It's all about bugs.

Research instilled in me a passion for exploration and Science. I believe that Science is FUN and that the scientific method can be applied to our daily lives. My research interests are connected to insects, how they behave, how they interact with plants and how we can find a way to protect crops from them. Only 1-3 % of all insect species (more than 1 million described) are considered pests. As part of my studies and work experience, I worked for developing technologies to lower insect pest population levels below economic thresholds.

My research falls under the fields of Agriculture and Environment Science with a focus on Applied Entomology. I have experience in developing cold storage technologies for use in insect mass rearing programs, in-vitro rearing techniques for entomophagous insects, and quality control protocols. I am interested in developing innovative control strategies that are environmentally friendly, especially through the use of Integrated Pest Management. I enjoy working on spatial ecology of insect pests and developing in-field monitoring systems.

One of my favourites quotes: "Although man's sway is dominant in all parts of the Earth, there is considerable evidence that insects are the most characteristic form of life of the present age".

Research topics

Biological Control


I worked in both classical and augmentative Biological Control programs. I participated into a campaign against the exotic Chinese gall wasp (Dryocosmus kuriphilus) that encompassed field releases of the parasitoid Torymus sinensis, introduced in Italy from East Asia. I also investigated the effectiveness of the multicolored Asian ladybug (Harmonia axyridis) in controlling aphid populations in open fields and greenhouses while, at the same time, studying the causes of its invasiveness, including thermal biology, intraguild competition with native coccinellid species and insecticide resistance. For many years, I worked with tachinid flies (Exorista larvarum) as biological control agents of lepidopterans defoliators. I verified host acceptance and suitability to establish possible new associations with accidentally introduced pests.

Insect Mass Rearing


The pest management industry is increasingly demanding efficient mass rearing techniques that provide high-quality and cost-effective insect productions for use in Integrated Pest Management (IPM) programs. As part of Industry-funded research, I worked to develop artificial diets for the rearing of predators and artificial media for the rearing of endoparasitoids (in-vitro rearing) without using host components. We successfully developed a pork liver diet for the rearing of aphidophagous ladybugs, a skimmed milk and chicken egg yolk based media for the raring of tachinid flies out of host and an artificial diet for the rearing of the greater wax moth (Galleria mellonella). I also developed efficient cold storage technologies, for delaying insect development with minimal impacts on quality, for biological contol agents and fruit flies (Bactrocera tryoni).

Sterile Insect Technique (SIT)


The environmentally sustainable SIT is being applied worldwide against several major insect pests, including screwworms, fruit flies, moths and mosquitoes. With SIT, massive numbers of high-quality male insects are sterilised, commonly through irradiation, and released into the field to induce reproductive failure in females of wild populations. I worked for improving fruit fly SIT in Australia. From mass rearing techniques to quality control, shipment protocols, release methods and post-release monitoring, I performed research within the framework of the long-term strategic research and development partnership SITplus. I researched how stressors experienced by fruit flies (Bactrocera tryoni) during SIT operations can impact the ultimate male quality at the point of release, including hypoxia, irradiation, vibration, cold and hot temperatures.

Insect Monitoring


Insect monitoring is essential to gain a good understanding of insect presence and activity in crops and to assess the severity of their damages in case of outbreaks. I took part of a monitoring program for early detection of the accidentally introduced Western corn rootworm (Diabrotica virgifera virgifera) in Italian corn fields by using yellow sticky traps activated by pheromones. I monitored the establishment of introduced parasitoids in chestnut ecosystems to verify the success of a biological control camping releasing Torymus sinensis. I also took part in extensive field experiments for the Queensland fruit fly (Bactrocera tryoni), assessing the effectiveness of pre-release diet supplements, holding period and marking dyes through dispersal and survival data obtained from sticky traps and cue-lure traps.
