Insecticidal 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 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...
متن کاملA cadherin-like protein influences Bacillus thuringiensis Cry1Ab toxicity in the oriental armyworm, Mythimna separata.
Cadherins comprise a family of calcium-dependent cell adhesion proteins that act in cell-cell interactions. Cadherin-like proteins (CADs) in midguts of some insects act as receptors that bind some of the toxins produced by the Bacillus thuringiensis (Bt). We cloned a CAD gene associated with larval midguts prepared from Mythimna separata. The full-length cDNA (MsCAD1, GenBank Accession No. JF95...
متن کاملBehavioral evidence for a magnetic sense in the oriental armyworm, Mythimna separata
Progress has been made in understanding the mechanisms underlying directional navigation in migratory insects, yet the magnetic compass involved has not been fully elucidated. Here we developed a flight simulation system to study the flight directionality of the migratory armyworm Mythimna separata in response to magnetic fields. Armyworm moths were exposed to either a 500 nT extreme weak magne...
متن کاملEffects of Periplocoside P from Periploca sepium on the Midgut Transmembrane Potential of Mythimna separata Larvae
Periplocoside P (PSP) isolated from the root bark of Periploca sepium contains a pregnane glycoside skeleton and possesses high insecticidal properties. Preliminary studies indicated that PSP disrupts epithelial functions in the midgut of lepidopteran larvae. In the present study, we examined the effects of PSP on the apical and basolateral membrane voltages, Va and Vbl, respectively, of cells ...
