Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 2. Methods to Improve Overwintering, Adult Emergence and Longevity

Entomologia Experimentalis et Applicata, EarlyView.
Successful rearing of Istocheta aldrichi, a tachinid parasitoid of invasive Japanese beetle, depended on conditions before, during, and after overwintering. Longer cold exposure increased adult emergence and accelerated post‐diapause development. Early transfer of puparia to cool conditions improved survival, while spring temperature manipulation ...

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.

Novel Sex Cells and Evidence for Sex Pheromones in Diatoms

PLoS ONE, 2011
Diatoms belong to the stramenopiles, one of the largest groups of eukaryotes, which are primarily characterized by a presence of an anterior flagellum with tubular mastigonemes and usually a second, smooth flagellum. Based on cell wall morphology, diatoms have historically been divided into centrics and pennates, of which only the former have flagella ...

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

Ecological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Pheromone gland development and pheromone production in Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae)

, 2011
The sand ßy Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae: Phlebotominae) is the main vector of American visceral leishmaniasis. Adult males produce a terpenoid sex pheromone that in some cases also acts as male aggregation pheromone.

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

Ecological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Two Sympatric Spodoptera Species Could Mutually Recognize Sex Pheromone Components for Behavioral Isolation

Frontiers in Physiology, 2019
Spodoptera exigua and S. litura are two sympatric species in China and many other countries. Both moths employ a multiple component sex pheromone blend, including a common component Z9,E12-14:OAc, and two specific components Z9-14:OH and Z11-16:OAc for S.

Synthesis of 9-methylgermacrene B, racemate of the sex pheromone of Lutzomyia longipalpis (Lapinha), from the renewable source, Geranium macrorrhizum essential oil

, 2006
The sex pheromone of Lutzomyia longipalpis (Lapinha), comprising the unusual homosesquiterpene, 9-methylgermacrene B, can be prepared by methylation and deoxygenation of germacrone, the major constituent of Zdravets oil, the essential oil of the ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Ant trail pheromone biosynthesis is triggered by a neuropeptide hormone.

PLoS ONE, 2012
Our understanding of insect chemical communication including pheromone identification, synthesis, and their role in behavior has advanced tremendously over the last half-century.
