Temperature requirements of some aphids and their parasites
The rate of insect development depends upon the temperature to which the insects are exposed. For each species, the temperature below which no measurable development occurs is its threshold of… Expand
Predators, parasitoids and pathogens.
Invitation paper: C.P. Alexander Fund. Host choice by aphidiid parasitoids (Hymenoptera: Aphidiidae): host recognition, host quality, and host value.
A conceptual model of host choice by aphidiid wasps is presented and host value varies dynamically with parasitoid state variables such as age, egg load, and prior experience. Expand
Instar-specific defense of the pea aphid,Acyrthosiphon pisum: Influence on oviposition success of the parasiteAphelinus asychis (Hymenoptera: Aphelmidae)
Observed patterns of preference by Aphelinus females for particular aphid species and instars reflect the outcome of behavioral interactions between the hosts and the parasites, rather than preference in the strict sense. Expand
Oviposition and host‐feeding patterns in Aphelinus asychis (Hymenoptera: Aphelinidae) at different aphid densities
Abstract. 1. The patterns of host‐feeding and oviposition were examined in Aphelinus asychis Walker, which had been provided with second‐instar pea aphids as hosts.
OVIPOSITION BEHAVIOUR OF APHIDIINE WASPS (HYMENOPTERA: BRACONIDAE, APHIDIINAE): MORPHOLOGICAL ADAPTATIONS AND EVOLUTIONARY TRENDS
It is suggested that the main driving forces in the evolution of parasitoid oviposition behaviour were aphid defensive behaviour and avoidance of aggression by trophobiotic ants. Expand
Economic impact of biological control of weeds and insects.
Phylogenetic relationships among genera of Aphidiinae (Hymenoptera: Braconidae) based on DNA sequence of the mitochondrial 16S rRNA gene
Phylogenetic relationships among forty‐nine taxa representing twenty‐four genera of Aphidiinae (Hymenoptera: Braconidae) were investigated using DNA sequence of a portion of the mitochondrial 16S rRNA gene and parsimony analysis, suggesting that members of Aphidisinae are monophyletic. Expand
