Abstract

The tolerance of Ceraeochrysa cubana (Hagen) pupae and eggs to 11 insecticides was evaluated under laboratory conditions, based on lethal and sublethal effects. Eggs at three ages (≤24-h-old, 48- to 72-h-old, and 96- to 120-h-old) and pupae at ≤48-h-old were used. All the insecticides were considered harmless when applied at the pupal stage. Phosmet and pyriproxyfen insecticides were considered harmless to eggs irrespective of the age. Esfenvalerate was harmless to eggs at the ages of ≤24-h-old and 48- to 72-h-old. Imidacloprid SC and azadirachtin were harmless to eggs at ages of 48- to 72-h-old and 96- to 120-h-old, and thiamethoxam was only harmless to eggs at 96- to 120-h-old of age. In contrast, chlorpyrifos and malathion were harmful to eggs at the age of 96- to 120-h-old, and imidacloprid WG was slightly harmful to the three egg ages evaluated. Lambda-cyhalothrin + chlorantraniliprole and lambda-cyhalothrin + thiamethoxam were slightly and/or moderately harmful to all egg ages evaluated. Based on the life table parameters, the insecticides thiamethoxam, imidacloprid SC, phosmet, pyriproxyfen, and azadirachtin did not affect the net rate of reproduction (Ro) of C. cubana. Lambda-cyhalothrin + chlorantraniliprole decreased ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
