The role of chemical cues in the host finding behaviour of Trissolcus basalis from a Conservation Biological Control perspective

In assessing successful biological control programs by parasitoids, the knowledge of important traits, such as the host finding capability, i.e. the ability to find host and food resources, play the key role. Moreover, parasitoids in their natural environment parasitoids deal with a variable mixtures of natural cues. Some chemical cues are used by the wasps to locate their hosts, some ones drive wasps to feeding resources. The parasitoid response to these cues can fluctuate according to biotic factors and abiotic condition. This dissertation focus in details on the role of two important tools, such as selective flowering plants as food resources to add within a crop area and the traces left…

Wildflowers: opportunities for urban landscapes

2022

The concept of “sustainability” is also becoming of great interest in the management of ornamental and territorial greenery. The new trends in the design of green spaces are aimed both at enhancing their “natural” aspects and at researching schemes characterized by lower maintenance costs. Spontaneous vegetation represents a characteristic component of the urban environment and is always adequate to the conditions of the site in which it is located. In this context, the role of spontaneous herbaceous plants becomes fundamental and constitutes an effective response to the current demand for the defence, conservation and enhancement of biodiversity. So far, the use of spontaneous vegetation f…
