Exotic ambrosia beetles are emerging widespread pests of several wild and managed trees shrubs. Xylosandrus compactus (Eichhoff) is one the most invasive species causing damage to a broad range host plants. Little information available on its control, including impact insecticides. Bioassays were conducted evaluate potential four bioinsecticides seven synthetic insecticides in controlling X. compactus. Beetle mortality sublethal effects tunneling, cultivation mutualist fungus reproduction assessed.Concentration-mortality curves determined for all tested Lambda-cyhalothrin was toxic insecticide, showing lowest estimated 90% 50% lethal concentrations (LC90 LC50 ), followed by deltamethrin thiamethoxam. Acetamiprid caused highest levels brood size reduction under extended laboratory conditions. Moreover, acetamiprid, thiamethoxam lambda-cyhalothrin greatest and, together with deltamethrin, strongly affected progeny occurrence inside infested galleries beetle size. Among bioinsecticides, pyrethrins significantly survival conditions, but not bioassays. Some had significant only when exposed fresher residues, highlighting differences toxicity persistence.This study provides first baseline data different modes action origin toward compactus, evidence that can cause multiple this pest.

The Western conifer seed bug, Leptoglossus occidentalis, is native to North America and has already been considered a significant pest in several European countries since its first observation Italy 1999. In Spain Portugal, it was recorded for the time 2003 2010, respectively, impact on Stone Pine (Pinus pinea) of major concern. Before developing control measures this insect pest, paramount clarify spatiotemporal dynamics invasion. Therefore, study, we aimed (a) characterise genetic structure diversity (b) invasion pathways L. occidentalis populations Iberian Peninsula. To do so, specimens were collected at fourteen sites widely distributed within We used mtDNA sequences Cytochrome b eleven microsatellite markers population Our results combined with observational dates strongly support stratified expansion Peninsula proceeding from multiple introductions, including least one Barcelona, Valencia, west coast or Southeastern region.
