B. cucurbitae Singh et al. 2000 The host preferences <strong>of</strong> the red pumpkin beetle, Aulacophora foveicollis, <strong>and</strong> the melon fruit fly, B. cucurbitae, were<br />

studied using different cucurbits during the summer.The percentage <strong>of</strong> fruit damage by the melon fruit fly was under<br />

50% in all cases. However, percentage damage was significantly highest on watermelon (28.55%) <strong>and</strong> bitter gourd<br />

(31.27%).<br />

B. cucurbitae Melon? Tewatia <strong>and</strong><br />

Dhankhar<br />

1996 Inheritance <strong>of</strong> resistance to melon fruitfly was studied in 2 crosses <strong>of</strong> resistant Faizabad 17 X susceptible Pusa do<br />

Mausami <strong>and</strong> susceptible Arka Harit X resistant Kerala 1. Data on the percentage <strong>of</strong> infested fruits were recorded in<br />

parent lines, F1, F2, BC1 <strong>and</strong> BC2. Results indicated that resistance is dominant over susceptibility, <strong>and</strong> both<br />

additive <strong>and</strong> dominance gene effects were important in inheritance <strong>of</strong> resistance. However, a duplicate type <strong>of</strong><br />

epistasis was noted. For further genetic improvement, reciprocal recurrent selection is suggested.<br />

B. cucurbitae Bitter gourd Thakur et al. 1994 Stability analysis for economic traits <strong>and</strong> infestation <strong>of</strong> melon fruit-fly (B. cucurbitae) in bittergourd (Momordica<br />

charantia) were studied. 10 cultivars were sown out <strong>of</strong> which C96 was the most stable for fruits/plant <strong>and</strong> had the<br />

lowest incidence <strong>of</strong> fruit fly infestation. NDBT1 had the most stable resistance to B. cucurbitae.<br />

B. cucubitae Bitter gourd Ludhiana,<br />

Punjab<br />

Thakur et al. 1996 Information on yield correlations is derived from data on 7 characters (including fruit fly B. cucurbitae infection <strong>and</strong><br />

total yield) in 10 Momordica charantia varieties (BG14, Arka Harit, Kalyanpur Sona, ARU41, NDBT1, Pusa Do<br />

Mausmi, Priya, Pusa Vishesh, Pusa Hybrid-1 <strong>and</strong> C96) grown at Ludhiana (Punjab). B. cucurbitae infection was<br />

negatively correlated with fruits/plant <strong>and</strong> total marketable yield. BG14 was the most promising variety with respect<br />

to yield components <strong>and</strong> B. cucurbitae resistance<br />
