Oryctes rhinoceros is an important pest of oil palm. This study aimed to obtain the best ability several compost organic materials containing B. bassiana for controlling O. larvae, in control various instars and concentration Beauveria O larvae. rhinoceros. Three stages research experiment were: 1) testing at 75 gl-1 concentration, using a completely randomized design (CRD), Experiment 2 test w...

This study presents the possibility of killing almost all microorganisms such as fungi, bacteria, spore forms, and viruses by sterilization process. European foulbrood (EFB) American (AFB) is a highly infectious bacterial honeybee disease caused Melissococcus plutonius Paenibacillus larvae, respectively. Removal spores from contaminated beehives critical factor in controlling EFB AFB. The purpo...

Abstract. Sari JMP, Herlinda S, Suwandi Elfita. 2023. Effect of Beauveria bassiana and Metarhizium anisopliae on the growth Spodoptera frugiperda by seed inoculation. Biodiversitas 24: 2350-2357. J.E.Smith 1797 larvae are more difficult to control because they hide in leaf sheaths. Therefore, it is necessary use endophytic entomopathogenic fungi S. larva. The aim this research was observe effec...

BACKGROUND Inhalation allergies, caused by allergens from various kinds of pollen, house dust mites, animal epithelium, and mould fungi, are strongly increasing in frequency. In 2.6% of the cases the allergen source remains unidentified. The present paper describes a so far unknown inhalation allergy which was observed in the case of a patient working with hives. METHODS AND RESULTS The aller...

The guts of beetle larvae constitute a complex system where relationships among fungi, bacteria, and the insect host occur. In this study, we collected larvae of five families of wood-feeding Coleoptera in tropical forests of Costa Rica, isolated fungi and bacteria from their intestinal tracts, and determined the presence of five different pathways for lignocellulolytic activity. The fungal iso...

The entomopathogenic Fungi comprise a wide range of ecologically diverse species. This group of parasites can be found distributed among all fungal phyla and as well as among the ecologically similar but phylogenetically distinct Oomycetes or water molds, that belong to a different kingdom (Stramenopila). As a group, the entomopathogenic fungi and water molds parasitize a wide range of insect h...

Recent declines in bee populations coupled with advances in DNA-sequencing technology have sparked a renaissance in studies of bee-associated microbes. Megachile rotundata is an important field crop pollinator, but is stricken by chalkbrood, a disease caused by the fungus Ascosphaera aggregata. To test the hypothesis that some gut microbes directly or indirectly affect the growth of others, we ...

Pine tree death caused by pine wood nematode (PWN) involves phoretic relationships between PWN and its vector Japanese pine sawyer beetle (JPS). In an effort to understand the diversity of fungi involved in PWN life cycle, a total of 176 fungal isolates were collected from PWNs, adults and larvae of JPS, PWN-diseased Japanese black pine that was cut down in 2005 at Jinju, Korea. Based on micros...

The larvae and less frequently the pupae of Plutella xylostella (L) are sometimes attacked naturally by pathogens, particularly two fungi of the family Entomophthoraceae, Erynia blunckii and Zoophthora radicans. Other pathogens recorded include one other entomophthoraceous fungus, a granulosis virus, one or possibly two nucleopolyhedrosis viruses and Bacillus thuringiensis var kurstaki. In the ...
