Exposure risks and ineffectiveness of total release foggers (TRFs) used for cockroach control in residential settings

BMC Public Health, 2019
Background The German cockroach, Blattella germanica, is one of the most challenging pests to eradicate from indoor environments. Professional pest control is often prohibitively expensive, prompting low-income residents to turn to over-the-counter ...

Laboratory, simulated‐use, and field evaluation of non‐insecticidal consumer products for indoor pest management: a freeze‐spray aerosol, light traps, and an ‘insect repellent’ lamp

Pest Management Science, EarlyView.
Control efficacy of three types of non‐insecticidal consumer products were examined in laboratory, simulated‐use, and field conditions. Freeze spray and ‘repellent lamp’ showed limited efficacy, whereas various results in attraction in light trap were reported.

Identification of Novel Allergenic Components from German Cockroach Fecal Extract by a Proteomic Approach

, 2013
BACKGROUND: Cockroaches produce potent allergens, and cockroach feces are known to be especially rich in allergens. In this study, we analyze the allergenic components from cockroach feces and evaluate allergenicity of recombinant α-amylase identified ...

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Efficacy of knockdown insecticide based on Permot (Passiflora foetida L.) leaf extract against mortality of German cockroach (Blattella germanica L.) [PDF]

, 2021
Chemical insecticides have a detrimental effect on not only the target species, but also on non-target species and the environment. Transfluthrin is a pyrethroid class II insecticide that is considered to be safe for humans. However, repeated use over an

Tropomyosin-based cross-reactivity and asymptomatic shellfish sensitization in patients with perennial allergy

Frontiers in Allergy
BackgroundMite, cockroach, and shellfish (crab, clam, and shrimp) proteins share allergenic epitopes. The determination of specific IgE (sIgE) against cockroach (Blattella germanica, relevant in asthma) and shellfish allergens (relevant in food allergy ...

Resistance development characteristics of reared German cockroach (Blattodea: Blattellidae) to chlorpyrifos

Scientific Reports, 2021
Understanding the process of resistance development of German cockroach, Blattella germanica (L.), in detail is necessary to potentially delay the development of insecticides resistance by rotation or discontinuation of insecticides at the right time. In

Juvenile hormone and allatostatins in the German cockroach embryo [PDF]

Insect Biochemistry and Molecular Biology, 2010
Levels of juvenile hormone III (JH), FGLamide allatostatin peptides (ASTs), ASTs precursor (preproAST) mRNA and methyl farnesoate epoxidase (CYP15A1) mRNA were measured in embryos of the cockroach Blattella germanica. JH starts to rise just after dorsal closure, reaches maximal levels between 60% and 80% of embryogenesis, and decrease subsequently to ...

Distinct Nasal Microbiome Profiles and Prediction Model for Allergic Rhinitis, Nonallergic Rhinitis, and Healthy Children

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
The alpha and beta diversity of the nasal microbiome differed among children with allergic rhinitis (AR), nonallergic rhinitis (NAR), and healthy controls (HCs). Compared to HC, AR had more Escherichia‐Shigella, Negativicoccus, and Campylobacter, while NAR had more Dolosigranulum and fewer Enterobacteriaceae.

Home foreclosure discounts in auctions without reserve prices

Real Estate Economics, EarlyView.
Abstract This article estimates foreclosure discounts in Cape Town, South Africa, where, until 2019, foreclosure auctions occurred without reserve prices. Using newly constructed data linking sheriff auction notices to the universe of property transactions, rich property characteristics, and municipal service‐request records, I document large ...
