Abstract Inspection of insect sticky paper traps is an essential task for effective integrated pest management (IPM) programme. However, identification and counting the pests stuck on a very cumbersome task. Therefore, efficient approach needed to alleviate problem provide timely information pests. In this research, automatic method multi‐class recognition small‐size greenhouse trap images acquired by wireless imaging devices proposed. The developed algorithm features cascaded that uses...

Nanoparticles and nanotechnology have been applied in agriculture, including for plant nutrition improvement, pest control. Little research has conducted on nano-calcium carbonate protection nutrition. In this study, we compared the effects of colloidal calcium found that treatments were better at increasing content when sprayed Tankan (Citrus tankan) leaves. Field tests California red scale (Aonidiella aurantii) Oriental fruit flies (Bactrocera dorsalis) both showed yielded control rates....

Oriental fruit flies, Bactrocera dorsalis (Hendel), were treated with 10 insecticides, including six organophosphates (naled, trichlorfon, fenitrothion, fenthion, formothion, and malathion), one carbamate (methomyl), three pyrethroids (cyfluthrin, cypermethrin, fenvalerate), by a topical application assay under laboratory conditions. Subparental lines of each generation the same insecticide selected for 30 generations designated as x-r (x, insecticide; r, resistant). The parent colony was...

Holm's method and Hochberg's for multiple testing can be viewed as step-down step-up versions of the Bonferroni test. We show that both are special cases partition testing. The difference is that, while tests each hypothesis using largest order statistic, setting a critical value based on inequality, all statistics, series values Simes' inequality. Geometrically, ‘cuts corners’ off acceptance regions by making assumptions joint distribution test statistics. As expected, use statistics more...

In this study, we assessed the potential for development of resistance to insecticide spinosad in a laboratory colony oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). Resistance was selected by using topical applications spinosad. After eight generations selection, LD50 line 408 times greater compared with that untreated parental colony. This spinosad-resistant did not exhibit cross-resistance 10 other insecticides tested, including six organophosphates (naled,...

Insecticide resistance has recently become a critical concern for control of many insect pest species. Genome sequencing and global quantization gene expression through analysis the transcriptome can provide useful information relevant to this challenging problem. The oriental fruit fly, Bactrocera dorsalis, is one world's most destructive agricultural pests, it been used as target studies genetic mechanisms related insecticide resistance. However, prior study, molecular data available...

Main bottleneck in facilitating integrated pest management (IPM) is the unavailability of reliable and immediate crop damage data. Without sufficient insect plant disease information, farm managers are unable to make proper decisions prevent damage. This work aims present how an system was able drive towards sustainable data-driven IPM.A called Intelligent Integrated Pest Disease Management (I2 PDM) developed. Edge computing devices were developed automatically detect recognize major...

Abstract An investigation into proteins involved in chemosensory perception the melon fly, Bactrocera cucurbitae (Diptera: Tephritidae) is described here using a newly generated transcriptome dataset. The fly major agricultural pest, widely distributed Asia-Pacific region and some parts of Africa. For this study, dataset was RNA extracted from 4-day-old adult specimens fly. assembled annotated via Gene Ontology (GO) analysis. Based on similarity searches to data other species, number protein...

Control of Zeugodacus cucurbitae, a serious agricultural pest worldwide, often includes or is dependent on the use spinosad-based insecticides. This especially case in Hawaii, where GF-120, protein bait containing spinosad as active ingredient, has been key integrated management (IPM) tool against this Tephritid for last two decades. Here, we report resistance to [resistance ratios (RRs) and median lethal concentration (LC

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), ranks as one of the world's most destructive agricultural pests. This pest is also widespread and highly invasive; thus, it a high priority for detection quarantine programs. Although fly adult third-instar larvae can usually be identified distinguished from other species by morphological keys, often difficult or impossible to identify distinguish this tephritids using material stages development. In such...

Pesticide resistance poses many challenges for pest control, particularly destructive pests such as diamondback moths ( Plutella xylostella ). Organophosphates have been used in the field since 1950s, leading to selection resistance-related gene variants and development of new insecticides moth. Identifying actual potential genes involved could offer solutions control. This study established resistant moth strains from two different collections using mevinphos. Two sets transcriptome...

Abstract The potential for populations to become resistant a particular insecticide treatment regimen is major issue all insect pest species. In Hawaii, example, organophosphate (OP)‐based cover sprays have been the chemical most commonly applied against oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), since 1950s. Moreover, bait spray treatments using spinosad were adopted as control tactic in Hawaii area‐wide fly management program beginning year 2000. To determine...

Naled-intoxicated methyl eugenol (ME) is commonly used to control oriental fruit flies, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in Taiwan. However, non-responsiveness ME and pesticide resistance flies may reduce efficacy. In this study, mark-recapture experiments were analyze the effects of naled-intoxicated on field naled-resistant fly strains. was tested field, naled-resistant, susceptible strains pyrosequencing techniques detect frequencies point mutations organophosphate...

Paper-based technologies have been drawing increasing attentions in the biosensor field due to their economical, ecofriendly, and easy-to-fabricate features. In this paper, we present a time-delay valve mechanism automate series of procedures for conducting competitive enzyme-linked immunosorbent assay (ELISA) on paper-based device. The employs controllable valve, which has surfactants dissolve hydrophobic barriers, fluid pathway. valves can regulate liquid sequentially deliver sample flow...

Assessment of the fetal brain volume and blood flow is important in evaluation growth. We used three-dimensional (3D) ultrasound power Doppler to assess index during normal gestation. The relationships these parameters were further analyzed.We assessed total pregnancies using 3D (Voluson 730). bilateral parietal diameter (BPD) plane was measured by a transabdominal probe scan under mode. Then, we quantitatively brain, mean grey area (MG), vascularization (VI), (FI), vascularization-flow...
