Proboscis structure and sensilla types are important morphological characters for the systematic analysis of Lepidoptera families. There is no study on proboscis Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae) despite fact that it an pest. For this purpose, A. were investigated by using stereomicroscope scanning electron microscope in detail. The results show has three sensillum (sensi...

We report on the ultrasound (US) detection of holoprosencephaly with cyclopia at a gestational age of 16 weeks. The sonographic diagnosis was based on the intracranial finding of fused thalami with no visible midline structures and facial abnormalities, including cyclopia and proboscis. We evaluated the fetal face by 3-dimensional (3D) transabdominal US and were able to identify the cyclopia be...

For an animal to survive in a constantly changing environment, its behavior must be shaped by the complex milieu of sensory stimuli it detects, its previous experience, and its internal state. Although taste behaviors in the fly are relatively simple, with sugars eliciting acceptance behavior and bitter compounds avoidance, these behaviors are also plastic and are modified by intrinsic and extr...

This study describes proboscis morphology and identifies morphometric differences among five species of noctuid moths with different feeding habits (fruit versus nectar-feeding). Morphological and morphometric parameters were analyzed using scanning electron microscopy and light microscopy. Measurements included: galea height in ten sites from base to tip, total proboscis length, and length of ...

Aplasia of the nose is a very rare, congenital anomaly in our field. It emerges as a complete absence of the external nose and all nasal cavities on both sides, or an absence of one half of the nose and its associated nasal cavity. The latter case is called "halfnose." Etiologically, it is akin to tubular proboscis, anomaly with a snout-like nasal appendage on, or by the mid-line of the face. T...

Morphological variants showing differences in length of median white scaled bands on the proboscises of female Aedes sollicitans (Cape May County, NJ) are described from F1 progeny of wild-caught mosquitoes. The length of the white-scaled band was classified into 5 categories: 1) large (0.53-0.60 mm), 2) medium (0.40-.47 mm), 3) small (0.27-0.33 mm), 4) very small (0.13-0.20 mm) band to a patch...

The ability of Lepidoptera, or butterflies and moths, to drink liquids from rotting fruit and wet soil, as well as nectar from floral tubes, raises the question of whether the conventional view of the proboscis as a drinking straw can account for the withdrawal of fluids from porous substrates or of films and droplets from floral tubes. We discovered that the proboscis promotes capillary pull o...

Hematophagous leeches express a broad variety of secretory factors in their salivary glands; among them are hirudins, inhibitors blood coagulation, and decorsins/ornatins, platelet aggregation. Here, we describe the identification molecular functional characterization putative hirudins decorsins/ornatins two leech species American origin, Limnobdella mexicana Haementeria vizottoi. The represent...
