Ecdysteroids in the ovary and the egg of the greater wax moth

Journal of Insect Physiology, 1979
Abstract Galleria mellonella eggs exhibit a remarkably high molting hormone activity, equivalent to 74 μg/g fresh wt of ecdysone or ecdysterone. The activity in the ovary was also substantial, averaging 0.4 and 0.58 μg/female, respectively, in the pharate adults and in the 1-day-old adults. Seven ecdysteroids were isolated from the eggs.

Microbial toxin activity on larvae of the gypsy moth and greater wax moth

Zeitschrift für Angewandte Entomologie, 1978
AbstractThe activity of four mycotoxins extracted fromBeauveria bassiana, Paecilomyces fumosoroseusandNomuraearileyi and a bacterial exotoxin ofBacillus thuringiensisvar.thuringiensiswere assayed for activity on larvae of the greater wax moth and the gypsy moth.

Immunity of the greater wax mothGalleria mellonella

Insect Science, 2016
AbstractInvestigation of insect immune mechanisms provides important information concerning innate immunity, which in many aspects is conserved in animals. This is one of the reasons why insects serve as model organisms to study virulence mechanisms of human pathogens.

Biochemical Stress Indicators of Greater Wax Moth Exposure to Organophosphorus Insecticides

Journal of Economic Entomology, 2005
Although acetylcholinesterase (AChE) is the primary target of organophosphorus insecticides (OPs), increasing evidence regarding their secondary effects suggests that OPs disturb homeostasis of insects by generating free radical intermediates that trigger lipid peroxidation.

Simultaneous determination of molting and juvenile hormone titers of the greater wax moth

Journal of Insect Physiology, 1977
Abstract A simple and rapid extraction procedure was developed to determine simultaneously the molting hormone (MH) and juvenile hormone (JH) activity in a single insect tissue sample. From the onset of the last larval stage to adult eclosion of the greater wax moth, Galleria mellonella, three JH peaks were noted: at the time of the sixth larval ...

Apolipophorin‐III in the greater wax moth, Galleria mellonella (Lepidoptera: Pyralidae)

Archives of Insect Biochemistry and Physiology, 2001
AbstractThe level of apolipophorin‐III reached a maximum in the haemolymph of Galleria mellonella at the end of the feeding phase of the seventh larval instar and declined to a plateau value in the pupal and the adult stages. Apolipophorin‐III was detected immunologically in fat body tissue, haemocyte lysates, and plasma.

Partial-pupae of the greater wax moth, Galleria mellonella (Linnaeus)

Journal of Invertebrate Pathology, 1965
Abstract Under laboratory culture, individuals of the greater wax moth, Galleria mellonella (Linnaeus), are occasionally observed which only partially complete the larval-pupal transformation and then die. In form they appear as larvae, however, a large portion of the body is hard and dark and thereby appears pupal.

Neoaplectana parasitism of larvae of the greater wax moth, Galleria mellonella

Journal of Invertebrate Pathology, 1967
Abstract The infective stage of the neoaplectanid nematode DD-136 enters the alimentary tract of Galleria mellonella via the mouth. After exsheathing in the crop or midgut of the host, the third-stage juveniles penetrate through the wall of the midgut, apparently by mechanical means, and enter the hemocoel.

Studies on the mucopolysaccharides of the greater wax moth, Galleria mellonella (Linnaeus)

Comparative Biochemistry and Physiology, 1964
Abstract 1. 1. Procedures for the extraction of mucopolysaccharides from the midgut of the wax moth are presented. 2. 2. Chromatography of this extract on the anion exchanger, ECTEOLA cellulose, showed the presence of a single component, having a elution pattern similar to that of mammalian hyaluronic acid. 3. 3.

Evaluation of Insecticides To Control Honey Bees and The Greater Wax Moth

Insecticide and Acaricide Tests, 1977
Abstract Although the honey bee is a valuable pollinator and should be protected from pesticides, colonies must sometimes be destroyed because of infectious diseases. The greater wax moth causes considerable damage every year to stored combs.
