Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Toxicity and synergism of the essential oil of Piper aduncum L. in populations of Sitophilus zeamais(Coleoptera: Curculionidae)

Pesquisa Agropecuária Tropical, 2023
Researches on the use of essential oil of Piper aduncum L. (EOPA) as a synergist in stored grain pests are still incipient. This study aimed to determine the toxicity of deltamethrin and EOPA, as well as to study the effect of the binary mixture of EOPA +

Robel Pole Method Can Estimate Cereal Rye Biomass to Optimize Termination Timing

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Fully realizing the benefits of cover crops and minimizing the yield penalty requires knowing when to terminate them. Cereal rye (Secale cereale L.) is the dominant cover crop used in the Midwest US, and previous work has shown that corn (Zea mays L.) yield penalties began to occur more frequently when cereal rye is at ∼1000 lb dry biomass ac ...

Preventing Invasive Non‐Native Species: A Horizon Scanning for the Canary Islands

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Oceanic islands host exceptional biodiversity and endemism but are highly vulnerable to biological invasions. We aimed to identify non‐native species with high potential to invade the Canary Islands within the next decade and to prioritise them based on their environmental and socioeconomic risks.
