Assessing parasitism and suitability of three Trichogramma parasitoids Tuta (=Phthorimaea) absoluta (Meyrick) based on parasitoid and host ages Crop Prot. (IF 2.5) Pub Date : 2024-12-26 Zheng-Xiong Jiang, Shun-Wen Zhou, He-Min Yi, Ying Sun, Jin-Long Zhang, Guo-Hua Chen, Lu-Yi Du, Xiao-Ming Zhang
As a major invasive pest, Tuta (=Phthorimaea) absoluta (Lepidoptera: Gelechiidae) poses a substantial threat to tomato production. The use of egg parasitoids from the family Trichogrammatidae (Hymenoptera) has been identified as a potential biological option for controlling T. absoluta. Furthermore, these parasitoids demonstrate effectiveness in parasitizing and managing pests in outdoor settings.

Reproductive and detoxifying responses of Panonychus citri (Acari: Tetranychidae) to sulfoxaflor stress Crop Prot. (IF 2.5) Pub Date : 2024-12-25 Tianrong Xin, Xinyan Kong, Chenyu Jiang, Zhenzhen Li, Zhiwen Zou, Bin Xia
Panonychus citri, is a destructive pest in citrus orchards. The diversity of pests in citrus orchards leads to the improper pesticides application, and induced resistance may be an alternative mechanism for pest resurgence. In the present study, the acute toxicity of sulfoxaflor against P. citri adult females in leaf-dipping exposure experiment was determined at 24 h. Furthermore, the effects of sublethal

Identification and characterization of Colletotrichum camelliae, the causal agent of leaf spot of Polygonatum odoratum in China Crop Prot. (IF 2.5) Pub Date : 2024-12-23 Rui Zhang, Yiyi Feng, Chun Wu, Ke He, Shaming Fu, Cheng Li
Polygonatum odoratum (Mill.) Druce has been widely used in traditional Chinese medicines owing to its renown antioxidant, anticancer, and antidiabetic properties. During surveys conducted in the Zhijin County, Bijie City, Guizhou Province in China, prominent yellow-brown spots were observed on the leaves of P. odoratum. These spots eventually led to the death of the entire plant as they expanded, thus

House sparrow damage to peppers in greenhouses can be decreased by reducing access Crop Prot. (IF 2.5) Pub Date : 2024-12-19 Rubén Tarifa, Jorge Garrido-Bautista, Manuel Soto-Cárdenas, José A. Hódar, Mariano Paracuellos
Greenhouses are one of the most intensified agricultural production systems and where the impact of insect pests has been studied the most, yet there is little information on bird pests affecting crops grown under plastic. To uncover potential conflicts between birds and farmers in southeast Spain, where the highest concentration of greenhouses in Global North is found, we surveyed local farmers to

Diaporthe hispaniae causes leaf black spot disease of kiwi crop in Guizhou Province, China Crop Prot. (IF 2.5) Pub Date : 2024-12-19 Hong Tan, Zhibo Zhao, Youhua Long, Rong Fan
Kiwi is an important commercial fruit crop in China. Leaf spot diseases of kiwi caused by fungal pathogens seriously affect the growth of the fruit tree. In 2023, large areas of kiwi leaves suffered by black spot disease were observed in an orchard in Guizhou Province, China. A total of 230 leaves of twenty-five kiwi trees were randomly investigated, and the incidence of leaves with black spot symptoms
