Abstract:
... Morphological analyses of the internal anatomy are a milestone in different fields of animal biology, such as physiology, development and reproduction, and systematic studies. Synchrotron radiation X-ray phase-contrast microtomography (SR-PhC micro-CT) has become a valuable imaging tool used for non-invasive analyses of the insect internal anatomy. The ground beetle Pterostichus melas italicus Dej ...

Subject:
Nymphalidae; butterflies; color; fractal dimensions; insect morphology; morphogenesis; pigmentation; wings
Abstract:
... The nymphalid groundplan is an archetypical color pattern of nymphalid butterflies involving three major symmetry systems and a discal symmetry system, which share the basic morphogenesis unit. Here, the morphological and spatial relationships among these symmetry systems were studied based on cross-species comparisons of nymphalid hindwings. Based on findings in Neope and Symbrenthia, all three m ...

Abstract:
... Cuticular proteins (CPs) are known to play important roles in insect development and defence responses. The loss of CP genes can lead to changes in insect morphology and sensitivity to the external environment. In this study, we identified the AccCPR2 gene, which belongs to the CPR family (including the R&R consensus motif) of CPs, and explored its function in the response of Apis cerana cerana to ...

Abstract:
... Geometric morphometrics has become an important approach in insect morphology studies because it capitalizes on advanced quantitative methods to analyze shape. Shape could be digitized as a set of landmarks from specimen images. However, the existing tools mostly require manual landmark digitization, and previous works on automatic landmark detection methods do not focus on implementation for end- ...

The species Helicoverpa armigera (Hübner) was responsible for significant yield losses in several crops after its detection in Brazil. The morphology of its larval stage resembles common Heliothinae species, making pest control decisions difficult. The overall lack o ...
