Summary: A major QTL for oviposition deterrence to orange wheat blossom midge was found on chromosome 1A, inherited from the Chinese variety Sumai-3. This study identified two major effect loci affecting oviposition deterrence in wheat, providing genetic markers for trait selection.

Summary: The Swede midge is an invasive economic pest of canola that poses a threat to production in Canada. Laboratory experiments showed that canola can compensate for herbivory by increasing production of tertiary racemes and pods, but this may lead to uneven crop maturation, delayed harvest, and yield loss. Insecticides should be applied before certain densities of Swede midge are reached to prevent delays in maturation and harvest.

Summary: Soybean gall midge, a new species causing significant injury to soybean, has been found in 164 counties across 7 midwestern states in the United States. Infestation of soybean begins in late spring, and the presence of fissures at the base of the soybean plant is crucial for R. maxima infestation. Hilling, the movement of soil to cover the base of soybean plants, can effectively reduce infestation and plant injury.

Summary: The study investigated the effect of diammonium phosphate (DAP) fertilizer on the density of blueberry gall midge infestation in wild blueberry systems. Despite an increase in infestation density, wild blueberry production benefited from DAP fertilizer application.

Summary: Soybean gall midge is a newly identified pest that has caused severe economic loss to soybean fields in several states in the US. In order to assess the severity of plant injury, researchers developed an injury rating system and found that it correlates well with yield loss caused by the larvae. This system may be an important tool for understanding the economic impact of this emergent pest.

Summary: Succulent Aizoaceae plants in the Greater Cape Floristic Region of southern Africa support a rich community of previously unstudied gall midges, with a new genus Ruschiola described in this study based on morphological, molecular, and life history data. The high degree of morphological uniformity in Ruschiola species suggests recent diversification and the need for molecular data to verify species boundaries and host ranges.

Summary: In this study, the external morphology and ultrastructure of the antennae and antennal sensilla of the gall midge Gephyraulus lycantha were examined using scanning electron microscopy. Results revealed significant sexual dimorphism in antenna length and sensilla types, with different numbers of sensilla observed in male and female antennae. These findings provide important insights for future research on chemical communication and control strategies for G. lycantha, as well as potential new taxonomic characters for cecidomyiidae species.

Summary: The chemosensory genes in the pine needle gall midge have been identified and classified, providing a basis for further research on functional analysis. This research could potentially contribute to the development of environmentally friendly pest management methods. The expression profiles of certain chemosensory genes were also validated through quantitative real-time PCR.

Summary: The laboratory rearing method for orange wheat blossom midge has been successfully developed for over 20 years in Winnipeg, Canada. The method includes techniques to extend adult survival, increase oviposition, prevent desiccation of larvae, and break larval diapause, providing data for coordinating wheat midge emergence with susceptible periods. This method can be scaled for resistance screening or small experiments on pest management.

Summary: This study found that certain wheat volatiles can attract Sitodiplosis mosellana for oviposition, while others have repellent effects. Several odor components related to host selection of S. mosellana were identified. These findings are important for the development of semi-chemical pest management.

Summary: This study presents a synthetic approach to produce the orange wheat blossom midge (Sitodiplosis mosellana) sex pheromones. The method achieved high enantioselectivity and overall yields in a short period, while conventional methods required longer synthesis time with lower yields. The synthesized pheromones demonstrated significant attractiveness to S. mosellana males in laboratory tests and field trials.

Summary: The blueberry gall midge is an economically important insect pest of blueberry and cranberry, and has spread worldwide. Through population genetic analysis, we found clear separation between blueberry and cranberry-associated gall midge populations, suggesting they may be two distinct species. Our study also suggests multiple introductions of gall midge populations in Korea. This research is important for understanding the source and invasion process of the gall midge and its association with different host plants.

Summary: A new gall midge species, Spanolepis selloanae, is reported for the first time in southern Spain, feeding on the ovaries of the invasive grass Cortaderia selloana and potentially serving as an effective biological control agent. The larvae of this species cause a significant depletion in seed production, indicating its potential impact on limiting the reproductive success of the invasive plant species.

Summary: This study investigated the chemical response of Salicornia europaea plants to infestation by a gall midge fly. The results showed that different degrees of infestation led to changes in the chemical composition of the plants, and several new compounds were identified in the infested branches. Furthermore, the study found that the infestation induced the production of a higher number of specialized metabolites with important biological activities.

Summary: The soybean gall midge, a recently identified species, has been causing significant damage to soybean fields in the Midwestern United States, with yield losses of up to 100% near the field edge. This rapid development of the soybean gall midge as a major pest has created gaps in knowledge essential for developing effective pest management programs.
