Molecular profiling of nematode associates with in southern Italy.

A survey of nematodes associated with the red palm weevil was conducted in southern Italy in 2015 and 2016 in order to create a species inventory and obtain data about nematode biodiversity. A total of 70 insect samples (pupae and adults) were collected from infested , , and palms in three Italian Regions: sampling took place at 11 locations in Apulia, 1 in Basilicata, and 1 in Sardinia regions. Individual insects were dissected to determine nematode presence, and different nematode species were also recovered from red palm weevil cocoons collected at the sites in Apulia.

Integrative diagnosis, biological observations, and histopathology of the fig cyst nematode Kirjanova (1954) associated with L. in southern Italy.

Morpho-biological notes and histopathology, based on LM and SEM observations, of the fig cyst nematode isolated from roots, collected in home and public gardens of Apulia region, southern Italy, are described and illustrated. Seventy-five localities throughout the Apulia region were sampled and one-quarter of the sampled localities had fig roots infested with , with population densities ranging from 44 to 180 cysts/100 ml of soil. All attempts to detect on ornamental spp.

Pathogenicity and Host-Parasite Relationships of Heterodera cruciferae in Cabbage.

Stunted cabbage ('Lupini') associated with severe soil infestations by a cyst-forming nematode were observed in large patches of open fields in Castellaneta, province of Taranto, southern Italy. Morphological traits based on mature cysts, males, and second-stage juveniles (J2s) and molecular analysis of ribosomal DNA (D2 to D3 expansion segments of 28S and internal transcribed spacer [ITS]1 region) were used to identify the species. ITS1 sequence information supported the identity of Heterodera cruciferae, also showing a high degree of similarity to other species of the Heterodera Goettingiana group, including H.
