Differential insecticide resistance in (Hemiptera: Aleyrodidae) field populations in the Punjab Province of Pakistan.

The cotton whitefly (Gennadius) (Hemiptera: Aleyrodidae) has a propensity for developing high-level resistance to insecticides. Management of in cotton grown in Pakistan depends on insecticide use, resistance monitoring has become essential to minimize the development of resistance. In this study, resistance was monitored in adult whiteflies collected from cotton fields in the Bahawalpur, Faisalabad, Lodhran, Multan, and Vehari districts of the Punjab Province, Pakistan during 2017, 2018, and 2019.

Residual Efficacy of Novaluron Applied on Concrete, Metal, and Wood for the Control of Stored Product Coleopteran Pests.

The residual efficacy of novaluron on concrete, metal and wood was evaluated against last-instar larvae of (L.), (Herbst), and Everts. The larvae and food provided for survival were exposed to surfaces pretreated at rates of 0.

Diffusion-weighted MR neurography of median and ulnar nerves in the wrist and palm.

Objectives: To investigate the feasibility of diffusion-weighted magnetic resonance neurography (DW-MRN) in the visualisation of extremity nerves in the wrist and palm.

Methods: Thirty-two volunteers and 21 patients underwent imaging of the wrist and palm on a 3-T MR scanner. In all subjects, two radiologists evaluated the image quality on DW-MRN using a four-point grading scale.
