Title : Damage assessment of rice due to rice bug, Leptocorisa oratorius (Fabricius) (Hemiptera: Alydidae) Material Type: printed text Authors: Gyawali, B.K. Pagination: 127-135 p. Languages : English (eng) Abstract: Assessment of damage of rice grains to the rice bug, Leptocorisa orator/us (F.), was carried
out in the command area of Sunsari, Bara Chitwan, Rupandehi and Banke districts in Terai,
during the wet season of 1994iii'd 1 mr-and 'Qryseason ~6 in Klvre district in the hill.
The percentage of filled grains with stylet sheaths were found 0.38 during 1994 and 0.55 in
1995 in normal rice where as in the early rice it was recorded 1.95 during 1996. Similarly the
percentage of unfilled grains with stylet sheaths found to be 0.14 and 1.06 in normal rice
during 1994 and 1995 respectively; where as in early rice the damage was 1.15 percent in
1996. The filled non-punctured grains were recorded at 79.44 and 87.66 in normal rice of
1994 and 1995, respectively; and also in early rice filled non-punctured grains were found to
be 80.18 percent during 1996. Similarly, the percentage of unfilled non-punctured grains
were 20.11 and 10.99 in normal rice during 1994 and 1995 and 17.61 in early rice during
1996. The acid fuhsine method was the most accurate and reliable method to quantify rice
bug damage. The unfilled grins could be probably due to some other reasons such as
physiological disorder, nutrient imbalance and genetic make-up of a rice cultivar rather
than rice bug damage alone.Link for e-copy: http://elibrary.narc.gov.np/?r=492 Damage assessment of rice due to rice bug, Leptocorisa oratorius (Fabricius) (Hemiptera: Alydidae) [printed text] / Gyawali, B.K. . - [s.d.] . - 127-135 p.

Title : Development of ipm package for vegetable crops specially tomato in Nepal Material Type: printed text Authors: Gyawali, B.K., Author ; Colavito, Luke A., Author ; G Thapa, Author Pagination: 410-412 p. Languages : English (eng) Abstract: Attempts were made to identify pest problems of tomato from seedlings to harvesting stage of tomato, and to develop IPM package. Different formulations of bio-fertilizers and bio- pesticides were evaluated. Combined effect of bio-fertilizers and bio-pesticides on fresh yield of tomato var. Srijana was significantly high as compared to rest of the treatments. Some of the practices adopted include mulching, selection of resistant variety (against wilt) as a scion and grafting resistant rootstock (against root knot nematode), seed treatment with microbial consortium, raise seedlings in poly bags, use of solarized soil, bio-fertilizers, bio-pesticides- amended farm yard manure. Regular monitoring and scouting of major pests were carried out using pheromones and traps for need-based control decision using economic threshold level (ETL).
