Complementarity of statistical treatments to reconstruct worldwide routes of invasion: the case of the Asian ladybird Harmonia axyridis
This study provides biologists without expertise in this area with detailed methodological and conceptual guidelines for making inferences about invasion routes when dealing with a large number of sampling sites and complex population genetic structures.
Inert dusts and their effects on the poultry red mite (Dermanyssus gallinae)
A tarsal test showed that 24 h exposure to surfaces treated with doses much lower than those recommended by the producers is sufficient to kill mites as fast as when they were dusted with massive doses, emphasising the need for thorough treatment of all surfaces in a poultry house in order to combat D. gallinae.

A 2-year study of the natural occurrence of entomopathogenic fungi in adult cattle flies and other flies associated with pastures showed that the four species included in the Entomophthora muscae species complex caused high infection levels in several species of flies.
Entomopathogenic fungi associated with Ixodes ricinus ticks
Entomopathogenic fungi may have a significant impact on the size of the I. ricinus population, since females were the most frequently infected stage and throughout the season, a significantly higher proportion of ticks collected in autumn were infected.

Regardless of the MdSGHV isolate tested, all susceptible insects displayed similar degrees of SGH and complete suppression of oogenesis; however, 24-h-old flies displayed a resistance to oral infection that was significantly greater than that displayed by newly eclosed adults.
Living with the enemy: parasites and pathogens of the ladybird Harmonia axyridis
An overview of the parasites and pathogens of coccinellids with a particular focus on H. axyridis as a host is provided and it is predicted that H.Axyridis could benefit from both enemy release and EICA within the introduced range but require further empirical evidence.

Insecticidal effect of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreaes) in combination with three diatomaceous earth formulations against Sitophilus granarius (L.) (Coleoptera:…
Parasites of Harmonia axyridis: current research and perspectives
This study presents a review of the parasites of H. axyridis, discussing their distributions and effects on host populations across the host’s native and invasive range.
Effect of Metarhizium anisopliae (Deuteromycotina: Hyphomycetes) on Survival and Reproduction of the Filth Fly Parasitoid, Spalangia cameroni (Hymenoptera: Pteromalidae)
The susceptibility of the parasitoids to fungal infection had no discernible effect on the intrinsic rate of natural increase (rm), which strongly suggests that the isolate of M. anisopliae and S. cameroni could be compatible under field conditions.
