| dc.description | The cucurbits are most important group of vegetables which occupy 66 percent of the land
under vegetable production in Bangladesh and contribute 11 percent of total vegetable
production in the country (IPM CRSP, 2004). Among the cucurbit vegetables cultivated in
Bangladesh, bitter gourd (Momordica charantia L.) is now drawing attention to greater
extents covering an area of 5,502 hectare with a total production of 20,470 tons (Anonymous,
2004). Bitter gourd is a tropical and subtropical vine belonging to the family Cucurbitaceae.
It is found most bitter in taste among all the vegetables due to the presence of momordicin as
the name literally suggests. The fruits, young shoot and flowers are consumed as vegetables
and are nutritionally rich in vitamins and an excellent source of iron and calcium. The
immature fruits and the tender leafy shoots or the ripe fruits have both nutritional as well as
medicinal importance (Khan and Anderson, 2003) like potential health benefits to diabetes,
arthritis, rheumatism, asthma, warts, abscesses and ulcers. A compound named 'Charantin'
present in the bitter gourd is useful to reduce blood sugar for diabetic patients (Dhillon ef al.
2005). | en_US |
| dc.description.abstract | An investigation was conducted to study the susceptibility of different bitter gourd varieties
viz. tia, heeradill, bulbuli, masrangha, goghkorolla, poran, green queen and sonamukhi to
cucurbit fruit fly, Bactrocera cucurbitae (Coq.) based on biophysical fruit traits conducted
both in the field and laboratory conditions during the period of February to July 2014. The
percent fruit-infestation and larval density were significantly varied among the bitter gourd
varieties. The larval density had a significant positive correlation with percent fruit
infestation. Biophysical fruit traits like fruit length, fruit diameter, number of longitudinal
ribs and small ridges were the lowest in resistant and the highest in susceptible varieties
which showed a significant positive correlation with the percent fruit infestation. Additionally
the height of longitudinal ribs, depth of small ridges, pericarp thickness and fruit toughness
were the highest in resistant and the lowest in susceptible varieties. These parameters showed
negative correlation with the percent fruit infestation. It is evident from the results that
goghkorolla (19.39 %) categorized as resistant whereas masrangha (41.91 %), tia (46.09 %)
and sonamukhi (50.00 %) categorized as moderately resistant varieties. Heeradil (58.89%),
green queen (59.05 %), poran (59.44 %) and bulbuli (69.06 %) categorized as susceptible
varieties at early fruiting stage. Contrarily, at mid fruiting stage all varieties were susceptible
to fruit fly except sonamukhi (46.69 %). Meanwhile, in late fruiting stage all tested varieties
showed susceptibility to cucurbit fruit fly. The weight reduction in three different fruiting
stages for all bitter gourd varieties was found to be differed and the highest weight reduction
obtained from bulbuli and the lowest was the variety of sonamukhi. Among the tested bitter
gourd varieties the order of infestation intensity was found as green queen > bulbuli > poran
> tia > goghkorolla > heeradil > masrangha > sonamukhi at all three fruiting stages. | en_US |
