1983 The oviposition behaviour of Carpomyia vesuviana Costa on ber (Ziziphus mauritiana), fruit deformity resulting from
infestation and the incidence of the pest were studied in Haryana, India, between 1979 and 1981. Females
preferred to oviposit in the distal or central part of the fruit. Oviposition inhibited growth in the surrounding tissues,
causing protuberances and/or depressions in the fruit. Deformity was most apparent in young fruits with oviposition
holes. Fruits smaller than 9 X 4.5 mm were avoided by females, while almost 50% of fruits measuring 20 X 9 mm
contained oviposition holes during October. A maximum of 55.15% of fruits contained a single larva, while 37.16%
contained 2 or 3. Only 0.08% of fruits contained 7 or 8 larvae. A total of 45% of fruits was infested by 2-8 larvae at
some stage during of their development. Of the infested fruits, 21.83% were collected from the southern side of
trees, while only 5.27% were taken from the northern side; the percentages taken from the eastern and western
sides were almost equal (14.6 and 14.5, respectively). The pest was most abundant in December and least
abundant in March.
Bc? 29 cucurbits Lall and Sinha 1974 The percentage of infested fruit was assessed weekly over a four-week period for six bittergourd (Momordica
charantia), six pumpkin (Cucurbita pepo), five sponge-gourd (Luffa cylindrica), five bottle-gourd (Lagenaria
siceraria) and seven cucumber (Cucumis sativus) cultivars. The cultivars exhibiting most resistance for the five
species respectively were Short Green Kareli, Small Sugar, Pilibhit Padmini, Sutton's Long White and Improved
Long Green.

Mann 1996 B. dorsalis flies were observed throughout the year in methyl eugenol baited traps in a mango orchard in Ludhiana,
Punjab, India. Population counts were low in the winter months from December to February which was thought to
be caused by low temperature (below 20°C). Following the warmer season, the flies rebuilt their population
throughout the rest of the year. However, low catches in July may be due to the after-effects of high temperatures in
June (31.93°C) or due to high rainfall (223 mm/month). Afterwards, increases in fruit fly catches may be attributed to
conducive temperature (24-29°C) and abundant supply of host fruits. The fruit fly counts on the mango fruits during
July were greatest at 1100 h and 1200 h. Fruit fly infestation was 30.77, 65 and 85.50% in cultivars Dusheri,
Sucking and Chausa, respectively.

1977 Field incidence of B. dorsalis Hendel on different cultivars of peach (Prunus persica) at Ludhiana (Punjab)studies
over two years with eleven varieties, Florida Sun had the lowest average infestation; generally, infestation was
related to earliness of fruiting, the earlier the variety the lower the infestation, except in the midearly variety Sun
Red, in which infestation was heavy, possibly because the fruit lack hairs.
1996 In a field study in 1995-96 at Bijapur, Karnataka, in Zizyphus mauritiana orchards, Meridarchis scyrodes and
Carpomyia vesuviana were prevalent from first fortnight of December to first fortnight of February. The relationship
between pest incidence and temperature was positive while negative relationship of the incidence of the pests was
found with relative humidity, wind speed and cloud cover. M. scyrodes was more damaging than C. vesuviana in all
the cultivars evaluated. Cv. Ilaichi and Chhuhara fruits recorded lowest pest infestation (1 larva/fruit).
