Desert locusts, notorious for their ruinous impact on agriculture, threaten over 20% of Earth's landmass, prompting billions in losses and global food scarcity concerns. With billions of these locusts invading agrarian lands, this is no longer a thing of the past. Recent invasions, such as those in India, where losses reached US$ 3 billion in 2019-20 alone, underscore the urgency of action.

Insects represent most of terrestrial animal biodiversity, and multiple reports suggest that their populations are declining globally due to anthropogenic impacts. Yet, a high proportion of insect species remain undescribed and limited data on their population dynamics hamper insect conservation efforts. This is particularly critical in tropical biodiversity hotspots such as Southeast Asia.

Plant-microbe associations are ubiquitous, but parsing contributions of dispersal, host filtering, competition and temperature on microbial community composition is challenging. Floral nectar-inhabiting microbes, which can influence flowering plant health and pollination, offer a tractable system to disentangle community assembly processes. We inoculated a synthetic community of yeasts and bacteria into nectars of 31 plant species while excluding pollinators.

Mating in this species occurs in swarms characterised by male scramble competition and female choice. These mating swarms have a male-biased operational sex ratio, which is expected to generate intense competition among males for mating opportunities.

Ordinary differential equation models such as the classical SIR model are widely used in epidemiology to study and predict infectious disease dynamics. However, these models typically assume that populations are homogeneously mixed, ignoring possible variations in disease prevalence due to spatial heterogeneity. To address this issue, reaction-diffusion models have been proposed as an alternative approach to modeling spatially continuous populations in which individuals move in a diffusive manner.

This study aimed to describe the morphological features and microstructure of the upper, lower, and third eyelids of the black-winged kite, Elanus caeruleus, and to characterize the organized lymphoid follicles and lymphocytes in the eyelid mucosa. Additionally, it aimed to illustrate the importance of the eye adnexa in the eye's immune protection. The upper, lower, and third eyelids display varying morphological differences that seem to be closely linked to the birds' way of life, indicating adjustments to their environment and eating behaviors.

Vector-borne diseases pose a major worldwide health concern, impacting more than 1 billion people globally. Among various blood-feeding arthropods, mosquitoes stand out as the primary carriers of diseases significant in both medical and veterinary fields. Hence, comprehending their distinct role fulfilled by different mosquito types is crucial for efficiently addressing and enhancing control measures against mosquito-transmitted diseases.

Dengue is an increasing threat to individuals living in or visiting endemic countries. Effective vaccines have become available, but their use in travelers is typically only recommended to individuals with documented prior infection. We present a fatal case of severe dengue in an unvaccinated traveler without known prior dengue virus infection but longitudinal serologic and molecular evidence for secondary infection.

Background: The distribution of hosts and parasitoids across patches is a key factor determining the dynamics of host-parasitoid populations. To connect behavioral rules with population dynamics, it is essential to comprehend how individual-level dispersal behavior influences the distribution of individuals. Typically, a simple deterministic model has been used to describe this connection.

Triticum mosaic virus (TriMV; Poacevirus tritici) is the founding member of the genus Poacevirus within the family Potyviridae. TriMV is one of the components of the wheat streak mosaic disease (WSMD) complex, an economically significant wheat disease in the Great Plains region of the USA. TriMV contains a single-stranded positive-sense RNA genome of 10,266 nts with an unusually long 5'-nontranslated region of 739 nts.

The bagrada bug, Bagrada hilaris (Burmeister), is an emerging agricultural pest in the Americas, threatening agricultural production in the southwestern United States, Mexico and Chile, as well as in the Old World (including Africa, South Asia and, more recently, Mediterranean areas of Europe). Substantive transcriptomic sequence resources for this damaging species would be beneficial towards understanding its capacity for developing insecticide resistance, identifying viruses that may be present throughout its population and identifying genes differentially expressed across life stages that could be exploited for biomolecular pesticide formulations.

The nocturnal behaviour and reproduction patterns of Sarcophagidae species during the scotophase are largely unexplored for species in the Neotropical region. The aim of this study was to assess the light regimes under which females of Peckia (Peckia) chrysostoma (Wiedemann, 1830) and Peckia (Sarcodexia) lambens (Wiedemann, 1830) would larviposit and understand how these variables influence intrauterine development in these flies.

Medicinal plants serve as vital resources for preventing and treating diseases, with their flowers, fruits, leaves, roots, or entire plants being utilized in the pharmaceutical industry or as direct therapeutic agents. During our investigation of microfungi associated with medicinal plants in Guizhou and Sichuan Provinces, China, several asexual and sexual fungal morphs were collected. Multi-locus phylogenetic analysis based on combined ITS, LSU, SSU and datasets revealed that these taxa are related to the family Dictyosporiaceae.

The interaction between plants and microorganisms plays a major role in plant growth promotion and disease management. While most microorganisms directly influence plant health, some indirectly support growth through pest and disease suppression. Endophytic entomopathogenic fungi are diverse, easily localized, and have long-lasting effects on insect pests.

Twenty years ago, it was difficult to imagine the use of nucleic acids in plant protection as insecticides, but today it is a reality. New technologies often work inefficiently and are very expensive; however, qualitative changes occur during their development, making them more accessible and work effectively. Invented in 2008, contact oligonucleotide insecticides (olinscides, or DNA insecticides) based on the CUAD (contact unmodified antisense DNA) platform have been substantially improved and rethought.
