Abstract The fall armyworm ( FAW , Spodoptera frugiperda ) originates from the tropical and sub‐tropical regions of Americas. Recently it was reported for first time in Africa has since spread rapidly across more than 30 countries continent. Chemical pesticides are being promoted used management, but where application practices and/or active ingredients unsafe there is a need to make effective, low‐risk products available. Given that biopesticides such as microbials microbial extracts,...

Understanding the progression of host–pathogen interaction through time by hyperspectral features is vital for tracking yellow rust (Puccinia striiformis) development, one major diseases wheat. However, well-designed are still open issues that impact performance relevant models to nondestructively detect pathological progress wheat rust. The aim this paper (1) propose a novel wavelet-based spectral feature set (WRSFs) uncover rust-related processes; and (2) evaluate robustness proposed WRSFs...

Abstract The fall armyworm (FAW, Spodoptera frugiperda ) has recently spread to many countries in Africa, the Near East, Asia and Pacific. In sub‐Saharan Africa (SSA), more than 300 million people depend on FAW’s preferred host plant, maize, as a staple crop. Hence, of FAW SSA potential negatively affect livelihoods food security. Many farmers have responded by increasing their use synthetic pesticides, but these are not always used safely or effectively. More information sustainable...

The necessity of cold storage for mycoinsecticides poses a logistical challenge in tropical Africa, where maintaining consistent refrigeration is major obstacle. To investigate alternative preservation methods, our study evaluates conidial-based freeze-dried formulations Beauveria bassiana (IMI 389521), Metarhizium acridum 330189), and mycelial-based Hirsutella thompsonii 327488 IMI 391722). Propagules were cryoprotected with lactose, mannitol, raffinose, encapsulated, plastic glass vials....

Using qualitative methods, this study assessed the stakeholders and management processes involved in locust outbreaks China, including factors influencing use of biopesticides. Study findings show that China has an integrated national response protocol, which involves various institutions from all administrative levels government. The process is inherently highly complex but efficient, with multisectoral agencies working closely together to prevent and/or manage outbreaks. In addition, been...

Chemical insecticides are used to protect stored grain from infestation by product insects and mites. In the UK only a limited number of products available for application there concerns about safety, pest resistance environmental impact these conventional pesticides. Biological control offers an alternative use chemical insecticides. The potential biological storage pests in using insect-specific fungus, Beauveria bassiana , treat structure stores, has previously been established. However,...

Fungal formulations are vital for effective biopesticide development. Good help to optimise field efficacy, while poor result in product failure. This study aimed produce a hydrophobicity test that would be appropriate fungal conidia produced commercial quality and determine relative of fungi from four different genera by using laser diffraction. A particle size analyser was used the of: three Metarhizium acridum samples, M. anisopliae, Beauveria bassiana, Trichoderma stromaticum, T....

The larger grain borer, Prostephanus truncatus (Horn) and the maize weevil, Sitophilus zeamais Motschulsky continue to cause tremendous losses stored maize. Research in UK has identified Beauveria bassiana, IMI 389521 as a suitable control agent for storage pests UK. pathogenicity of B. was evaluated against adult P. truncatus, S. Teretrius nigrescens Ghana. Fifty adults each insect species were treated with 0.5 g dry conidia powder this isolate at 8.65 × 108 conidia/g 1 minute mortality...

Fall armyworm (FAW) is a major pest of maize and causes huge losses. Chemical pesticides are the commonly used control strategy among farmers. The efficacy baculoviruses against FAW has been proven; however, farmers may not be able to afford products. use farmer-produced baculovirus mixtures could provide an opportunity for nature-based solution at low cost. This study evaluated potential recycled virus inoculum from larvae treated with commercial (Littovir) management under laboratory field...

Papaya mealybug (PMB), Paracoccus marginatus, native to Mexico and Central America, invaded Kenya in 2016 causing severe yield losses of between 57% 91% £2224/ha household economic annually. A classical biological program for PMB involved the importation Acerophagus papayae, a koinobiont endoparasitoid, from Ghana into quarantine facility at Agricultural Livestock Research Organization, Muguga. Laboratory bioassays were conducted evaluate suitability A. papayae parasitize PMB. Parasitism...

Recent research in Ghana has demonstrated the effectiveness of an isolate B. bassiana, sensu lato (IMI 389521) from U.K. against larger grain borer Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), a major pest stored maize. To determine whether this is effective on immature stages P. truncatus, laboratory study response (egg, larvae and pupae) maize grains to two concentrations (1 × 109 3.16 cfu/kg maize) IMI 389521 formulated with Entostat™ kaolinite was undertaken. Adult...

The production of tomato in Pakistan is affected by Helicoverpa armigera, which causes significant crop loss. Farmers mostly use insecticides to control the pest, but an excessive and indiscriminate these products has resulted environmental health hazards. Trichogramma promoted as alternative bio-control method. This study aimed look at gender-related barriers against uptake farmers Punjab, Sindh, Khyber Pakhtunkhwa provinces Pakistan. Key-informant interviews were conducted with researchers...

The oriental migratory locust is a major crop pest across eastern and south-eastern Asia. Metarhizium anisopliae an effective biopesticide agent used for control, but its performance temperature dependent, thus can be more variable than chemical pesticide performance. To predict the control of locust, we adapted previous temperature-dependent model validated it using field trial data. increase applicability this model, explored use readily available variables, as well our own...

Oedaleus decorus asiaticus (Bei-Bienko, 1941) has been regarded as one of the most dominant locusts in northern grassland, adjacent area agriculture and animal farmland, China. The aims this study were to investigate effects vegetation type on oviposition behavior pest an open field hatching success offspring following year. results showed that did have a significant effect whether any egg pods laid by O. d. asiaticus. Once females eggs, cage number had laid. highest was found Cleistogenes...

Abstract The short- to medium-term viability and growth of Metarhizium anisopliae var. acridum conidia were investigated when combined with six insecticides, at three different concentrations. All the insecticides used in this study suitable for immediate spraying M. except fenitrothion. Fipronil, teflubenzuron, fenitrothion formulations significantly reduced conidial over time. 10% teflubenzuron treatment caused loss relatively quickly 9.9% germination after 28 days. Mycelial was affected...

Oedaleus decorus asiaticus is one of the most harmful locusts in agricultural and pastoral areas China. Plagues this grasshopper can aggravate grassland degradation cause huge damage to livestock industry. Fungal biopesticides are seen as a suitable means controlling grasshoppers locusts. However, efficiency fungal dependent on temperature. Currently, there limited knowledge thermal biology natural habitats. In study, ground temperature measurements were made conjunction with internal body...
