Here, we show that an α-proteobacterium of the genus Asaia is stably associated with larvae and adults of Anopheles stephensi, an important mosquito vector of Plasmodium vivax, a main malaria agent…
Natural enemies of the South American moth, Tuta absoluta, in Europe, North Africa and Middle East, and their potential use in pest control strategies
Among the recovered indigenous natural enemies, only few parasitoid species, namely, some eulophid and braconid wasps, and especially mirid predators, have promising potential to be included in effective and environmentally friendly management strategies for the pest in the newly invaded areas.
Rearing, release and settlement prospect in Italy of Torymus sinensis, the biological control agent of the chestnut gall wasp Dryocosmus kuriphilus
There are encouraging data about the settlement of the parasitoid and its synchrony with the host’s cycle: from about 64,000 host galls collected in the field over 200 T. sinensis were reared and the role of native parasitoids associated with the chestnut gall pest in its Italian distribution range is also discussed.
Asaia, a versatile acetic acid bacterial symbiont, capable of cross-colonizing insects of phylogenetically distant genera and orders.

The ability in cross-colonizing insects of phylogenetically distant orders indicated that Asaia adopts body invasion mechanisms independent from host-specific biological characteristics, an important property for the development of symbiont-based control of different vector-borne diseases.

The demonstration of multiple modes of transmission between individuals and to their progeny that include vertical and horizontal transmission routes, comprising a venereal one, indicate that AAB represent novel secondary symbionts of insects.

Preliminary results demonstrated a high suitability of these indigenous natural enemies for controlling T. absoluta in controlled conditions and their role as potential biological agents in commercial tomato plantations.
POPULATION DYNAMICS, HOST PLANTS AND INFECTION RATE WITH STOLBUR PHYTOPLASMA OF HYALESTHES OBSOLETUS SIGNORET IN NORTH-WESTERN ITALY
Results confirm the strong links between H. obsoletus, Bois Noir, and U. dioica in northwestern Italy and the life span of the planthopper was observed on nettle whereas broadbean and grapevine were not suitable for survival.
Acetobacter tropicalis Is a Major Symbiont of the Olive Fruit Fly (Bactrocera oleae)

- 20 March 2009
This acetic acid bacterium was successfully established in cell-free medium, and typing analyses, carried out on a collection of isolates, revealed that different A. tropicalis strains are present in fly populations.
Multiple symbiosis in the leafhopper Scaphoideus titanus (Hemiptera: Cicadellidae): details of transovarial transmission of Cardinium sp. and yeast-like endosymbionts.
Population Dynamics of Cacopsylla melanoneura (Homoptera: Psyllidae), a Vector of Apple Proliferation Phytoplasma in Northwestern Italy
Investigations in northwestern Italy to identify the vector of apple proliferation and to study its population dynamics confirmed the presence of the apple proliferation phytoplasmas in both overwintering and offspring insects as well as in symptomatic apple plants.
