Altered Immunity in Crowded Locust Reduced Fungal (Metarhizium anisopliae) Pathogenesis
The stress of living conditions, similar to infections, alters animal immunity. High population density is empirically considered to induce prophylactic immunity to reduce the infection risk, which was challenged by a model of low connectivity between infectious and susceptible individuals in crowded animals. The migratory locust, which exhibits polyphenism through gregarious and solitary phase...
متن کاملDopamine- induced hypophagia is mediated via NMDA and mGlu1 receptors in chicken
Background: Feeding behavior is regulated by a complex network which interacts via diverse signals from central and peripheral tissues. It is known dopaminergic and glutamatergic systems have crucial role on food intake regulation but scarce reports exist on their interaction in appetite regulation in broilers. OBJECTIVES: The present study was designed to examine the role of glutamatergic syst...
متن کاملInsecticidal compounds from Tripterygium wilfordii active against Mythimna separata.
In the course of screening for novel naturally occurring insecticides from plants, the ethanol extract of the root bark of Tripterygium wilfordii Hook f. was found to show insecticidal activity against larvae of Mythimna separata Walker. Three active compounds were isolated by bioassay-guided fractionation of the extract and characterized as triptolide (1), triptonide (2) and euonine (3) by IR,...
متن کاملBiocontrol of the oriental armyworm, Mythimna separata, by the tachinid fly Exorista civilis is synergized by Cry1Ab protoxin
Tritrophic interactions between Mythimna separata, its tachinid parasite Exorista civilis and the Cry1Ab were examined. Although 6th instar M. separata mortality increased with increasing Cry1Ab concentration, some tolerance was evident. Likewise, parasitization by E. civilis resulted in only 18% host mortality. However, combination of Cry1Ab and E. civilis parasitization resulted in a signific...
متن کاملCentral Projections of Antennal and Labial Palp Sensory Neurons in the Migratory Armyworm Mythimna separata
The oriental armyworm, Mythimna separata (Walker), is a polyphagous, migratory pest relying on olfactory cues to find mates, locate nectar, and guide long-distance flight behavior. In the present study, a combination of neuroanatomical techniques were utilized on this species, including backfills, confocal microscopy, and three-dimensional reconstructions, to trace the central projections of se...
