Resistance monitoring and assessment of resistance risk to pymetrozine in Laodelphax striatellus (Hemiptera: Delphacidae).
J. Econ. Entomol. 105(6) , 2129-35, (2012) Laodelphax striatellus (Fallén) is a major pest of cultivated rice. Pymetrozine, a pyridine azomethine compound, represents a novel insecticide with a selective activity against sucking pests. The resistance of L. striatellus to thiamethoxam, nitenpyram, chlo... |

Locusts as model organisms in which to study immunogen-induced anorectic behaviour.
J. Insect Physiol. 56(8) , 991-7, (2010) When injected into adult or nymphal Locusta that have been deprived of food for 2h, immunogens such as laminarin and bacterial LPS can induce an almost immediate dose-dependent state of anorexia for at least 1h. Such anorexia is a component of a medley of phy... |

The effect of pymetrozine (Plenum WG-50) on proboscis extension conditioning in honey bees (Apis mellifera: Hybrid var. Buckfast).
Ecotoxicol. Environ. Saf. 78 , 287-95, (2012) Experiments are designed to examine the effects of pymetrozine (Plenum WG-50), a recent systemic pesticide of the pyridine-azomethin family, on Pavlovian conditioning of harnessed foragers. In one set of experiments bees learned a task in which they associate... |

Pymetrozine causes a nontarget pest, the Colorado potato beetle (Coleoptera: Chrysomelidae), to leave potato plants.
J. Econ. Entomol. 101(1) , 74-80, (2008) Pymetrozine is a selective insecticide that targets aphids. Published assessments of the effects of pymetrozine on nontarget organisms focus mainly on predatory insects, and they rarely indicate toxicity. In a laboratory bioassay, survival of Colorado potato ... |

Experimental and DFT studies on the vibrational and electronic spectra of 4,5-dihydro-6-methyl-4-[(E)-(3-pyridinylmethylene)amino]-1,2,4-triazin-3(2H)-one.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 83(1) , 112-9, (2011) Vibrational and electronic spectral measurements were made for 4,5-dihydro-6-methyl-4-[(E)-(3-pyridinylmethylene)amino]-1,2,4-triazin-3(2H)-one (pymetrozine). Optimized geometrical structure and harmonic vibrational frequencies were computed by ab initio RHF,... |
