Adaptive preferential selection of female coccinellid hosts by the parasitoid wasp Dinocampus coccinellae (Hymenoptera: Braconidae) [PDF]

open access: yesEuropean Journal of Entomology, 2006
Females of the parasitoid wasp Dinocampus coccinellae are known to parasitise both male and female coccinellid hosts. It is suggested that female hosts provide more resources for developing wasp larvae because they tend to be larger than male hosts, and ...

Foraging in a complex environment - semiochemicals support searching behaviour of the seven spot ladybird [PDF]

open access: yesEuropean Journal of Entomology, 2005
Knowledge of semiochemically-mediated behavioural mechanisms of the seven-spot ladybird, Coccinella septempunctata L., is limited but sufficient to encourage further studies in the behavioural ecology of this well known insect.

Laboratory Investigations Reveal that Harmonia axyridis (Coleoptera: Coccinellidae) Is a Poor Host for Dinocampus coccinellae (Hymenoptera: Braconidae) in Brazil. [PDF]

open access: yesJ Insect Sci, 2016
Harmonia axyridis (Pallas, 1773) is an Asian coccinellid released in several places to act as a biological control agent of aphids. Dinocampus coccinellae (Schrank, 1802) is an endoparasite that uses more than 40 coccinellid species as hosts. Thus, the aim of this study was to investigate the interactions between D. coccinellae and H.

Dinocampus coccinellae (Hymenoptera: Braconidae) utilizes both Coccinellini and Chilocorini (Coleoptera: Coccinellidae: Coccinellinae) as hosts in Kashmir Himalayas [PDF]

open access: yesEuropean Journal of Entomology, 2018
Dinocampus coccinellae is a parasitoid wasp usually parasitizing ladybird beetles of the tribe Coccinellini. A field survey conducted between March and November 2016 revealed three hosts of this parasitoid in the Srinagar district of the Indian state of ...

Aphids-induced plant volatiles affect diel foraging behavior of a ladybird beetle Coccinella septempunctata. [PDF]

open access: yesInsect Sci, 2020
Abstract The ladybird beetle Coccinella septempunctata (L.) is an important biocontrol agent of pests such as various aphid species. Despite being one of the most studied coccinellid species, many aspects of its foraging behavior are still not completely understood. This study focuses on the diel foraging behavior of C.

Study of anatomical changes in Coccinella septempunctata induced by diet and by infection with the larva of Dinocampus coccinellae using magnetic resonance microimaging [PDF]

open access: yesEuropean Journal of Entomology, 2000
A range of nuclear magnetic resonance (NMR) techniques, 1H liquid spectroscopy and T1 and T2 relaxation measurements, and microimaging, have been used to observe changes taking place within the bodies of live samples of Coccinella septempunctata, under a

Male-killer symbiont screening reveals novel associations in Adalia ladybirds. [PDF]

open access: yesAccess Microbiol, 2023
While male-killing bacteria are known to infect across arthropods, ladybird beetles represent a hotspot for these symbioses. In some host species, there are multiple different symbionts that vary in presence and frequency between populations.

Dinocampus coccinellae as a parasitoid of the invasive ladybird Harmonia axyridis in Europe [PDF]

open access: yesBiological Control, 2010
Abstract The enemy release hypothesis states that the absence of effective natural enemies can be a fundamental aspect leading to the successful establishment of an invasive species. This study investigates the impact of the native braconid parasitoid Dinocampus coccinellae on European populations of the invasive ladybird Harmonia axyridis.
