Summary: Berries are economically important agricultural products in Mexico, and their production has been increasing. However, tortricid leafrollers have been affecting berry crops. A study conducted in Michoacan and Guanajuato, Mexico, identified the species of tortricids associated with blackberries, raspberries, and strawberries, as well as their altitudinal distribution. The study found two commonly occurring species of tortricids, namely Amorbia cuneana and Argyrotaenia montezumae, at elevations ranging from 1290 to 2372 m. Further research is needed to determine the distribution of tortricids in other berry-producing regions.

Summary: The study identified 66 odorant receptors in the codling moth, including 14 pheromone receptors, and found that CpomOR2a and CpomOR5 responded differently to codlemone acetate. This discovery improves the understanding of pheromone communication in codling moths and can aid in the development of pest management strategies.

Summary: Proeulia auraria is a native pest insect in Chilean fruit orchards, and through the use of synthetic pheromones, mating disruption has been shown to be an effective control method. Further development of commercial products and control strategies are needed to manage this pest.

Summary: This study investigates the characteristics and evolution of the control region (CR) in Tortricidae, a type of moth. Through mitochondrial genome analysis, the researchers found that the CR sequences in Tortricidae exhibit high structural diversity, indicating the plasticity of the mitochondrial DNA molecule in this insect group.

Summary: In this study, 60 candidate odorant receptors, including eight pheromone receptors, were identified by antennal transcriptome analysis. It was found that GmolOR2 responds to the main sex pheromones Z8-12:OAc and E8-12:OAc, and knockdown of GmolOR2 significantly reduces the males' sensitivity to the main pheromones.

Summary: The Adoxophyes tea tortrix is a group of leaf rollers that cause economic losses on tea and apple crops. The taxonomic ambiguity of the Adoxophyes orana complex has persisted due to vague diagnostic characters. This study examines the differences in the complex to improve species identification, determine genetic variations, and develop control strategies. The results reveal the genetic divergence within the complex, suggesting the need for taxonomic revision and the importance of managing the complex in East Asia.

Summary: Studies evaluated the effectiveness of different multi-component lures for codling moth in Italy and the USA, revealing significant geographical differences in trap captures. The PVC lure without sex pheromone performed best in the USA, while lure effectiveness was similar in Italy for both apple and pear crops. Further comparisons are needed in other production regions and in walnut to fully understand the implications of 'female removal' strategies for managing codling moth.

Summary: Environmental pollution is identified as a major factor in the rapid decline of insect populations. However, in this study, while the population density of the studied moth decreased significantly, no visible morphological signs of stress were found, indicating that insect populations can decline without showing obvious signs of stress.

Summary: Paralobesia viteana, the grape berry moth, exhibits regional variation in male response to sex pheromone-baited monitoring traps in Michigan vineyards. Despite differences in captures, Y-tube tests and field experiments indicated that male moths from different populations responded similarly to pheromone blends. This suggests that factors other than pheromone-mediated behavioral responses may be influencing the regional differences in trap captures.

Summary: This study is the first morphological analysis of the male hindwing costal roll in tortricid moths, specifically focusing on the subtribe Cochylina. The research reveals the structure and taxon-dependent traits of this composite organ, and investigates the phylogenetic stability and possible habitat-sharing influences on wing male scent organs.

Summary: This study investigated the genetic variation in seven populations of A. crassicauda from Saudi Arabia, revealing the presence of three distinct lineages and supporting the existence of two distinct populations, possibly indicating a putative different species. Further morphological studies may uncover undiscovered and cryptic species in the region.

Summary: The study found that the sex pheromone components of Conogethes punctiferalis can enhance the attractiveness of Grapholita molesta, potentially improving mass trapping, population monitoring, and mating disruption of the moths.

Summary: This study identified the sex pheromone components of the tea tortrix Archips strojny, with (Z)-11-tetradecenyl acetate (Z11-14:Ac) as the major attractant and (Z)-11-tetradecenyl alcohol (Z11-14:OH) as a potential antagonist. The results suggest that lures baited with 1 mg of Z11-14:Ac could be used as an efficient monitoring or mass trapping tool for pest management in Chinese tea plantations, and Z11-14:Ac may have broader applications in developing mating disruption techniques for multiple leafroller pests.
