Abstract The invasive fly Drosophila suzukii is a pest that can infest diverse range of intact, ripening fruits, using its serrated ovipositor. This constitutes different niche compared to the rotting fruits ancestors use, especially because these intact have limited quantities microbes and soluble nutrients for developing larvae. To investigate potential role microbial associations in expansion this fly, we characterized bacterial fungal communities D. various wild from which they developed. assess cross-generational associations, also lab-reared populations their communities. Diversity metrics differed significantly between flies fruits. Different fruit types varied substantially composition, while showed relatively uniform communities, irrespective source developed on. After approximately ten generations lab-rearing, still considerable overlap with those flies. Fungal larger resemblance, substantial on had Our study thus reports community structure pests largely reflects breeding substrates, might formed more persistent some bacteria transmit across generations.

Following the concept of holobiont, insect-microbiota interactions play an important role in insect biology. Many examples host-associated microorganisms have been reported to drastically influence biological processes such as development, physiology, nutrition, survival, immunity, or even vector competence. While a huge number studies on insect-associated microbiota focused bacteria, other microbial partners including fungi comparatively neglected. Yeasts, which establish mostly commensal symbiotic relationships with their host, can dominate mycobiota certain insects.

Drosophila suzukii (Matsumura) or spotted wing is a worldwide invasive pest of soft- and stone-fruit production. Female D. lay their eggs in ripening fruit the hatched larvae damage from inside, rendering it unmarketable causing significant economic loss. Current methods to reduce population field primarily rely on chemical insecticides which are not sustainable long-term solution increase risk resistance developing. Several studies demonstrate that when encounter coexist with other food source, this usually disadvantage suzukii, leading reduced oviposition increased larval mortality. These effects have potential be exploited management perspective. In review we summarise recent research articles focusing interspecific interactions between species aimed at understanding how drives behaviour.

Abstract Ceratitis capitata (Wiedemann) is a cosmopolitan pest of economic importance. It controlled by using the Sterile Insect Technique (SIT), which involves rearing and release sterile males destined to mate with wild females, causing generation‐to‐generation suppression. Medflies are colonized microorganisms, primarily Enterobacteriaceae, genera Klebsiella Enterobacter being most common. Such microbiota contributes host fitness. During SIT, diet antibiotics irradiation for sterility adults alter microbiota. We aimed determine role Medfly on resistance abiotic stress conditions, evaluating its function under: (i) starvation, (ii) elevated temperatures, (iii) dry environments. These conditions simulate challenges may encounter after release, differ from compared adult survival between symbiotic aposymbiotic individuals, under two thermal regimes (25 30 °C) or humidity (20%–25% 80%–90% R.H.). Aposymbiotic individuals were obtained providing them water containing mixture methylparaben. Treatment antimicrobials effectively reduced gut While starvation had no significant effect survival, higher proportion died earlier at °C humidity, more pronounced 48 h.

The invasive pest, Drosophila suzukii attacks fresh soft-skinned fruit. Broad-spectrum insecticides are implemented for control but there is a need to reduce environmental risks and insecticide residues on fruits. Hanseniaspora uvarum yeast frequently found ripe fruits associated with D. suzukii. We aim exploit the ecological association attraction of H. by developing an attract-and-kill strategy, spray-application canopy not therefore investigated attraction, egg-laying mortality when exposed insecticidal yeast-based formulations.Hanseniaspora strongly attracted applied leaves grapevine, Vitis vinifera. Notably, this attractiveness was competitive grape berries that were susceptible infestation. Moreover, adding enhanced efficacy formulations against Flies treated yeast-insecticide showed higher laid lower number eggs compared flies alone. In wind tunnel, all treatments containing alone or in combination insecticides, caused similar upwind flight landing at odor source, which provides evidence addition did yeast.Hanseniaspora can be used manipulate behavior attracting formulations. Yeast improves effectiveness, suggesting sprays covering only, could fruit without compromising management efficacy.
