RNA interference (RNAi) can be used for the protection against agricultural pests through the silencing of genes required for pest fitness. To assess the potential of RNAi approaches in the two-spotted spider mite, Tetranychus urticae, we compared 5 methods for the delivery of double-stranded RNA (dsRNA). These methods include mite feeding on either (i) leaves floating on a dsRNA solution, (ii)...

BACKGROUND The most effective measure in house dust mite antigen reduction is mattress encasing with an impermeable membrane. A reduction in encasing costs will help increase patients' compliance in mite antigen avoidance. OBJECTIVE To investigate the effectiveness of partial mattress encasing with a nylon sheet produced in Thailand on the reduction of group I mite antigens from beddings. M...

The ectoparasitic mite Varroa jacobsoni Oud. presently poses one of the most serious problems faced by keepers of honeybees Apis mellifera L. To help understand why the mite has become such a serious problem a population dynamics model using recently published data has been constructed. The simulation model has been built by linking together various aspects of the mites’ biology using computer ...

the effect of fenpyroximate on life table parameters of two-spotted spider mite tetranychus urticae koch was evaluated under laboratory conditions (25±20c, 60±5% rh and 16:8 l:d). data were analyzed on the basis of age-stage, two-sex life table theory. the estimated value of lc50 for t. urticae was found to be 380 ml/l. durations of total preadult stage and preoviposition period in t. urticae t...

Numerous lab and field studies have reported the potential of soil predatory mites for biological control plant-parasitic nematodes arthropods pests. Most these utilized biocontrol agents in augmentative releases, essentially controlling pest with released predators. While this may be a valid approach, we hypothesize that conservation mite predators available, suitable, accessible free-living a...

The article presents the results of studying black currant varieties collection Kokinsky control station FSBSI FRC for Horticulture (Bryansk region) winter hardiness, resistance to Sphaerotheca, and gall mite in order create new initial forms based on selected genotypes, characterized by a high level adaptation their inclusion breeding work improve crop assortment. best combinations crosses (Ga...

Aims: In order to assess the efficacy of several biorational techniques against brinjal mite, Tetranychus urticae Koch.
 Study Design: The study used a single component Randomized Complete Block Design (RCBD) with three replications.
 Place and Duration Study: experiment was conducted in central farm Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from October 2021 February 2...

few biomarkers that can predict the clinical response to allergen immunotherapy (ait) have been identified. the aim of the present study was to investigate parameters that could be used “in predicting the clinical response to ait” in children with asthma caused by house dust mites. we evaluated 107 children with mild persistent asthma who were sensitised only to mite aeroallergens. the study gr...

Integrated pest management (IPM) tactics may effectively control focal pests, but it is also important to test the compatibility of different tactics, and consider non-target organisms. We investigated the effects of a neonicotinoid seed treatment and Rag resistance genes used for soybean aphid (Aphis glycines Matsumura) control on reproduction of a non-target herbivore (twospotted spider mite,...
