“…Such finding was also previously reported for morphological studies with others species like Triatoma dimidiata (Heteroptera: Reduviidae) (Lehmann et al 2005), Podisus mucronatus (Heteroptera: Pentatomidae) (Costello et al 2002), Oxelytrum discicolle (Coleoptera: Silphidae) (Ferreira et al 2006), Oncideres dejeani (Coleoptera: Cerambycidae) (Seffrin et al 2006 Males of P. decempunctatus showed only two body traits larger than the females: antennal length and 2 nd antennal segment length. Males usually have larger antennae than females because they have more sensory sensilla related to their increased capacity of locating females for mating (Chapman 1998).…”

The analysis with 27 morphological traits was carried out to verify the seasonal influence, differences between sexes and among populations in specimens from Viçosa. The females of P. decempunctatus collected in Viçosa were larger than the males in most of the traits evaluated in both seasons (dry and wet). The males showed only two body traits larger than the females. Interpopulational morphometry differences of P. decempunctatus were significantly correlated with geographic distance among sampling sites. Resumo: Foi realizado um estudo morfométrico com Platyscytus decempunctatus (Carvalho 1945) coletados durante as estações seca e úmida no município de Viçosa, MG e em 23 municípios distribuídos pelos estados de Minas Gerais e Rio de Janeiro. Foram utilizados 30 machos e 30 fêmeas por estação no estudo de Viçosa e insetos adicionais (20 machos e 20 fêmeas) de cada um dos 23 municípios amostrados. Foram analisadas 27 características morfológicas a fim de verificar a influência sazonal e diferenças no dimorfismo sexual em indivíduos de Viçosa e diferenças entre as populações amostradas. As fêmeas de P. decempunctatus coletadas em Viçosa foram maiores que os machos na maioria das características avaliadas em ambas as estação (seca e úmida). Os machos apresentaram somente duas características corporais maiores que as fêmeas. Diferenças morfométricas interpopulacionais em P. decempunctatus se correlacionaram à distância geográfica entre os locais de coleta.

“…Assessing the morphometric characteristics of insects has been very useful in population studies, in terms of communities, and is used for the identification of nymph stages, features of sexual dimorphism (Zolessi, 1956;Turk and Barrera, 1976;Cepeda-Pizarro et al, 2003;Domenico, 2005;Cherril, 2005;Franceschini et al, 2005;Ferreira et al, 2006;Seffrin et al, 2006), life history and evolution with host plants (Klingenberg and Spence, 1997;Ahnesjö and Forsman, 2003;Adis et al, 2008), as well as ecological studies of populations and communities (Dirsh, 1953;Roonwal, 1981;Filin and Ovadia 2007;Pires et al, 2008).…”

Insects show morphometric variations associated with the environment that may be the result of phenotypic response or genetic inheritance, or both. Thereby, studies that emphasise the variability in body size are very useful for understanding the dynamics and the stability of ecological systems. Cornops aquaticum (Bruner, 1906) (Acrididae) is a semi-aquatic grasshopper, distributed from the southeast of Mexico to the south of Buenos Aires Province, Argentina, and is intimately associated with the aquatic macrophytes Eichhornia spp. and Pontederia spp. In its wide habitat distribution, C. aquaticum shows variations in its life cycle and morphometric differences that were observed suggesting geographic and host plant influence. Considering these findings, this study aimed to find out the morphometric characteristics of this species at the Pantanal of Poconé -MT, using the protocol of the project "HICWA -Host-Insect Coevolution on Waterhyacinth", as well as to assess possible differences in each stage of development between the sexes and among seasonal periods (flood, high water, low water and dry). During 12 months a total of 600 individuals were collected in monthly collections of 50 grasshoppers, and of this total, 261 were adults and 339 nymphs. The following measurements were taken: total length (A); body length (B); wing length (I) and measurement of the hind femur (H). The results showed that both male and female have different measurements but not correlated with seasonal periods. The average obtained for each character and the seasonality showed the highest values during the flood period. In nymphs, the measurement of the posterior femur presented the lower variation between individuals and characters.Keywords: body size, development, grasshopper, sexual dimorphism, Pantanal.

“…Oncideres impluviata, embora seja a principal praga da acácia negra também infesta outras plantas hospedeiras pertencentes às famílias Mimosaceae, Caesalpiniacea e Aquifoliaceae, com relatos de ocorrência em diversos estados brasileiros, além de outros países, como Paraguai, Argentina e Uruguai. Porém, a concentração da praga ocorre principalmente no estado do Rio Grande do Sul (BAUCKE, 1958;AMANTE et al, 1976;GALILEO, MARTINS, 2006;SEFFRIN et al, 2006), provavelmente em decorrência da grande área de plantio de acácia negra (ONO; FERREIRA; GODOY,…”
