Identification and field evaluation of the sex pheromone of a Brazilian population of Spodoptera cosmioides [PDF]

, 2016
O objetivo deste trabalho foi identificar o feromônio sexual de Spodoptera cosmioides e avaliar se existe atração cruzada em Spodoptera sp. (Lepidoptera: Noctuidae). Extratos de glândulas de S. cosmioides foram analisados por GC-FID e GC-MS.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

Sex pheromone and visual trap interactions in mate location strategies and aggregation by host-alternating aphids in the field

, 1996
Field observations were made on the responses of males and gynoparae of three host-alternating aphid species, the blackberry-cereal aphid, Sitobion fragariae (Walker), the bird cherry-oat aphid, Rhopalosiphum padi (L.) and the damson-hop aphid, Phouodon ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

The responses of Praon spp. parasitoids to aphid sex pheromone components in the field

, 1994
In autumn 1991, aphid parasitoids of the genus Praon (Hymenoptera; Braconidae) were caught in water traps with lures containing synthetic aphid sex pheromone components at three sites in England and one in Germany.

Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

Entomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]

, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Vicia faba-Lygus rugulipennis interactions: induced plant volatiles and sex pheromone enhancement

, 2009
The profiles of volatile chemicals emitted by Vicia faba plants damaged by Lygus rugulipennis feeding, and by feeding plus oviposition, were shown to be quantitatively different from those released by undamaged plants.
