Nanomaterials for Plant Disease Diagnosis and Treatment: A Review.

Currently, the excessive use of pesticides has generated environmental pollution and harmful effects on human health. The controlled release of active ingredients through the use of nanomaterials (NMs) appears to reduce human exposure and ecosystem alteration. Although the use of NMs can offer an alternative to traditional methods of disease diagnosis and control, it is necessary to review the current approach to the application of these NMs.

Preliminary Bioactivity Assessment of Species (Stachybotryaceae) Crude Extracts against (Diptera: Culicidae): A First Approach from This Phytopathogenic Fungi.

Mosquitoes, as insect vectors, play a crucial role in transmitting viruses and parasites, leading to millions of human deaths in tropical and subtropical regions worldwide. This study aimed to evaluate the effects of ethanolic extracts of three species within the genus (, , and ) on mosquito larvae to assess the inhibitory effect on growth and development, as well as to determine mortality. We quantify the average lethal concentrations and provide a qualitative characterization of the chemical groups responsible for their potential.

Behavioral report of in response to substrate infestation by and using a tetrahedron olfactometer device.

Calliphoridae are widespread globally and can inhabit a variety of habitats. In this brief report, we assessed the appeal of to resources that were previously inhabited by and , both common carrion colonizers. Two hundred adult male and female (1:1) were released under controlled conditions into clear plastic cages (45 x 45 x 45 cm) with four types of substrates: beef-liver; liver with 100 third-instar larvae of ; (III) liver containing 100 third-instar larvae of L.

Diagnosis and Integrated Management of Fruit Rot in , Caused by .

Fruit rot is the principal phytopathological problem of pipiana pumpkin ( Huber) in the state of Guerrero. The aims of this research were to 1) identify the causal agent of southern blight on pumpkin fruits by morphological, pathogenic, and molecular analysis (ITS1, 5.8S, ITS2); 2) evaluate spp.
