“…This results in noticeable change in growth of surrounding tissue that encircles the maggot to form a gall chamber and form nutritive nurse cells (i.e. shifting of the metabolic process from a reproductive phase to a vegetative phase) 1 . Maggot molts twice and passes through three instars prior to pupation within the now tubular gall.…”

“…Successful establishment of the insect in the plant and formation of gall renders that tiller sterile without further formation of panicles and grains that result in economic loss. However, several of the rice genotypes resist insect establishment and gall formation offering genetic host-plant resistance 1 . Gall flies lay eggs almost indiscreetly with reference to such genotypes and egg hatching or movement of hatched maggots into the plant to reach apical meristem is not hindered.…”

The Asian rice gall midge (ARGM) has emerged as a model gall forming pest of rice. The ARGM infestation of rice results in failure of panicle formation and economic loss. Understanding the molecular basis of ARGM-rice interactions is very crucial in order to control this devastating pest of rice. The current investigation was devised to identify bacterial communities present in the ARGM and in addition the bacterial diversity in the maggots during their interaction with susceptible or resistant rice varieties. Sequencing of 16S rRNA bacterial gene (V3-V4 region) revealed differences in the microflora of the ARGM maggots feeding on susceptible or resistant rice hosts. Results revealed that Wolbachia was the predominant bacterium in pupae and adults while Pseudomonas was predominant in maggots. Further, we observed that members of proteobacteria were predominant across all the samples. There was high species diversity in maggots isolated from susceptible rice and a high representation of unclassified bacteria in maggots isolated from resistant rice. This is the first study that reports variation of microbiome of the ARGM, based on host phenotype from which it was isolated, and results suggest that these variations could have an important role in host’s susceptibility.

“…Asian rice Gall-midge (GM), Orseolia oryzae (wood-mason), is a serious pest of rice in China, India, Sri Lanka, and several other countries (Katiyar et al, 2000). So far 11 GM resistance genes have been acknowledged in various rice varieties, Gm1, Gm2, gm3, Gm4, Gm5, Gm6, Gm7, Gm8, Gm9, Gm10 , and Gm11(t) (Dutta et al, 2014; Das and Rao, 2015; Hasan et al, 2015; Bentur et al, 2016). The brown plant hopper (BPH), Nilaparvata lugens , has been one of the most devastating pests to rice crops in Vietnam and Asia.…”

Rice yield is subjected to severe losses due to adverse effect of a number of stress factors. The most effective method of controlling reduced crop production is utilization of host resistance. Recent technological advances have led to the improvement of DNA based molecular markers closely linked to genes or QTLs in rice chromosome that bestow tolerance to various types of abiotic stresses and resistance to biotic stress factors. Transfer of several genes with potential characteristics into a single genotype is possible through the process of marker assisted selection (MAS), which can quicken the advancement of tolerant/resistant cultivars in the lowest number of generations with the utmost precision through the process of gene pyramiding. Overall, this review presented various types of molecular tools including MAS that can be reasonable and environmental friendly approach for the improvement of abiotic and biotic stress resistant rice with enhanced quality.

Brown planthopper (BPH) emerged as serious pest of rice in Asia as a result of green revolution. BPH outbreak is supported by its monofagous feeding behavior on rice, high fecundity, and ability to long distance migration. BPH is labile in virulence and capable of rapid adaptation on new resistant varieties. The terminology 'biotype' to describe BPH virulence is still debatable because of individual virulence and genetic variation within a biotype. This paper reviews the biology, biochemistry, interaction with endosymbionts, and genetics aspects of BPH to reveal virulence basis of BPH for improvement of BPH management strategies. At the molecular level, differential expression profiles of genes related to digestion, saliva secretion, detoxification, metabolisms of lipid, carbohydrate, amino acid, and nitrogen; signaling pathways of defense, stress, and immunity responses were noted among BPH population with differential virulence. Research in genomics revealed complementary interaction between BPH and endosymbiotic microorganisms, but experiments using aposymbiotic BPH showed that endosymbiont densities do not always positively correlated with BPH virulence. In contrast to the previous finding, recent genetic mapping of BPH Avr gene using inbred populations revealed that BPH virulence is monogenically controlled. With this finding, a gene-for-gene relationship between BPH and its host can been established. Strategies for utilizing resistant varieties to anticipate virulence adaptation according to the dynamics of resistant rice varieties deployed in the field are discussed in this paper.Keywords: Brown planthopper, virulence, biotype, adaptation, endosymbiont. ABSTRAKWereng batang cokelat (WBC) timbul menjadi hama utama padi di Asia sebagai dampak revolusi hijau. Ledakan populasi WBC didukung oleh perilaku WBC yang monofagus pada padi, keperidian tinggi, dan kemampuan migrasi jarak jauh. WBC bersifat labil dalam virulensi dan mampu beradaptasi pada varietas tahan. Penggunaan istilah 'biotipe' untuk pengelompokan virulensi WBC masih diperdebatkan karena adanya variasi virulensi dan genetik antarindividu dalam satu biotipe. Makalah tinjauan ini membahas aspek strategi hidup dan makan, biokimia, interaksi dengan endosimbion, dan genetik WBC untuk mengetahui basis adaptasi virulensi WBC sehingga dapat digunakan dalam perbaikan strategi pengelolaan hama ini. Pada level molekuler, virulensi ditandai dengan peningkatan profil ekspresi gen-gen yang berkaitan dengan detoksifikasi senyawa alelokemik tanaman; metabolisme lipid, karbohidrat, asam amino, dan nitrogen; jalur lintas penyinalan respons pertahanan, respons terhadap cekaman, dan respons kekebalan. Penelitian genomik mengungkap interaksi komplementer antara WBC dan mikroorganisme endosimbion, tetapi percobaan menggunakan WBC aposimbiotik menunjukkan bahwa kepadatan endosimbion tidak selalu berkorelasi positif dengan virulensi WBC. Bertolak belakang dengan hasil-hasil penelitian sebelumnya, pemetaan genetik gen virulensi menggunakan tetua inbred menunjukk...
