“…Gall midge pheromone identifications require state-of the-art analytical techniques, since they are produced in pico-to femtogram amounts. The chemical structures are carbon chains with one or two ester functionalities, and have been identified from several species including Hessian fly Mayetolia destructor (Andersson et al 2009), swede midge Contarinia nasturtii (Hillbur et al 2005), and raspberry cane midge Resseliella theobaldi (Hall et al 2009). Swede midge traps have been deployed along the US-Canadian border to determine the geographical range of this invasive insect.…”

The idea of using species-specific behavior-modifying chemicals for the management of noxious insects in agriculture, horticulture, forestry, stored products, and for insect vectors of diseases has been a driving ambition through five decades of pheromone research. Hundreds of pheromones and other semiochemicals have been discovered that are used to monitor the presence and abundance of insects and to protect plants and animals against insects. The estimated annual production of lures for monitoring and mass trapping is on the order of tens of millions, covering at least 10 million hectares. Insect populations are controlled by air permeation and attract-and-kill techniques on at least 1 million hectares. Here, we review the most important and widespread practical applications. Pheromones are increasingly efficient at low population densities, they do not adversely affect natural enemies, and they can, therefore, bring about a long-term reduction in insect populations that cannot be accomplished with conventional insecticides. A changing climate with higher growing season temperatures and altered rainfall patterns makes control of native and invasive insects an increasingly urgent challenge. Intensified insecticide use will not provide a solution, but pheromones and other semiochemicals instead can be implemented for sustainable area-wide management and will thus improve food security for a growing population. Given the scale of the challenges we face to mitigate the impacts of climate change, the time is right to intensify goal-oriented interdisciplinary research on semiochemicals, involving chemists, entomologists, and plant protection experts, in order to provide the urgently needed, and cost-effective technical solutions for sustainable insect management worldwide.

“…Analysis by coupled gas chromatographic-electroantennographic detection (GC-EAD) has proved effective at detecting pheromone components in collections from female Cecidomyiidae, with the male antenna capable of detecting components below a GC threshold of detection (Hillbur et al, 1999;Gries et al, 2002;Choi et al, 2004). Specially designed Plexiglas holders have been used for the antennal preparation (Hillbur et al, 2001(Hillbur et al, , 2005Andersson et al, 2009a), while Gries et al (2002) used a severed head and antenna suspended between two glass electrodes. Male midges generally have long antennae relative to their bodies, and EAD preparations can be made by inserting a body into the glass reference electrode, after first removing wings and head, and then inserting one or both antennae into the recording electrode (Birkett et al, 2004;Amarawardana, 2009;Hall et al, 2009;Molnár et al, 2009).…”

The family of cecidomyiid midges (Diptera: Cecidomyiidae) exhibits diversified patterns of life history, behavior, host range, population dynamics and other ecological traits. Those that feed on plants include many important agricultural pests; most cultivated plants are attacked by at least one midge species. Several features of the reproductive biology of cecidomyiid midges point to an important role for chemical communication, with this topic last reviewed comprehensively 12 years ago. Here, we review progress on identification of sex pheromones, chemicals involved in location of host plants, the neurophysiology of reception of volatile chemicals, and application of semiochemicals to management of pest species of cecidomyiid midges that has occurred during the last decade. We hope this review will stimulate and sustain further research in these fields.

“…The current pest management of C. nasturtii is based on pheromone traps that predominantly attract males (Hillbur et al, 2005). This study has demonstrated some candidate volatile mixtures that are likely attractive to female swede midges, which could be used to develop volatile lures to control the female population.…”

Host Attraction and Selection in the Swede Midge (Contarinia nasturtii)

Gall midges (Diptera: Cecidomyiidae) are a speciose family that, as adults, are short lived (lasting only a few days), they use olfactory cues for host and mate localization, and their host plant specificity is a key characteristic of the family. These traits make them good models with which to study the role of olfaction in speciation. The overall objective of this study was to analyze the host selection behavior of the gall midge, Contarinia nasturtii, a crucifer specialist that also is a crucifer pest. Here, we demonstrate that the host specificity of gravid C. nasturtii females was initiated by the olfactory-driven host plant choice during oviposition. Olfactory preference of the female, while narrow, encompassed more plants than were accepted for egg-laying, indicating that other factors following the initial olfactory attraction are involved in ultimate host choice. Similarly, C. nasturtii showed flexibility in host plant choice depending on which plants were available for oviposition. Larvae developed on host plants selected by females for oviposition. This slightly broader range of olfactory preference over acceptance, and the flexibility in host choice, might be the basis for the rapid speciation reported in the gall midge family. Furthermore, we assessed whether ubiquitous and/or family-specific plant odors are involved in the attraction of gravid C. nasturtii to their hosts. For that, we used the crucifer Arabidopsis thaliana, which has a broad range of defined ecotypes and large number of mutants. The attraction of C. nasturtii to two A. thaliana-types were tested; one that does not produce the ubiquitous green leaf volatiles (Columbia, Col-0), and a knock-out mutant which does not produce the crucifer-specific glucosinolates. Surprisingly, C. nasturtii was attracted to both types, indicating that neither of these compounds, nor their breakdown products (e.g., isothiocyanates), are essential for C. nasturtii host attraction.
