“…Harmonic radar allows tracking hornets only over short distances, but is not suited to follow several signals at the same time, and it is not accurate enough (Milanesio et al., 2016, 2017): The RFID provides the best compromise to acquire new information on workers’ flight behavior that are of first interest for the monitoring and control of this special invasive hornet. Invasive social insects, especially vespids, can deeply affect their environments (Beggs et al., 2011; Bradshaw et al., 2016), and their impact is obviously related to foraging range. How animals use their environment and their movements is key parameters in biological invasion (Holway & Suarez, 1999), and such parameters should be implanted in future impact models.…”

In social insects, the activity rhythm of foragers and their action range determinate the activity of the colony. In vespids, which are mostly predators, the foraging range of workers determines their maximum predation pressure round the nest. One of these species, Vespa velutina, a recently invasive species introduced into Europe, exerts a strong predation on honeybees at the hive. Therefore, the definition of its activity rhythm and spatial range of predation is of primary importance. Using radio frequency identification tags (RFID), two experiments were carried out to (a) determine their return ability (called homing) in releasing 318 individuals at different distance from their colony and (b) monitor their foraging activity rhythm and the duration of their flights based on 71 individuals followed 24 hr/24 during 2 months. The homing ability of V. velutina was evaluated to be up to 5,000 m and was not affected by the cardinal orientation of release point. The lag time to return to the nest increased with the distance of release. Most of the flight activity took place between 07:00 a.m. and 08:00 p.m., hornets doing principally short flights of less than an hour. Foraging range was thus estimated ca. 1,000 m around the nest. This study of V. velutina assisted by RFID tags provides for the first time a baseline for its potential foraging distance that increase our knowledge of this species to (a) refine more accurately models for risk assessment and (b) define security perimeter for early detection of predation on invasion front.

“…The human population will reach over 9 billion people by 2015, and international trade and climate change continue to drive increasing introductions of invasive phytophagous insects (Bradshaw et al 2016, Seebens et al 2017). This presents an extreme challenge to modern agriculture and requires a significant shift towards sustainable practices that can meet the demand for food whilst limiting harmful effects on the environment.…”

A response to Pennisi - “How do gut microbiomes help herbivores”, a hint into next-generation biocontrol solutions

In a world where invasive invertebrate species can significantly compromise food security and where a dwindling range of synthetic pesticides remains our principal line of defence, testing a new invasion ecology hypothesis and understanding what makes a phytophagous insect invasive should be regarded as high priority research. Recent advances in microbiology strongly support the crucial and effective role of the gut microbiome in insect growth, development and, most importantly, environmental adaptation to their host plants. On the basis of recent literature, and following Elizabeth Pennisi's article published in the journal Science, we hypothesis that gut microbiome could be a critical determinant of invasion success in phytophagous insects, and that the uncovering of common traits in the gut microbiome of invasive insects, a "gut microbiome invasiveness signature", would open new avenues of research towards nextgeneration biocontrol solutions.

“…This expanding demand has led to increases in agricultural monocultures, which exacerbate yield losses to pest species (2,3). Moreover, rapid evolution of pest resistance to chemical control (4), combined with the negative impacts of pesticides on human health and the environment, has increased calls for sustainable and acceptable pest management methods (5)(6)(7).…”

Increased regulation of chemical pesticides and rapid evolution of pesticide resistance have increased calls for sustainable pest management. Biological control offers sustainable pest suppression, partly because evolution of resistance to predators and parasitoids is prevented by several factors (e.g., spatial or temporal refuges from attacks, reciprocal evolution by control agents, and contrasting selection pressures from other enemy species). However, evolution of resistance may become more probable as agricultural intensification reduces the availability of refuges and diversity of enemy species, or if control agents have genetic barriers to evolution. Here we use 21 y of field data from 196 sites across New Zealand to show that parasitism of a key pasture pest (Listronotus bonariensis; Argentine stem weevil) by an introduced parasitoid (Microctonus hyperodae) was initially nationally successful but then declined by 44% (leading to pasture damage of c. 160 million New Zealand dollars per annum). This decline was not attributable to parasitoid numbers released, elevation, or local climatic variables at sample locations. Rather, in all locations the decline began 7 y (14 host generations) following parasitoid introduction, despite releases being staggered across locations in different years. Finally, we demonstrate experimentally that declining parasitism rates occurred in ryegrass Lolium perenne, which is grown nationwide in high-intensity was significantly less than in adjacent plots of a less-common pasture grass (Lolium multiflorum), indicating that resistance to parasitism is host plant-dependent. We conclude that low plant and enemy biodiversity in intensive large-scale agriculture may facilitate the evolution of host resistance by pests and threaten the long-term viability of biological control.attack rates | GAMM | invasive species | meta-analysis | natural enemy
