Signals in Flux: Investigating the Seasonal Turnover of the Diel Vertical Migration‐Inducing Kairomone 5α‐Cyprinol Sulfate

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT 5α‐Cyprinol sulfate (CPS), a kairomone released by cyprinid fishes, induces diel vertical migration (DVM) in Daphnia and thus shapes ecosystem dynamics wherever both taxa co‐occur. Here, we provide the first in situ quantification of CPS turnover, revealing strong temporal variability in this chemical signal and its ecosystem‐wide consequences

Laboratory Evaluation of Natural and Synthetic Aromatic Compounds as Potential Attractants for Male Mediterranean fruit Fly, Ceratitis capitata

open access: yesMolecules, 2019
Ceratitis capitata, the Mediterranean fruit fly, is one of the most serious agricultural pests worldwide responsible for significant reduction in fruit and vegetable yields. Eradication is expensive and often not feasible. Current control methods include

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]

open access: yes, 2017
Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

Flight attraction of Spodoptera littoralis (Lepidoptera, Noctuidae) to cotton headspace and synthetic volatile blends

open access: yesFrontiers in Ecology and Evolution, 2015
The insect olfactory system discriminates odor signals of different biological relevance, which drive innate behavior. Identification of stimuli that trigger upwind flight attraction towards host plants is a current challenge, and is essential in ...

Ethology and Overwintering of \u3ci\u3ePodalonia Luctuosa\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
The nesting and overwintering behavior of Podalonia luctuosa (Smith) was studied in New York and Colorado. Females provisioned shallow (ca. 2 cm deep), unicellular nests with a single cutworm (Noctuidae) during April, May, and July.

Utility of essential oils for development of host-based lures for Xyleborus glabratus (Coleoptera: Curculionidae: Scolytinae), vector of laurel wilt

open access: yesOpen Chemistry, 2018
Redbay ambrosia beetle, Xyleborus glabratus, is native to Southeast Asia, but subsequent to introduction in Georgia in 2002, it has become a serious invasive pest in the USA, now established in nine southeastern states. Females vector Raffaelea lauricola,

Target gene approaches: Gene expression in Daphnia magna exposed to predator-borne kairomones or to microcystin-producing and microcystin-free Microcystis aeruginosa

open access: yesBMC Genomics, 2009
Background Two major biological stressors of freshwater zooplankton of the genus Daphnia are predation and fluctuations in food quality. Here we use kairomones released from a planktivorous fish (Leucaspius delineatus) and from an invertebrate predator ...

Persistent maternal identity effects on life history traits in Daphnia [PDF]

open access: yes, 2018
The aim of the present study was to examine the magnitude and persistence of maternal effects in Daphnia, in particular maternal identity effects. I studied life history traits of a single clone of Daphnia galeata born to 40 different mothers belonging ...

Morphological and life‐history trait plasticity of two Daphnia species induced by fish kairomones

open access: yesEcology and Evolution
Daphnia can avoid predation by sensing fish kairomones and producing inducible defenses by altering the phenotype. In this study, the results showed that the morphological and life‐history strategies of two Daphnia species (Daphnia pulex and Daphnia ...
