(phylum Ascomycota, family Sclerotiniaceae) causes fruit disease 'mummy berry' on berry crops and responsible for yield losses and quality of fruits. We reported mummy berry disease of black huckleberry (Vaccinium membranaceum) first time in British Columbia, Canada. We have performed sequencing and genome assembly of from infected fruits of huckleberry. The resulting genome was 33.8 Mbp in size and consisted of 2,437 scaffolds with an N50 of 33,816 bp. To our best knowledge, this is the first report of resource announcement of whole genome sequence of mummy berry pathogen () infecting black huckleberry. The genome resource will be valuable for future studies to understand the genomic structure of pathogen, and mechanisms associated with black huckleberry- interactions.

Advances in molecular ecology can overcome many challenges in understanding host-parasitoid interactions. Genetic characterization of the key-players in systems helps to confirm species and identify trophic linkages essential for ecological service delivery by biological control agents; however, relatively few agroecosystems have been explored using this approach. Pecan production consists of a large tree perennial system containing an assortment of seasonal pests and natural enemies.

Introduction: Mummy berry is a serious disease that may result in up to 70 percent of yield loss for lowbush blueberries. Practical mummy berry disease detection, stage classification and severity estimation remain great challenges for computer vision-based approaches because images taken in lowbush blueberry fields are usually a mixture of different plant parts (leaves, bud, flowers and fruits) with a very complex background. Specifically, typical problems hindering this effort included data scarcity due to high manual labelling cost, tiny and low contrast disease features interfered and occluded by healthy plant parts, and over-complicated deep neural networks which made deployment of a predictive system difficult.

The green peach aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae), is a major pest of brassica plants, with the ability to transmit > 100 viruses. Although the adoption of Integrated Pest Management is increasing, chemical treatment remains the predominant method used to control M. persicae globally.

Risk assessments of chemical pesticides toward natural enemies are crucial for ensuring sustainable grapevine-integrated pest management. In this context, laboratory experiments were conducted to evaluate the toxicity of four insecticides (lambda-cyhalothrin, flupyradifurone, acetamiprid, and cyantraniliprole) and one fungicide (spiroxamine) commonly applied in German (European) vineyards on the pupae and adults of both , a parasitoid of the vine mealybug , and , a parasitoid of the European grapevine moth, . The tested pesticides did not significantly affect the development of the pupal stage inside mealybug mummies or the emergence of the parasitoid .
