Abstract Unintentional introduction of natural enemies has increased in recent years due to a massive rise global trade and tourism. One such enemy is the Asian egg parasitoid Trissolcus japonicus , promising agent for classical biological control Halyomorpha halys. In Europe, adventive T. populations have been detected Switzerland, Italy Germany. Host specificity testing demonstrated that its ...

Many studies have investigated how social insects behave when a parasite is introduced into their colonies. These studies have been conducted in the laboratory, and we still have a limited understanding of the dynamics of ant-parasite interactions under natural conditions. Here we consider a specialized parasite of ant societies (Ophiocordyceps camponoti-rufipedis infecting Camponotus rufipes) ...

Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese-Tullgren funnels. Necrophagous fauna on t...

A study was conducted to compare the species of adult ixodid ticks on Friesian and Bonsmara cattle and their seasonal dynamics. Between five and ten animals of each breed were kept on natural False Upper Karoo vegetation, typical of the south-western Free State. Between May 1990 and October 1991, the animals were examined once or twice a month for the presence of adult ticks which were removed,...

This paper is aimed to summarize the information available on the parasitoid complex of the European Grapevine Moth (EGVM), Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera Tortricidae) in Italy. The list is the result of the consultation of a vast bibliography published in Italy for almost two hundred years, from 1828 to date. This allowed the clarification and correction of misunde...

Many omnivorous arthropods act as important pest control agents in agroecosystems. Assessing their prey choices helps to better understand biocontrol potential different environmental settings. To this end, multi-target approaches of molecular gut content analysis allow studying choices. Yet, DNA-based trophic interactions is challenged by the question whether detected food DNA was ingested pri...

Heilipus gibbus sp. nov. (type locality: Brazil, state of São Paulo, Angatuba) is described from 73 specimens. The holotype and three paratypes from the same locality were reared from larvae collected in the basis region, near the ground, of an atemoya tree (a hybrid of the sugar-apple, "pinha" or fruta-do-conde"-Annona squamosa L., and the cherymoya, A. cherimoya (Mill.), Annonaceae). Heilipus...

Many studies on the population dynamics of questing ticks on pastures and of parasitic ticks on cattle have been conducted. Few, however, have attempted to link the two in a single study. This study aimed to assess the population dynamics of questing ixodid ticks on pastures and of adult ticks on two breeds of cattle with different levels of susceptibility to tick infestation on the same pastur...
