Factors influencing oviposition behaviour of the invasive pest, Drosophila suzukii, derived from interactions with other Drosophila species: potential applications for control

Pest Management Science, Journal Year: 2023, Volume and Issue: 79(11), P. 4132 - 4139

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. Potential semiochemical microbiome impacts postulated as determinants Development control practices reducing populations deterring them laying by utilising factors drive behaviour discussed. © 2023 The Authors.

How conspecific and allospecific eggs and larvae drive oviposition preference in Drosophila

Chemical Senses, Journal Year: 2024, Volume and Issue: 49

Published: Jan. 1, 2024

Abstract Where to lay the eggs is a crucial decision for females as it influences success of their offspring. Female flies prefer on food already occupied and consumed by larvae, which facilitates social feeding, but potentially could also lead detrimental interactions between species. Whether can modulate attraction cues associated with different species unknown. Here, we analyzed chemical profiles larvae 16 Drosophila species, tested whether would be attracted larvae-treated or from 6 The analyses revealed that larval are strongly overlapping, while egg exhibit significant specificity. Correspondingly, female preferred where they detected whatever species’ cues, found oviposition preference only some not others. Our findings suggest both present at given substrate drive in flies.

Oviposition Dynamics and Niche Utilization in Two Sympatric Drosophila Species

Journal of Chemical Ecology, Journal Year: 2025, Volume and Issue: 51(1)

Published: Feb. 1, 2025

Abstract Many Drosophila species coexist by sharing their feeding and breeding sites, which may influence oviposition choices in an interspecies social context. Whether where to lay eggs is a crucial decision for female flies as it influences the success of offspring, minimizing risk predation, competition, or cannibalism. Significant gaps exist our understanding dynamics co-occurring species. Here we tested strategies melanogaster its close relative simulans under different conditions, assess whether single would prefer oviposit separately together with another female, be conspecific not. We find that ovipositing females, regardless they are conspecifics not, at same site.

A non-overwintering urban population of the African fig fly (Diptera: Drosophilidae) impacts the reproductive output of locally adapted fruit flies

Published: Jan. 1, 2025

Abstract The African fig fly, Zaprionus indianus (Gupta) (Diptera: Drosophilidae), is a highly invasive species originally from tropical Africa that has rapidly spread across the Americas, first arriving via Brazil and subsequently Florida. Monitoring efforts have primarily focused on orchards which might underestimate actual of Z. because may also thrive in natural habitats, urban areas, other unmanaged environments are not routinely surveyed. This study investigates ability to establish non-overwintering populations its potential impact local Drosophila melanogaster (Meigen) Drosophilidae) populations. Over 41 weeks, presence population dynamics were monitored residential area Memphis, Tennessee, alongside D. . examined effects interspecific competition between these two through competitive breeding assays. Results show successfully established stable during summer fall 2023 but failed survive winter as was likely eradicated cold weather. Additionally, found reduce reproductive output females, although less severe compared intraspecific among These findings highlight need for increased monitoring areas North America, such serve reservoirs facilitating this pest into agricultural sites.

The Efficacy of Yeast Phagostimulant Baits in Attract-and-Kill Strategies Varies between Summer- and Winter-Morphs of Drosophila suzukii

Insects, Journal Year: 2022, Volume and Issue: 13(11), P. 995 - 995

Drosophila suzukii (Matsumura), is a globally invasive pest of soft and stone fruit. To survive winter in temperate zones it enters reproductive diapause morphologically distinct phenotype. Phagostimulant baits can be combined with insecticides attract-and-kill strategies for control. We investigated the effectiveness single yeast species combinations co-fermented phagostimulant when laboratory assays against both summer- winter-morph D. suzukii. Candida zemplininia or Hanseniaspora uvarum + C. lambda-cyhalothrin cyantraniliprole, H. cyantraniliprole caused significantly higher mortality winter- compared to summer-morph Additionally, M. pulcherrima resulted greater yeasts, winter-morphs summer-morphs. spinosad reduced time-to-kill (50%) summer-morphs insecticide alone.

Flies use pheromones to communicate for mating, but also serve a role reproductive isolation between related species. We asked whether pheromone modulates oviposition behaviour .

Abstract Release from competitors is one of the mechanisms ascribed to ecological success invasive species outside their native range (competitive release hypothesis). However, studies describing natural in homeland are limited. Drosophila suzukii , spotted‐wing drosophila, an pest small fruits expanding its worldwide, whereas subpulchrella most closely related D. remains endemic . inferior terms host usage capability, and it has not been considered as a major competitor This study examined interaction between two egg‐laying behaviour. A field survey revealed that 11% wild berries were co‐infected by both species. In laboratory experiments, avoided oviposition substrates had already oviposited either conspecific or females, did show any preference/avoidance toward asymmetric indicates may have negative effect on propagation niche‐sharing homeland, raising possibility competition with helped expansion populations invaded areas.
