    Observations on midgut of Apis mellifera workers (Hymenoptera: Apoidea) under controlled acute exposures to a Bacillus thuringiensis-based biopesticide

    International audienceAbstractMorphostructural investigations have been carried out on Apis mellifera workers treated with single controlled acute exposures to a biopesticide containing Bacillus thuringiensis (Bt), to detect midgut changes until 96 h. Our findings show concentration-dependence of these changes, reflecting in different degrees on both mortality and behaviour. In particular, some midgut changes are also found 96 h after treatment. Our results show that the tested product does not affect survival at presumable environmental concentrations, so confirming the lesser toxicity of Bt-based biopesticides compared to other pesticides. However, in the light of the discovered long-term changes, we discuss the opportunity of taking into account possible chronic exposures to Bt-based products on A. mellifera

    Risk of introduction and establishment of exotic plant pathogens and insects harmful to Mediterranean plant biodiversity

    Get PDF
    Introduction of an exotic pathogen or insect in a region may not guarantee its establishment. The rapid evolution of climatic changes coupled with an increase in trade over the last ten years has resulted in a predictable but underestimated increase in introduction of plant and animal parasites in many regions of the Mediterranean basin. In addition to the damage to plant crops, the threat to wild biodiversity is also significant.peer-reviewe

    New records of Auchenorrhyncha (Hemiptera) from the Maltese Islands

    Get PDF
    The faunistic knowledge of the Auchenorrhyncha of the Maltese Islands is still incomplete. Studies on this insect group from the Maltese Islands were mostly neglected and it was only in recent years that some collecting efforts were carried out resulting in a published check-list of 46 species.peer-reviewe
