A field experiment was carried out to determine the comparative efficacy of newer insecticides with botanical insecticides, viz., Chlorantraniliprole 0.4G @ 10 kg ha-1, Fipronil 5 SC @ 1500 ml ha-1, Acephate 95 SG @ 750 g ha-1, Lambda cyhalothrin 4.9 CS @ 550 ml ha-1, Thiamethoxam 25 WG @ 150 g ha-1 @ Carbofuran 3 CG @ 30 kg ha-1, Carbosulfan 25 EC @ 875 ml ha-1, Cedarwood oil @ 1000 ml ha-1, Azadirachtin 0.03 EC @ 2500 ml ha-1, applied at 20 and 35 DAT, against rice gall midge, Orseolia oryzae (Wood-Mason) in rice during kharif, 2019 and 2020. All the treatments were effective for gall midge. Lambda cyhalothrin 4.9 CS @ 550 ml ha-1 was significantly superior (>80% reduction over control) for gall midge management and grain yield was 4.75 t ha-1. Both botanical and untreated plots had more number of parasitized gall midge (40- 53.3%) than other chemical treated plots.

Rice Gall Midge

In an effort to study genome diversity within and between the Indian biotypes of the Asian rice gall midge, Orseolia oryzae, a major insect pest of rice, we made use of mariner transposable element integration site polymorphisms. Using degenerate primers, the design of which is based on mariner sequences, we amplified a ca. 450 bp mariner sequence from the rice gall midge. The mariner sequence showed homology with that of a mariner element isolated from the Hessian fly, Mayetiola destructor, a major dipteran pest of wheat. Southern hybridization, using this mariner fragment as a probe, revealed that the mariner elements are moderately to highly repetitive in the rice gall midge genome. Based on the sequence information of this 450-bp PCR-amplified fragment, outward-directed primers were designed and used in an inverse PCR (iPCR) to amplify the DNA flanking the conserved regions. To study the regions flanking the mariner integration sites, we employed a novel PCR-based approach: a combination of sequence specific amplification polymorphism (SSAP) and amplified fragment length polymorphism (AFLP). The outward-directed mariner-specific primer was used in combination with adapter-specific primers with 1–3 selective nucleotides at their 3' ends. The amplification products were resolved on an agarose gel, Southern-transferred onto nylon membranes, and probed with the iPCR fragment. Results revealed biotype-specific polymorphisms in the regions flanking the mariner integration sites, suggesting that mariner elements in the rice gall midge may be fixed in a biotype-specific manner. The implications of these results are discussed in the context of biotype differentiation.Key words: DNA fingerprinting, inverse PCR (iPCR), Oryza sativa, rice pest, transposon.
