Kinematic Feature for Classifying Larvae: Aedes Larvae and Culex Larvae [PDF]

open access: possible2020 International Electronics Symposium (IES), 2020
This paper deals with Larvae detection. There are 2 larvae in a similar genre, physically similar, but one larva (Aedes) is a vector of dangerous dengue fever, while Culex is not. Kinematic feature: velocity and acceleration, are employed to distinguish them. Video data of 120 samples are analyzed.

In Vitro Antibacterial Activity of Black Soldier Fly (Hermetia Illucens) Larva Extracts Against Gram-Negative Bacteria

Buletin Peternakan, 2019
The aim of this study was to evaluate the in vitro antibacterial activity of Black soldier fly (BSF) larva extract. The BSF larva was extracted using methanol and then tested for antibacterial activity using agar diffusion method (zone growth inhibition).

Larva Migrans then

The American Journal of Tropical Medicine and Hygiene, 1989
Paul Beaver, in the first major review paper he wrote on larva migrans in 1956, made reference to a quote by that eminent biologist-parasitologist Arthur Looss in 1911 which perhaps has summarized the basic philosophy of Dr. Beaver in his approach to parasite research in general over the past 6 decades: “What I wish here to emphasize is that a correct ...

The antennae of damselfly larvae

Arthropod Structure & Development, 2018
The larval antennal sensilla of two Zygoptera species, Calopteryx haemorroidalis (Calopterygidae) and Ischnura elegans (Coenagrionidae) are investigated with SEM and TEM. These two species have different antennae (geniculate, setaceous) and live in different environments (lotic, lentic waters).

Larva-Specific Antibodies in Patients with Visceral Larva Migrans

Journal of Infectious Diseases, 1977
Seven of 10 patients with visceral larva migrans (VLM) had serum precipitating antibodies specific for larval antigens of Toxocara canis as determined by double diffusion in agar. Such antibodies were absent in 114 normal adults and 25 patients with collagen disease.

A miniaturized beetle larva in Cretaceous Burmese amber: reinterpretation of a fossil “strepsipteran triungulin”

, 2016
A wingless and eyeless tiny fossil embedded in Cretaceous amber from Myanmar is described and interpreted phylogenetically as beetle larva, very likely belonging to a cucujiform group of Coleoptera with parasitic habits, probably the family Ripiphoridae.

Pengaruh Jenis Limbah dan Rasio Umpan pada Biokonversi Limbah Domestik Menggunakan Larva Black Soldier Fly (Hermetia illucens)

, 2016
The high content of protein is the main reason for domestic waste to be potentially processed by bioconversion using Hermetia illucens larvae. Hermetia illucens larva can accumulate protein content as high as 45-50% and fat which reaches 24-30 %, so that

Larva on a string

Ophelia, 2002
Abstract Many types of suspension-feeding plankton larvae produce one or more, up to 1 cm long mucous strings. These function as drift anchors by increasing hydrodynamic drag. This effect, together with gravitational forces, allows the larvae to remain almost motionless relative to the undisturbed water column while feeding. Larvae that are essentially

SWIMMING AND FEEDING IN CRUSTACEAN LARVAE: THE NAUPLIUS LARVA

Proceedings of the Zoological Society of London, 1959
SUMMARYAn account is given of swimming and feeding in the nauplii of Artemia, Balanus, Calanus and Oithona, with observations on other nauplii. Previous work is reviewed.In all cases the antennae are the principal locomotion organs. The antennules may play little or no part in locomotion and are mainly balancing organs.In Artemia the antennae are also ...

Jasmonate in Lepidopteran Larvae

Journal of Chemical Ecology, 2006
Jasmonic acid (JA) is a key molecule initiating plant defensive responses to herbivory. Our previous work has shown that this phytohormone is often present at high concentrations in eggs and neonates of lepidopteran species. In this work, we document the concentrations of JA found in various tissues of larval H.
