes 1970, Costa et al 1972, Cabbete 1995, Lazzarotto & Lazzari 2005, but no data on eggs has been recorded. For T. kahawaluokalani all morphs (parthenogenetic viviparous females, oviparous females, males and the winter eggs) were found on L. indica in southern Brazil, by the authors of this research.…”

Neotropical Entomology 35(6):762-768 (2006) ABSTRACT -This is the fi rst record of winter eggs of the holocyclic monoeceous crapemyrtle aphid Tinocallis kahawaluokalani (Kirkaldy) on Lagerstroemia indica L., in Brazil. The shiny black eggs were observed since early autumn, laid on small folds and crevices of the branches. In order to evaluate and model the egg abundance and distribution, four branches from the cardinal points of 10 plants of two age groups, 5-10 and 20-30 years-old, were collected randomly and cut in eight segments of 10 cm and the number of eggs was registered, in the winter 2001. The eggs were laid mainly on the middle portion of the branch, from 40 cm to 60 cm from the apex on the older trees (54%) and on 30 cm to 60 cm on younger ones (58%). The data fi t in a longitudinal regression model that expresses the tendency of the egg distribution on the branches. The number of eggs was greater on the 20-30 year-old plants (61%) than on younger ones (39%). The average number (± CI 95%) of eggs was 70.5 9.3 and 47.4 12.5, respectively, for the older and younger tree groups. There was no correlation between egg distribution and the cardinal positions of the branches.
