Potato cyst nematodes (PCN), such as Globodera rostochiensis and pallida, are quarantine restricted pests of potato causing major yield financial losses to farmers. G. was first reported from Kenya's key growing area in 2015. We sought determine the diversity, prevalence distribution PCN species across country by conducting a country-wide survey between 2016 2018, which included more focused, follow-up assessment three counties. A total 1,348 soil samples were collected 20 Information...
Potato production faces major challenges from inadequate soil fertility, and nematode infestation, yet synthetic fertilizers nematicides are costly harmful to the environment. This study explored potential of chitin-fortified black soldier fly-composted organic fertilizer (BSFCOF) as a multipurpose amendment for enhancing potato yield suppressing cyst nematodes (PCN). The BSFCOF was applied at rate equivalent 150 kg N ha
Root-knot nematodes ( Meloidogyne spp.) are serious pests of most food crops, causing up to 100% yield loss. Nevertheless, commercial nematicides costly and harmful the environment. While nematicidal potential crustacean synthetic chitin has been demonstrated globally, research on insect-derived for nematode control received limited attention. Here, seven chitin-fortified black soldier fly frass fertilizer extracts (chFE) were assessed their suppressiveness incognita impacts spinach growth...
Summary The root-burrowing nematode, Radopholus similis , is reputedly the most damaging nematode pest of banana and responsible for major production losses. In this study, endophytic potential 13 fungal isolates was assessed management R. in East African Highland bananas (‘Ng’ombe’). All successfully colonised tissue-cultured roots, with from Trichoderma Fusarium Hypocrea producing highest (⩾49.1%) Beauveria lowest (⩽14.4%) colonisation. endophytes T. asperellum (ICIPE 700) H. lixii 697)...
Potato production is hindered by soil degradation and nematode infestation. Mineral fertilizers synthetic nematicides are costly cause negative impacts on humans the environment, while organic less effective for health management. This study demonstrates contribution of black soldier fly frass fertilizer (BSFFF) in suppression potato productivity when compared to commercial mineral fertilizer, (SAFI), nematicide. The on-farm experiments consisted eight treatments: BSFFF, SAFI,...
A survey of nematodes associated with terrestrial slugs was conducted for the first time in Norway. total 611 were collected from 32 sample sites. Slugs identified by means morphological examination, dissection genitalia and molecular analysis using mitochondrial DNA. Twelve slug species identified, representing four different families. Internal identified sequencing 18S rRNA gene. Of sites studied, 62.5% found to be positive nematode parasites, 18.7% all discovered being infected. Five this...
The banana weevil (Cosmopolites sordidus) and the burrowing nematode Radopholus similis represent two of most important pests bananas. Previously, colonization plants by non-pathogenic Fusarium oxysporum (isolate V5w2) entomopathogenic Beauveria bassiana WA) have been shown to increase host resistance various diseases. However, there is limited data on how combined inoculation these isolates would affect field performance In this study, fungal endophytes were inoculated separately in...
Abstract Invasive alien species (IAS) rank among the most significant drivers of extinction and ecosystem degradation resulting in impacts on socio-economic development. The recent exponential spread IAS Africa is attributed to poor border biosecurity due porous borders that have failed prevent initial introductions. In addition, countries lack adequate information about potential invasions limited capacity reduce risk invasions. Horizon scanning an approach prioritises risks through rapid...
Entomopathogenic nematodes are commercially available for inundative biological control of many insects, including the black vine weevil Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae). Currently, there is a lack commercial application tests in field‐grown crops comparing efficacy different species entomopathogenic nematodes. Field trials were carried out under growing conditions Ireland and Norway to evaluate two nematode on market Heterorhabditis megidis Steinernema kraussei. was...
A new species of entomopathogenic nematode, Steinernema pwaniensis n. sp., belonging to the glaseri group, is described from Tanzania. The infective juveniles S. sp. are characterized by a body length 978 μm (808-1131), distance anterior end excretory pore 86 (80-95) and tail 87 (75-95). ratios a, c E% substantially lower than those all other African 'glaseri' group members. first-generation males can be distinguished large spicule 92 (80-97) absence caudal mucron, while second-generation...
Coffee is an important commodity for Kenya, where production steadily declining, despite a global rise in demand. Of the various constraints affecting production, plant-parasitic nematodes are significant, but often overlooked, threat. As perennial crop, treating plantations once infected with becomes difficult. The current study evaluated drenching application of two biocontrol agents, Trichoderma asperellum and Purpureocillium lilacinum, their nematode control efficacy, as well impact on...
Norwegian meadows, including those for silage production, are recently found heavily invaded by the slug Arion vulgaris in exposed areas. As a consequence, large numbers of slugs might contaminate grass and cause possible threat to animal feed quality safety. It is well known that contaminated mammalian or avian carcasses can lead severe outbreaks botulism among livestock. Invertebrates, especially fly-larvae (Diptera), considered important transfer Clostridium botulinum type C its toxins...
Plant-parasitic nematodes, particularly root-knot nematodes (RKN: Meloidogyne spp.) and cyst (CN: Globodera Heterodera cause severe yield reduction in most cultivated crops are of high economic importance. African nightshade (Solanum spinach (Amaranthus important indigenous vegetables (AIV) rich sources nutrition income. However, their host status to plant-parasitic remains largely speculative. Therefore, a survey was conducted which revealed that S. villosum exhibited root galling, whereas...
The invasive slug Arion vulgaris (Gastropoda: Arionidae) is an agricultural pest and serious nuisance in gardens of Central Northern Europe. To investigate if the success A.vulgaris Norway can be attributed to a release from parasites, we compared prevalence parasite load nematodes trematodes A. that three native gastropod species, circumscriptus, fasciatus Arianta arbustorum, SE Norway. We found have highest both groups (49% nematodes, 76% trematodes), which does not support hypothesis, but...
Summary A new species of Phasmarhabditis was isolated from the slug, Polytoxon robustum , Nairobi, Kenya. The nematode identified using morphological, morphometric, molecular and phylogenetic analyses. kenyaensis n. sp. is characterised by an infective juvenile with longest body length in genus, measuring 1232 (1107-1336) μ m, presence males a bursa bearing nine bilateral pairs genital bursal papillae one pair papilliform phasmids flanking tail, cephalate paired spicules, arc 71 (57-81) as...
