A water-soluble polysaccharide was isolated from the culture filtrate of a fungal strain, Sphaeropsis sp. TNPT116-Cz, as a novel insect chitinase inhibitor. It was purified to chromatographic homogeneity by ethanol precipitation, anion-exchange and gel filtration chromatography. Its molecular weight was estimated to be 16 kDa by gel filtration HPLC. Monosaccharide analysis showed that it contai...

We describe the isolation and characterization of an insect pathogenic bacterium from the entomopathogenic nematode Heterorhabditis indica (Karnataka strain), an isolate from the southern regions of India. The strain has been identified and characterized by phenotypic, biochemical tests and PCR-RFLP analysis of the 16S rRNA gene as Photorhabdus luminescens subsp. akhurstii. The insecticidal tox...

Effects of natural and artificial diets under two rearing methods (group individual) on larval pupal development survivability Spodoptera litura (Fab.) were studied. The survival rate larvae pupae was significantly affected by (P = 0.05), which higher diet when reared individually. Results this study documented the growth index from diet. indices 5.24 1.65 individual group rearing, respectively...

Pyridalyl is a novel synthetic insecticide discovered by Sumitomo Chemical Co. Ltd. and has been developed globally as the trade names, Pleo, or Sumipleo. The compound is highly effective against various pests of Lepidoptera, Thysanoptera, Diptera and certain Acari, including resistant strains that are less susceptible or resistant to existing insecticides. The lepidopterous larvae treated with...

Public awareness of consuming healthy food with minimal pesticide residues has been on the rise. By contrast, farmers still rely synthetic chemical pesticides to control pests. The shift from insecticides botanical or bioinsecticides is quite complex, especially in Indonesia. Farmers must have appropriate technology be independent insecticide. This study aims test effectiveness organic adjuvant...

Sub-districts Kie and Fatumnasi are two sub-districts in mainland West Timor that cultivate local potatoes from Soe. This germplasm needs to be preserved developed diversify non-rice alternative food. One of the main obstacles cultivating is presence pests, but so far there have been no reports pests on potato plants Soe sub-districts, this research done. study aimed at an inventory important a...
