species have commonly been reported as important plant pathogenic fungi with wide host ranges and geographic distributions. With the increase in the number of cryptic species being described, a comprehensive global taxonomic revision of the genus is required. The present study includes 399 isolates from 32 countries.

Competition between mosquito species during the larval phase is a well-established mechanism structuring container mosquito communities, with invasive species often outperforming natives. We assessed the competitive outcome between 2 species that occur on the island of Puerto Rico, the historic invasive Aedes aegypti (L.) and the endemic Aedes mediovittatus (Coquillett) (Diptera: Culicidae).

Control measures rely on pesticides with negative impacts on the environment, natural ecosystems, and human and animal health. In contrast, gene-targeting methods have the potential to specifically target the vector species and/or reduce pathogen transmission.

Background: Insecticide-based malaria vector control has been implemented on the islands of São Tomé and Príncipe (STP) for more than 20 years. During this period malaria incidence was significantly reduced to pre-elimination levels. While cases remained low since 2015, these have significantly increased in the last year, challenging the commitment of the country to achieve malaria elimination by 2025.

Alfalfa (Medicago sativa L.) is a commonly grown forage crop in Oregon and California harvested on 350,000 and 480,000 acres, respectively, in 2023 (USDA-NASS 2023). Forage alfalfa is grown as a perennial crop for about four years in the same field and each season, the crop is cut 3-4 times for hay production.

The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is a polyphagous pest recognized as composed of several cryptic or sibling species. The Middle East-Asia Minor 1 (MEAM1) and the Mediterranean (MED) putative species are invasive and destructive worldwide. The MEAM1 is established throughout the United States, while MED is documented in 27 states.

Little is known about the behaviors of African equatorial rain forest mosquito species and their potential role as sylvatic and bridge-vectors of various pathogens of animal and public health. In 2016 and 2017, the diversity and sources of water supporting immature development of mosquitoes in Talangaye Rainforest (South West Cameroon) before, during and after deforestation were investigated. Mosquito eggs, larvae and pupae were collected from 12 natural, seminatural, and artificial water sources and reared to adults.

Entomopathogenic nematodes (EPNs) of the genera Heterorhabditis and Steinernema represent an alternative for the biological control of insects. The limited half-life of EPNs is still one of the most concerning issues in their commercialization. Lipid peroxidation (LPO) caused by reactive oxygen species (ROS) may be one of the most important causes of loss of infectivity and survival of EPNs when exposed to various physicochemical stress conditions (temperature, pH, hypoxia and osmotic pressure).

Arthropod-borne viruses or arboviruses, including West Nile virus (WNV), dengue virus (DENV), and Zika virus (ZIKV) pose significant threats to public health. It is imperative to develop novel methods to control these mosquito-borne viral infections. We previously showed that insulin/insulin-like growth factor-1 signaling (IIS)-dependent activation of ERK and JAK-STAT signaling has significant antiviral activity in insects and human cells.

Background: Huanglongbing (HLB) is a systemic disease of citrus caused by the bacterial pathogen Candidatus Liberibacter asiaticus (CLas) that limits citrus production worldwide. CLas is an obligate bacterial pathogen that multiplies in citrus trees and in the insect vector, the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. There is no cure for HLB currently and broad-spectrum antibiotics represent one possible therapeutic against disease symptoms.

In this work, with parathion, a typical forbidden organophosphate pesticide as target drug, an enhanced nanobody-driven bioluminescent immunoassay based on the engineered split-nanoluciferase (NanoLuc) was proposed. Concretely, through labeling 11S and β10, two split-NanoLuc units onto the anti-parathion nanobody (Nb) VHH9 and the artificial antigen H1 coupled with carrier protein ovalbumin (H1-OVA) respectively, an NanoLuc Binary Technology (NanoBiT) system was firstly developed in the form of homogeneous immunoassay, in which the luminescence signal was produced by the reassembled NanoLuc after the combination of the 11S-fused VHH9 and β10-labeled H1-OVA. Subsequently, in order to enhance the signal-to-noise (S/N) ratio, a novel strategy of splitting 11S into two smaller subunits Δ11S and β9 was adopted so then an NanoLuc Ternary Technology (NanoTeT) system based on tri-part components of β9-fused VHH9, β10-labeled H1-OVA and Δ11S was successfully established.

A new type of label-free electrochemical immunosensor for the high-sensitivity determination of parathion was developed based on the oriented immobilization of nanobody (VHH9) on a gold nanoparticle-loaded polyvinyl alcohol/citric acid nanofiber membrane-modified electrode. The morphology characterization and assembly process of the modified materials were investigated using scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). Under the optimum conditions, the label-free electrochemical immunosensor for parathion exhibited a linear range of 0.
