Studies on Synthetic Pyrethroid

Bulletin of the Agricultural Chemical Society of Japan, 1957
Methyl αδ-dimethylsorbate, when submitted to the selective oxidation sequence by the actions of perbenzoic acid, mineral acid, lead tetraacetate and peracetic acid in this order, finally gives β-monomethyl mesaconate, which is converted after hydrolysis to mesaconic acid of the well-defined trans-configuration. The reaction sequence involves no process

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

Journal of Applied Entomology, EarlyView.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

Journal of Applied Entomology, EarlyView.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.
