Title : Occurrence of Ichthyophthirius multifiliis on snow trout fry (Schizothorax richardsonii) in godawari fish farm, Nepal Material Type: printed text Authors: Rayamajhi, A., Author ; Roy, N.K., Author Pagination: 373-378 p. Languages : English (eng) Keywords: Ichthyophthirius, protozoan parasite, prevalence, occurrence, rainy season Abstract: The protozoan parasite identified as Ichthyophthirius multifiliis Fouquet (1876) was first time noticed on snow trout (Asala) fry (Schizothorax richardsonii) reared in Godawari Fish Farm. The parasitism of I. multifiliis to Asla fish is a new occurrence in Nepal. Site of occurrence of I. multifiliis was observed in wet smear of skin, fin and gills scraping as well as in the underlying musculature of skin in histological studies. Diameter of isolated organisms I. multifiliis was measured ranges from 0.0505-1.1666 mm under microscope. The mean prevalence of I. multifiliis to Asala fry during rainy season (June 2007) estimated was 64.1 percent. The daily mortality rate of Asala fry, observed for nine days, due to I. multifiliis infestation ranged between 0.2 to 12.6 percent.

Title : Occurrence of Insect Pests and Diseases of Ginger in Nepal Material Type: printed text Authors: J. Gautam, Author Pagination: 69-72 p. Languages : English (eng) Keywords: Ginger, Insect pests, Occurrence, Yield. Abstract: A random field survey was conducted from August to September during hVo consecutive ginger
growing seasons in 20/J and2012 in the major ginger growing districts (lllam, Salyan Palpa,
Nawalparasi, Dhankuta, Syanja, Makawanpur, Tanahu and Surkhet) of Nepal. White grub
(Phyllophaga spp.), Ginger shoot borer (Dichocrosis punctiferalis Guen.), Red ant (Dory/us sp),
Termites (Odontotermes sp) and Leafroller (Udaspes folus) pest infestation were found in most of the
surveyed districts. Rhizome rot (Pythium sp) infestation was found associated with rhizome fly
(Calobata sp) in patches in almost all the surveyed districts. Among them white grub and rhizome fly
were found economically important insect pests in ginger.
Monitoring of insect species using Sigma energy saving lamp of 18 watt was conducted at National
Ginger Research Program (.148.0 mas/), Kapurkot, Salyan during 2011112. A total of 27 species of
insect pests collected throui,1 light trap were identified. However, only 6 different insects namely
· Phyllophaga serricolis Hope, Dory/us orienta/is, · Xylotrupes gideon L., Anomala xanthroptera
Blanchard, Areas galactina orienta/is and Nezara viridula L were observed for the population build
up trend. Phyl/ophaga serricolls Hope (38) and Xylotrupes gideon L. (98) showed the highest
occurrence in July where as other insect species during June. During winter season no any occurrence
of insect species were recorded in Kapurkot condition.Link for e-copy: http://elibrary.narc.gov.np/?r=1581 Occurrence of Insect Pests and Diseases of Ginger in Nepal [printed text] / J. Gautam, Author . - [s.d.] . - 69-72 p.
