eady-to-harvest fruits. Farmers lose their goodwill in market due to fruit fly
damage. He mentioned one example: previously Gadat co-op. society is well-known in
mango marketing but nowadays they have lost goodwill in the market due to FF damage.
Nowadays no known person purchases fruit from Gadat co-op. society. Fallen fruits are
responsible to develop fruit flies. In mixed crop, mango damaged up to 40 % and chiku
up to 10 to 15 %. 'Alpanso' and 'Kesar' varieties of mango are highly susceptible to
fruit flies while variety 'Totapuri' is less susceptible. He thinks it may be due to
sweetness as well as peel size.
MANAGEMENT: FRUIT FLY TRAP Co-op. society distributes traps along with insecticide
DDVP & attracting solution. He is installing 20 traps per ha., recharged at an
interval of 10-15 days. This technique is very effective. Sometimes they haven't time
to change the solution. Co-op. society distributes solution very late in the month of
April, but they think, as population high from January - February, there is necessary
to install trap in January. He noted those 10 traps per ha. is false recommendation
and trap number should be doubled.
TULSI Previously he grew tulsi plant to attract fruit flies and sprayed with
insecticide DDVP frequently.
COLLECTION OF FRUITS They collect damaged / fallen fruits. This method is good to
check further development of fruit flies. But a laborious job. Collected fruit are
buried in deep pit.

CROPS. Small farmer growing BG, sapota, mango, ladies finger, paddy with 9 family
members. He growing BG from last 3 years because it is high demanded veg. in local
market. He has 30 trees of sapota (steady income) & mango each (high market value
within short period). BG&PESTS Fruit flies cause heavy damage to BG fruits (early
mature, yellowing, falldown, unmarketable) up to 50% damage. He sprays crop with
mixt. of monocrotophos & DDVP suggested by his son, working as a Agri. assistant.
Spray gave a good result. Previously he was using ME traps, but there was no any
change in damage, satisfied by observing flies in traps. Unable to answer 'WHY?'
SAPOTA&PESTS Leaf miner & Bud Borer are the major problems, damaging leaves & buds(
10-15%loss). He thought that fruit flies in sapota feeds only fallen fruits so he
don't take any management practice.
MANGO&PESTS Fruit flies & Jassids are the main problems. By spraying monocrotophos &
DDVP, he controls Jassids completely but fruit flies are not managed. He said that
fruit flies feed inside fruits so chemicals are not working well.
#G006 DATE: 01/10/03 TEAM: ZPP/VSJ Village: Chari, Chikhali. He has 8 family members
with 2.5 ha. land.
CROPS He growing mainly mango, SG, Ladies finger, sugarcane, paddy
MANGO He has a 70 years old orchard of 1 ha.,planted at 10x10m distance. Varieties:
Alphanso, Kesar, Langdo, and Rajapuri. Crop is advantageous due to once harvested in
a year, less laborious, low fertilizer, less irrigation (3 irrigations), chemical
fertilizer is not necessary. Mango variety - Lagda is highly demanded in south
Gujarat & Rajstan. Keasar is utilized for small juice industries running in state.
Rajapuri is famous for pickles but due to low rate farmers' cutting-off this variety.
PEST 1. JASSIDS are the important as infestation start with flowering. it sucks the
cell sap from tender shoots & flowers latter turns in black shooty mould. High
infestation causes complete failure of crops (100% if not controlled). He got very
good result with Endosulfan & sulpher (1 spray) & Monocrotophos & Bavistin(II spray)
