Description The present investigation was undertaken for screening of white button
mushroom, Agaricus bisporus (Lange) Singer strains, evaluating botanicals for
management of mushroom flies and studying the population dynamics of flies.
The material for screening comprised of five strains of A. bisporus, eight
medicinal plant extract, two insecticide and a light trap with a yellow polythene
and 15 watt yellow bulb. These experiments were carried out at Department of
Plant Pathology and Department of Entomology, CCS Haryana Agricultural
University, Hisar during 2004-05 season and CRD design with three replication
was followed for layout.
There was no infestation of phoridfly whereas maximum (16.67%) and
minimum (7.25%) infestation of sciaridfly was in S-791 and P-31, respectively,
in the early crop. Infestation of phorid fly was maximum (40.51%) in S-791 and
lowest (30.95%) in S-100 whereas sciarid infestation was maximum (22.49%) in
S-791 and minimum (10.98%) in P-31, in late crop.
All the strains showed moderate feeding by sciarid fly larvae except S-791
which had highly feeding while all the strains showed highly feeding by phorid
fly.
Number of sciarid larvae per infested fruiting body were maximum (5.2) in
S-791 and minimum (2.9) in P-31 during early crop while in the late crop,
maximum (7.1) were in S-791 and minimum (4.1) in HU-3. Phorid larvae were
maximum (22.7) in S-791 and minimum (12.7) in S-100 in the late crop.
Sciarid larvae in spawn-run compost cup were maximum (16.2) in S-791
and minimum (10.0) in S-11 whereas maximum (26.5) number of phorid larvae
were in S-791 and lowest (18.7) were in S-100.
Spawn run time was longer in all the botanical treatments over control.
Maximum spaw-run inhibition (3.00 day) was noticed in Ashvagandha
treatment while minimum inhibition (0.33 day) was in Sarpgandha treatment. It
was shorter by 0.33 day in endosulfan 35 EC treatment. All the botanicals
treatments decrease the per cent infestation of mushroom flies significantly over
the control but no botanical was at par with checks (Endosulfan 35 EC and
Nimbecidine 300 ppm). Minimum infestation (21.56%) was observed in neem
treatment whereas maximum (43.80%) was in Gurmar treatment.
No botanical treatment gave the high yield over checks. Yield was
maximum (10.20 kg/q compost) in Turmeric treatment and minimum (8.66
kg/q compost) in Gurmar and Senna treatments. Avoidable losses was highest
(14.4%) in Turmeric and there was no avoidable loss in Gurmar and Senna.
Phorid fly population shows positive correlation r= 0.553 with
temperature while sciarid fly had no correlation with temperature having r=
0.036.
