1979 Laboratory experiments were carried out to test 13 insecticides against adults of B. cucurbitae Coq., reared from
naturally infested bitter gourd (Momordica charantia) and fed on pumpkin, using malathion as the standard. On
the basis of the LC50s, determined by the dry film technique, fenitrothion was 106.9 times, tetrachlorvinphos was
101.3 times, phosalone was 31.5 times, chlorpyrifos was 22.1 times, carbaryl was 17.8 times, fenthion was 13.8
times, quinalphos was 9.1 times, parathion-methyl was 8.8 times, trichlorphon was 6.7 times, diazinon was 1.5
times, gamma -BHC (lindane) was 0.7 times and endosulfan was 0.8 times as toxic as malathion, for which the
LC50 was 0.01009%.
1982 0.025% fenitrothion better than malathion.
Jujube New Delhi Gyi et al. 2003 Field experiments were conducted during 2000/01 and 2001/02 in New Delhi on 15-year-old ber cv. Gola to study
the effects of lambda-cyhalothrin and beta-cyfluthrin residues. The bio-efficacy of lambda-cyhalothrin and betacyfluthrin
against the fruit fly Carpomyia vesuviana was also studied. The treatments comprised 8 sprays at 15
day intervals of 0.25 mg lambda-cyhalothrin and 18.75 mg beta-cyfluthrin/litre. The residues declined to nondetectable
levels (< 0.007 mg/kg) in 14 days. The initial deposits of beta-cyfluthrin varied from 0.56 to 0.76 mg/kg
from both the years. beta-Cyfluthrin was not detectable after 7 days of the third spray in the first year and after 10
days in the second year. lambda-Cyhalothrin (12.38 and 11.02% of fruits damaged) was the most effective
against C. vesuviana.
Jujube New Delhi Gyi et al. 2003 Two field trials were conducted in New Delhi during 2000/01 and 2001/02 to evaluate the efficacy of endosulfan
(0.07%), lambda-cyhalothrin (0.0025%), beta-cyfluthrin (0.00187%), cartap hydrochloride (0.05%), nimbecidine
[azadirachtin] (5 ml/litre), Neemazal F (1 ml/litre), and alternate sprays of endosulfan and Neemazal against
Carpomya vesuviana infesting ber [Ziziphus mauritiana] (cv. Gola). Eight sprays of insecticides were given at 15day
intervals, commencing from the appearance of infestation. Infestation was recorded at harvest. The lowest
mean C. vesuviana infestation (13.7%) was recorded with lambda-cyhalothrin treatment in the 2000/01 cropping
season, followed by beta-cyfluthrin (15.1%). The highest mean infestation (37.3%) was recorded with
nimbecidine treatment. Similar observations were recorded in 2001/02.

and nine days, respectively.
Hameed et al. 1980 Toxicity and persistence of residues of some organophosphorous insecticides applied for the control of B.
cucurbitae Coquillet on the fruits of cucumber. In the laboratory, fenitrothion and parathion-methyl were found to
be highly toxic to newly hatched larvae of B. cucurbitae Coq. Malathion and trichlorphon were intermediate, and
fenthion was the least toxic of the compounds tested.
