The Restinga Antwren (Formicivora littoralis) has a narrow distribution range in southeastern Brazil, and it is a typical species of restinga habitat (sandy coastal plain vegetation). In this paper, we describe two new records for the species (22 degrees 51' 45" S and 42 degrees 14' 13" W; 22 degrees 51' 14" S and 42 degrees 11' 47" W) in the northern margin of the Araruama Lagoon, which repres...

Food, mates and host plants are essential resources for plant-feeding insects. Optimal resource localization that fulfils the physiological need and reproductive goals of an insect is of utmost importance. Insects, like most animals, rely largely on the sense of smell to locate and evaluate potential resources that enhance their reproductive fitness. Confronted with a multitude of stimuli rangi...

The great phenotypic variability and the lack of diagnostic characters in the genus Pylaiella render the systematic study of this genus problematic. In this study, we investigated the diversity of Pylaiella littoralis along the Brittany (France) coast using a DNA barcoding multilocus approach with mitochondrial (cox1, nad1, and atp9) and chloroplastic (rbcL and atpB) markers associated with a p...

primary information about different methods of vegetation sampling is important to researchers to decide about their sampling. in this study we applied five distance methods (closest individual, nearest neighbor, random pairs, point-centered quarter and angle orderd) to estimate plant density in three vegetation types including artemisia sieberi, juncus littoralis and punica granatum in mazanda...

The aim of this study was to determine the insecticide potential essential oils (EOs) thyme (Thymus vulgaris; Lamiaceae) and ginger (Zingiber officinale; Zingiberaceae) control cotton leaf worm (Spodoptera littoralis; Lepidoptera: Noctuidae) under laboratory conditions. Generally, there a positive correlation between magnitude above toxic effects concentrations all EOs. Ginger oil (GEO) showed ...

Odorant-binding proteins were studied in the noctuid moths Agrotis segetum, Autographa gamma, Helicoverpa armigera, Heliothis virescens and Spodoptera littoralis using antisera raised against the pheromone-binding protein (PBP) and general odorant-binding protein 2 (GOBP2) of Antheraea polyphemus (Saturniidae). Proteins immunoreacting with these antisera were only found on the antennae and PBP ...

In Fig. 2b of this Article, the distribution map for Necrodes littoralis was inadvertently duplicated under the label Necrophila brunnicollis. The correct version of Fig. 2 appears below.

Studies on the effect of different host-plants on the development and fecundity of the cotton leafworm S. littoralis were carried out under constant laboratory

Animals depend on reliable sensory information for accurate behavioural decisions. For herbivorous insects it is crucial to find host plants for feeding and reproduction, and these insects must be able to differentiate suitable from unsuitable plants. Volatiles are important cues for insect herbivores to assess host plant quality. It has previously been shown that female moths of the Egyptian c...
