Article
Full-text available
A long-standing enigma concerns the geographic and ecological origins of the intensively studied vinegar fly, Drosophila melanogaster. This globally distributed human commensal is thought to originate from sub-Saharan Africa, yet until recently, it had never been reported from undisturbed wilderness environments that could reflect its pre-commensal...

Full-text available
Although the vinegar fly Drosophila melanogaster is arguably the most studied organism on the planet, fundamental aspects of this species’ natural ecology have remained enigmatic [1]. We have here investigated a wild population of D. melanogaster from a mopane forest in Zimbabwe. We find that these flies are closely associated with marula fruit (Sc...
Preprint
A long-standing enigma concerns the geographic and ecological origins of the intensively studied vinegar fly, Drosophila melanogaster, a globally widespread species which has invariably appeared to be a strict human commensal. In spite of its sub-Saharan origins, this species has never been reported from undisturbed wilderness environments that mig...

Seed orchards function as the primary source of high-quality seeds for reforestation in many European countries, but their seed yields can be severely reduced due to seed- and cone-feeding insects. We evaluated various parameters of pheromone-based mating disruption for control of the moths Cydia strobilella and Dioryctria abietella, which are majo...
Article
Full-text available
The sex pheromone of the cloaked pug moth, Eupithecia abietaria G€otze, an important cone-feeding pest in spruce seed orchards in Europe, was investigated. Chemical and electrophysiological analyses of pheromone gland extracts of female moths and analogous analyses of synthetic hydrocarbons and epoxides of chain length C19 and C21 revealed (3Z,6Z,9...
Article
Combining pheromone trapping and genetic analyses can be useful when trying to resolve complexes of closely related insect taxa that are difficult to distinguish based on morphological characters. Nearctic and Palearctic populations of the spruce seed moth, Cydia strobilella L., have been considered taxonomically synonymous since 1983, but more rec...
Article
Full-text available
The spruce coneworm, Dioryctria abietella Denis & Schiffermüller (Lepidoptera: Pyralidae), is a major pest in spruce seed orchards in Europe. Initial work on its pheromone ecology reported significant attraction of males to (9Z,11E)-tetradecadienyl acetate (9Z,11E-14:OAc), but this compound appeared to be a very weak attractant in field trials. In...

The spruce seed moth, Cydia strobilella L., is a serious pest on cones of spruce (Picea spp.) in the Holarctic region. Previous studies from different parts of its area of distribution have reported conflicting results on the composition of its sex pheromone. By gas chromatography with electroantennographic detection, coupled gas chromatography-mas...

Three pyralid moths, the Mediterranean flour moth (Ephestia kuehniella), the almond moth (Ephestia cautella) and the Indian meal moth (Plodia interpunctella), infest food products all over the world and cause severe problems in factories, shops and households. For health and environmental reasons chemical control becomes more and more restricted. W...

In the caddisfly Molanna angustata, females produce a sex pheromone in glands with openings on the fifth sternite. Gas chromatographic analyses of pheromone gland extracts with electroantennographic detection revealed four major compounds that stimulated male antennae. These compounds were identified by means of gas chromatography-mass spectrometry...

Inula conyzae was discovered in Vellinge, southwestern Skåne in July 2007 Twenty-seven plants were found along a slope leading down to a small pond, and eight more individuals were discovered on a field nearby. The population seems to be several years old, and will hopefully expand. This is the first record of I. conyzae in Sweden since 1974. We di...
Article
The currant shoot borer, Lampronia capitella (Lep., Prodoxidae), is an important pest of currants, Ribes spp., in northern Europe. Oviposition was studied in cage experiments and the flight period was monitored in field studies using pheromone-baited traps. Blackcurrant, Ribes nigrum, was the host species in both studies. The total egg supply of fe...
Article
Full-text available
Under an artificial light:dark cycle, females of Lampronia capitella were observed calling, with extended terminal abdominal segments, during the first 2 hr of the photoperiod. Extracts of terminal abdominal segments from females elicited large electroantennographic responses from male antennae. Gas chromatography with electroantennographic detecti...

Females of the European pine sawfly, Neodiprion sertifer (Geoffr.) (Hymenoptera: Diprionidae), were released and observed inside and outside (=control) of areas treated with their sex pheromone for the purpose of mating disruption. In 1992 and 1993, respectively, 0 and 2.5% of the females were observed mating in the pheromone treated area during th...
