Common milkweed gardens increase occupancy by monarch butterflies and other specialist herbivores towards an urban centre

open access: yesInsect Conservation and Diversity, EarlyView.
We surveyed 119 stands of common milkweed (Asclepias syriaca) across an urbanisation gradient to investigate how restored garden habitat might ameliorate the negative effects of urbanisation on specialist herbivores. Surprisingly, we found most herbivores (including the monarch butterfly) had greater occupancy on common milkweed towards an urban centre.

First report of Rhopalosiphum nymphaeae (L.) (Hem.: Aphididae) on Azolla filiculoides from Iran and its male formation on secondary host plant

open access: yesJournal of Crop Protection, 2015
To determine the effective bio-control agents of water fern, Azolla filiculoides, adults and nymphs of water lily aphid, Rhopalosiphum nymphaeae (L.), were collected on A. filiculoides in Guilan Province, Iran, during October 2013.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Effects of autumn kaolin, pyrethrin, and ladybird larvae (Adalia bipunctata) applications on the spring populations of the rosy apple aphid (Dysaphis plantaginea) in an on-farm apple orchard (cv. Topaz) [PDF]

open access: yes, 2003
Effects of different strategies (insecticide treatment, physical barrier, biocontrol) to control autumn forms of Dysaphis plantaginea. Question 1: Efficacy of pyrethrum, kaolin, and larvae of A. bipunctata to control Dysaphis plantaginea.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

open access: yesInsect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

The Interactive Effect of Pesticides, Heat Stress, and Population on the Performance of a Mite Pest, Tetranychus Urticae

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Global warming is a cause for concern and is predicted to diversely affect agricultural systems. One aspect of the predicted effects is the susceptibility of pests to chemical pesticides. It is therefore crucial to study the reaction of pests to different pesticide compounds under different temperatures in order to better predict how those ...
