Evidence for a defensive ceiling in the effectiveness of plant silicon defences against an insect herbivore

Ecological Entomology, EarlyView.
Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

Ecological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Number of larval instars in Plutella xylostella (L.) (Lepidoptera: Yponomeutidae)

, 2008
O presente trabalho teve como objetivo determinar indiretamente o número de ínstares larvais em Plutella xylostella. No Laboratório de Biologia de Insetos da Universidade Federal de Viçosa, à temperatura de 24,5±4ºC, fotofase de 12 horas e UR de 70±5%, lagartas foram alimentadas em placas de Petri com folhas frescas de repolho.

Canopy position and tree size structure the distribution of honeydew‐producing scale insects (Hemiptera: Coccoidea) in a temperate hardwood forest

Ecological Entomology, EarlyView.
Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.
