Compared with the larva of Birka cinereipes (Klug), which feeds on forget-me-nots (Myosotis scorpioides), it shows some apomorphic characters: fusion of four apical antennal segments and reduction of sixth dorsal annulet on the third abdominal segment. It is the first sawfly larva known to feed on mosses (Bryopsida). The cocoon has a special structure. The larvae of the tribe Aneugmenini have an extra moult after the feeding period and differ in that respect from

Abstract:
AbstractThe turnip sawfly, Athalia rosae Linnaeus, is a pest on cruciferous crops. Larvae sequester secondary plant compounds, namely glucosinolates, in their haemolymph. When attacked, their integument is easily disrupted and a droplet of haemolymph is exuded (‘easy bleeding’). This has been shown to be an effective, chemical-based, defence against invertebrate predators. The efficiency of this proposed defence was tested against a vertebrate predator, using groups of the iguanid lizard Anolis carolinensis Voigt as a model predator.

Abstract:
Sawfly larval poisoning (SLP) is an acute hepatotoxicosis documented in livestock in Australia, Denmark and in countries of South America. It is caused by the ingestion of the larval stage of insects of the suborder Symphyta, order Hymenoptera, commonly known as "sawfly". Three species of sawfly are reportedly involved in the toxicosis. The insect involved in Australian SLP is Lophyrotoma interrupta (Pergidae), in Denmark the cause of SLP is the ingestion of the larvae Arge pullata (Argidae), and in South American countries documented outbreaks of SLP were caused by the ingestion of yet anothe

Larval infections are characterized by hypertrophy of midgut epithelial cell nuclei, where virogenic stromata develop to produce nucleocapsids that are singly enveloped before occlusion into occlusion bodies. Infected, occlusion body-laden cells slough from the midgut epithelium as a result of a dissolution of the basal lamina. Infected cells undergo lysis, and viral

Abstract Host plant traits strongly affect survivorship of insect herbivores, and host suitability is especially important for the wheat stem sawfly, Cephus cinctus Norton, which spends its entire egg, larval, and pupal periods in a single stem. Measuring larval survival inside stems from egg hatch through diapause-mediated dormancy is a potential measure of population size for the next year but is also useful in assessing effects of growing season precipitation and temperature. Larval growth is synchronized with host plant growth, and the larva cannot switch hosts. Thus, incorporating plant p

Abstract:
Unsupervised learning-based action recognition methods have shown immense potential by leveraging vast amounts of unlabeled data, yielding competitive performance in action recognition tasks. To capture semantic information in action, many efforts have focused on multi-stream fusion techniques, which makes the models heavier and less flexible to train. However, existing single-stream methods struggle to provide rich semantic information through data augmentation. To address these challenges, we propose a novel joint-level semantic augmentation method based on a constructed motion manifold, whi

Abstract Understanding the actual effect of stress distribution within longitudinally submerged-arc welded (SAWL) large-diameter pipe is essential for reliable and practical execution of sulfide stress cracking (SSC) tests. To qualify SAWL pipe as SSC resistant, SSC tests are typically performed on four-point bend specimens pre-stressed to a certain level within the elastic regime. For a detailed evaluation of stresses present in pipe and in four-point bend specimens, subjected to typical loads with respect to AYS and SMYS, the local stress at the unmachined part of the inner weld was simulate

Large diameter UOE pipes are being increasingly used for the construction of offshore pipelines. Since oil discoveries are moving towards ultra-deepwater areas, such as Pre-Salt in Brazil, collapse resistance is a key factor in the design of the pipelines. It is known that the cold forming, and the final expansion in the UOE linepipe manufacturing process, reduces the elastic limit of the steel in subsequent compression. Due to this, the DNV collapse formula includes a fabrication factor that derates by a 15% the yield strength of UOE Pipes. However, DNV also recognizes the effect of thermal t
