Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Gall insects and indirect plant defenses [PDF]

open access: yesPlant Signaling & Behavior, 2008
Many plants can defend themselves against insect herbivory by attracting natural enemies that kill feeding herbivores and limit the damage they inflict. Such "indirect defenses" can be induced by insects feeding on different plant tissues and using a variety of feeding styles.

The Plant‐Associated Fungus Chaetomium globosum Can Directly Infect and Kill Aphids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Plant‐associated Chaetomium globosum strains caused direct infection and mortality in cotton aphids (Aphis gossypii) under different concentration‐dependent pathogenicity bioassays. Reinfection, aphid mortality, fungal re‐isolation, and molecular identification confirmed fulfillment of Koch's postulates for insect pathogenicity. These findings revealed

Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

open access: yesEcological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.
