No-choice Cage Technique to Screen for Resistance to Sorghum Midge (Diptera: Cecidomyiidae)

Mechanisms of Hybrid Sunflower Resistance to the Sunflower Midge (Diptera: Cecidomyiidae)

“…Single-plant adult cages were constructed following the design of Sharma et al (1988). Two plants of 'Northrup King 212', 'Interstate 894', 'Seedtec 315', and 'Seedtec 316' were exposed to sunflower midge adults at Mapleton.…”

Variation in inheritance of resistance to sorghum midge, Stenodiplosis sorghicola across locations in India and Kenya

“…As a result, sorghum midge emergence and oviposition varies over seasons and locations depending on sunrise, temperature, and relative humidity. Therefore, in addition to the natural infestation, the test material was also screened using no-choice headcage technique at ICRISAT, Patancheru, India (Sharma et al, 1988). Three panicles were infested with sorghum midge females under headcage in each replication.…”

“…Before infestation with the sorghum midges, the spikelets at the tip portion of the panicle, which had flowered the previous day, and the spikelets at the lower portion of the panicle, which may not flower over the next 2 days were removed with scissors. Wire-framed cages were then tied around the sorghum panicles, which were covered with blue colored cloth bags (Sharma et al, 1988). Sorghum midge females were collected in plastic bottle aspirators between 0800 and 1000 hr from flowering sorghum panicles, and 40 midge females were released inside each cage.…”

Genotypic effects of sorghum accessions on fecundity of sorghum head bug, Calocoris angustatus Lethiery

“…Head bugs collected from the field were reared on CSH 1 panicles (5 pairs/panicle) at the half-anthesis stage under the headcage to raise the insect culture for these studies (Sharma et al ., 1988 ;Sharma & Lopez, 1992a) . Twenty days after infestation, bugs were collected into 200 ml plastic bottles (5 pairs in each bottle) with an aspirator from the CSH 1 panicles, and were used for infesting different genotypes .…”

“…Ten panicles were tagged at random in each plot at half-anthesis . Each panicle was infested with 5 pairs of bugs/panicle using the headcage technique (Sharma et al ., 1988) . The number of bugs produced from 5 pairs of bugs on each panicle were counted 20 days after infestation .…”
