Summary: The study revealed that resistance of Spodoptera frugiperda to emamectin benzoate is polygenic and shows incomplete dominant inheritance. Low cross-resistance was detected between emamectin benzoate and other insecticides. The synergists did not have a significant effect on the Ben-R strain, indicating a minor role of metabolic resistance in resistance evolution.

Summary: This study aimed to develop specific microsatellite markers for the predatory mite Phytoseiulus macropilis, resulting in the discovery of seven polymorphic loci that can be used for genetic and molecular studies. These markers are the first developed for P. macropilis and show high transferability to closely related species, facilitating further research in population genetics and molecular biology.

Summary: The study found that the Bt-resistant Brazilian strain Sf_Des has medium resistance to deltamethrin and chlorpyrifos, high cross-resistance to Cry1 toxins but high susceptibility to Vip3A. In comparison to the susceptible strain Sf_Bra, Sf_Des exhibited up to 19-fold increased cytochrome P450 activity and upregulation of multiple P450 transcripts. Gene Ontology analysis categorized most differentially expressed genes into oxidation-reduction and metabolic processes.

Summary: Despite the implementation of environmentally compatible integrated control strategies, such as mating disruption and attract-kill strategies, the management of codling moth still heavily relies on insecticides. There have been varying levels of insecticide resistance towards different types of insecticides in codling moth populations worldwide, involving both metabolic and target-site mechanisms.

Summary: Traditional acaricides have limited impact on Phytoseiulus persimilis, while botanical acaricides show low selectivity that can be improved by limiting exposure routes. Molecular stress responses were limited, but target-site mutations were identified, explaining physiological selectivity of acaricides to predatory mites.

Summary: This study monitored the resistance of field strains of Spodoptera littoralis to six insecticides in three Egyptian Governorates over three consecutive seasons. The results showed significant differences in LC50 values and resistance ratios among the field strains. Some field strains exhibited low resistance to certain insecticides, while no resistance developed to others. The activity levels of detoxification enzymes and the target site also differed among the field strains.

Summary: This study investigated the resistance of the green peach aphid to 13 insecticides in a cabbage field in China. The results showed that the aphids had high resistance to beta-cypermethrin and imidacloprid, and this is the first report of resistance to sulfoxaflor, flupyradifurone, pymetrozine, spirotetramat, flonicamid, and broflanilide in China. The resistance is associated with target-site mutations and overexpression of enzymes. The findings provide guidance for the rational use of insecticides to delay resistance development.

Summary: The study found that the plant defense triggered by different species of phytoseiids is species-specific, dependent on plant genotype, and may be triggered by non-feeding activities. Tetranychus urticae tend to avoid better protected plants with stronger defense mechanisms. This highlights the importance of further research on the impact of different predatory mites on plant defense responses and prey behavior.

Summary: Monitoring of acaricide resistance in phytophagous mites is crucial for effective pest management. A study conducted in citrus orchards in Cukurova region of Turkey found that certain populations of citrus red mites have developed resistance to commonly used acaricides. It is suggested that rotating acaricides with different modes of action is fundamental to prevent potential resistance problems.

Summary: The two-spotted spider mite is an important pest in apple orchards that quickly develops resistance to acaricides. Monitoring the susceptibility levels of these mites to acaricides is crucial for effective chemical control. This study determined the resistance rates of different populations of the two-spotted spider mite collected from apple orchards in Isparta province against three acaricides. Results showed that some populations developed resistance to the tested acaricides, including cross-resistance to multiple substances.

Summary: This article introduces a generic Bayesian network model called PRReSTo, which estimates likely infestation rates of host items in consignments. PRReSTo takes into account the vulnerability of host items to pest infestation, the abundance of pests to which host items are exposed, and the effects of risk-reducing measures. PRReSTo can be used to evaluate the effectiveness and acceptability of risk reduction measures in different pest-host systems.

Summary: Colletotrichum and Alternaria species have become emerging fungal pathogens causing severe economic losses in citrus orchards in the Mediterranean area. The use of copper-based antimicrobials for disease management is increasingly problematic, and research for alternative formulations is encouraged. This study tested copper-alternative products on citrus orchards and found that they significantly reduced disease incidence and severity, often showing comparable or better efficacy than copper. The good efficacy of these products suggests their potential for sustainable and large-scale use in integrated and organic citriculture.

Summary: This study updated the economic thresholds for Lygus spp., a major insect pest of canola in Canada, by integrating a large data set collected over 23 years. The results revealed that the economic injury level for Lygus was around 9-23 insects per 10 sweeps, while spraying a foliar insecticide was only necessary when Lygus catches exceeded 30 insects per 10 sweeps. Additionally, analysis of Precision Yield Data showed that at low abundances (under 17 insects per 10 sweeps), Lygus may potentially stimulate canola yield and do not require control action.

Summary: A novel methodology was proposed to analyze water-sensitive papers (WSPs) for evaluating spray quality. The segmentation of overlapping droplets based on concave point detection and ellipse fitting achieved high accuracy. A linear relationship between droplet density and coverage was observed, and simulated WSPs were generated for high coverage estimation. This approach allows for more accurate spray quality indicators from WSP collectors.
