The accumulation of metalloid elements during transfer from contaminated soil to higher trophic levels may potentially result in the exposure of parasitic arthropods to toxic concentrations of these elements. This study examined the transfer of arsenate (

Patch residence decisions made by Aphidius colemani in the presence of a facultative predator
Biological Control, 2009Abstract One of the key questions in ecology is how animals optimally allocate their time in an environment with patchily distributed resources and competing organisms. Here we investigate the effects that an aphid predator, Macrolophus caliginosus (Wagner) (Hemiptera: Miridae), has on the searching behavior and the patch residence decisions of an ...

Compact plants reduce biological control of Myzus persicae by Aphidius colemani
Biological Control, 2013Common horticultural practices, such as the use of plant growth regulators, may negatively influence the outcome of biological control programs. Plant growth regulators are applied to many ornamental and agricultural crops and can result in compact plants that have more branches and are bushier than untreated plants.

Host instar and host plant effects on Aphidius colemani
Journal of Applied Entomology, 2007Abstract: The effect of Myzus persicae age (I–IV instar nymphs) on parasitism by Aphidus colemani was investigated in choice experiments with either aubergine (Solanum melongena L.) or pepper (Capsicum annuum L.) as the aphid host plant species. Aphidius colemani could develop successfully to the mummy stage in all ages of aphid tested, on both pepper

Induction of a thelytokous reproduction in the Aphidius colemani (Hym., Aphidiidae) complex
Journal of Applied Entomology, 1988AbstractA thelytokous parthenogenesis has been documented in the course of hybridization tests between three populations of the Aphidius colemani Viereck complex, collected in Southern Brazil, La Reunion Island and Southern France. This kind of parthenogenesis is rare in the family Aphidiidae and previously unreported in the genus Aphidius.

The functional response of two aphid parasitoids, Aphidius colemani Viereck and Aphidius matricariae (Haliday) (Hymenoptera: Aphidiidae), on the cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae), was examined. Five constant temperatures (10, 15, 20, 25, and 30°C) and six host densities (2, 4, 8, 16, 32, and 64) were used during a 24-h period ...

The introduction and establishment of Aphidius colemani Viereck (Hym., Aphidiinae) in Tonga
Journal of Applied Entomology, 1994AbstractIn this paper we describe the introduction and establishment of the polyphagous parasitoid Aphidius colemani into Tonga in an attempt to control the banana aphid, Pentalonia nigronervosa. P. nigronervosa is a serious pest of Musa spp. because of direct feeding damage and, more importantly, as a vector for banana bunchy top virus disease.

Abstract The impact of fluctuating thermal regimes on the cold tolerance of the parasitoid Aphidius colemani at the mummy stage is examined. The hypothesis is tested that, if a cold period is interrupted by a return to a higher temperature for a short time, a physiological

Nymphs of presumptive winged gynoparae of Aphis fabae (Hemiptera: Aphididae), were exposed to female parasitoids, Aphidius colemani (Hymenoptera: Aphidiidae) and stung once with the ovipositor. Wing development was inhibited and, when aphids were parasitised during the early stages, they did not reach the adult stage but mummies with rudimentary or no ...
