Mirgund, Sher-e-Kashmir University of Agricultural Sciences & Technology of Kashmir, Shalimar, J&K *Corresponding Author E-mail: [email protected] Received: 27.11.2017 | Revised: 8.12.2017 | Accepted: 15.12.2017 ABSTRACT One of the major factors that decides the productivity and profitability in sericulture is the maximization of quality mulberry leaf per unit area. Being a major pest, Glyphodes pyloalis walker takes a heavy toll of mulberry especially from July to October under Kashmir climatic conditions. The damage is mainly caused by the fourth and fifth larval stage of the pest from July to October under Kashmir conditions Though this insect still finds enough time and place on mulberry leaves for its feeding and breeding habits, feeding of such leaves to silk worms affects their growth and development, thereby reducing the quality silk production which ultimately has negative impact on overall growth of silk industry. Key words: Glyphodes pyloalis, Pest, Mulberry, Sericulture, Kashmir.

Crambidae, Spilomelinae, box tree moth, generic placement, Diaphania, Glyphodes, Neoglyphodes, Palpita, Cydalima perspectalis, new combination, taxonomy, phylogeny, morphology, nomenclature Abstract. The box tree moth, Cydalima perspectalis (Walker, 1859) comb. n., is native to India, China, Korea, Japan and the Rus- sian Far East. Its larvae are a serious pest of different species of Buxus. Recently, C. perspectalis was introduced into Europe and first recorded from Germany in 2006. This species has been placed in various spilomeline genera including Palpita Hübner, 1808, Diaphania Hübner, 1818, Glyphodes Guenée, 1854 and the monotypic Neoglyphodes Streltzov, 2008. In order to solve this nomen- clatural confusion and to find a reasonable and verifiable generic placement for the box tree moth, the morphology of the above mentioned and some additional spilomeline taxa was investigated and their phylogeny analysed. The results show that C. perspec- talis belongs to a monophylum that includes three of the genera in which it was previously placed: Glyphodes, Diaphania and Pal- pita. Within this monophylum, it is closely related to the Asian Cydalima Lederer, 1863. As a result of this analysis, Sisyrophora Lederer, 1863 syn. rev. and Neoglyphodes Streltzov, 2008 syn.

Raya Bogor Km. 46, Cibinong, 16911 Indonesia E-mail: [email protected] Abstract The phylogeny of Glyphodes Cuenee (14 species) and [our outgroup species (Feltia jaculifera, Metallarcha aureodiscalis, Talanga sexpunctalis and Agrioghrypta eurytusalis) was inferred from nucleotide sequence variation across a 686-bp region in the CO I gene. Over the entire 686-bp region, 19.9% sites were informative (3.35% in the 1"-, 0.29% in the 2''''- alld 16.32% in 3"'-codon position). The results also showed that the base composition of this region was high A+T biased (C= 0.258) and the averages of estimated sequence divergence in the comparisons between species within and between groups were 7.1% and 9.0%, respectively. In general, the phylogeny based 011 CO Igene by including all substitutions or any partial data set used in this study was not only able to recover almost the three monophyletic groups within Glyphodes as previously recovered by morphological phylogeny but also showed more clearly the relationships among them: Glyphodes group 2 was branched off first then followed by group 3 and 1. Key words: CO I, Gbjphodes, morphology, phylogeny. Introduction The Glyphodes Cuenee, 1854, is medium-sized moth (15-51 mm) belongs to the subfamily Spilomelinae (Common, 1990; Shaffer et al., 1996). This genus is diverse and widespread in tropical regions with some species penetrating into subtropical and warm temperate areas (Common, 1990;Robinson et al., 1994).The genus consists of 120 species throughout the world, and about 25 and 17 species have been recorded in the Southeast Asia and Australia, respectively (Robinson et al., 1994; Shaffer et al., 1996).

  • Effectiveness of Lightning Pheromone Application Against Mulberry Glyphodes Pylaialis W
    E3S Web of Conferences 244, 02030 (2021) https://doi.org/10.1051/e3sconf/202124402030 EMMFT-2020 Effectiveness of lightning pheromone application against mulberry Glyphodes pylaialis W. Z. Nosirova1,* and M. Tojieva1 1Tashkent State Agrarian University, University str., 2, Tashkent province, Uzbekistan, 100140 Abstract. An analysis of the results of experiments to determine the effectiveness of the use of illuminated pheromone catchers in the fight against mulberry moth was presented. The experiments used pheromone handles impregnated with antioxidant pheromone material and placed on a lamp based on 2 light-emitting diodes operating in the ultraviolet radiation range of 365-370 nm. According to the analysis of the results, it was observed that mulberry moths caught on illuminated pheromone traps were 2.15 times more than non-illuminated catches, and the number of moths caught at night was about 1.75 times higher than the number of moths caught daytime. 1 Inroduction It is known that pheromone traps play a role in pest control activities. The main reasons for this can be explained by the fact that this method is completely harmless to the environment, water, soil, agricultural workers, and the cost of implementation is relatively low. Research conducted by our Russian colleagues has tested more than 70 species of pheromones and sex attractants of forest tree pests, and noted their promising role in protecting plants from pests [1]. Proof of this idea can be taken from recent studies that have been used against corn crop pests and have given relatively good biological efficacy. In this paper, experiments were conducted to determine the effectiveness of conical and aspiration pheromone traps, and it was shown that the efficiency of conical traps is higher [2].

Spilomelinae and Pyraustinae form a species-rich monophylum of Crambidae (snout moths). Morphological distinction of the two groups has been diffcult in the past, and the morphologically heterogenous Spilomelinae has not been broadly accepted as a natural group due to the lack of convincing apomorphies.

  • Natural Enemies of Mulberry Pyralid, Glyphodes Pyloalis Walker (Lepidoptera: Pyralidae), in Temperate Climate of Kashmir
    Journal of Biological Control, 25 (1): 55–57, 2011 Research Note Natural enemies of mulberry pyralid, Glyphodes pyloalis Walker (Lepidoptera: Pyralidae), in temperate climate of Kashmir VISHAL MITTAL, IRFAN ILLAHI, ANIL DHAR and M. A. KHAN Central Sericultural Research & Training Institute, Central Silk Board, Pampore 192 121, Jammu and Kashmir, India. E-mail: [email protected], [email protected] ABSTRACT: The incidence of natural enemies on the mulberry pyralid, Glyphodes (=Margaronia) pyloalis Walker (Lepidoptera: Pyralidae) infesting mulberry crop was studied at Pampore, Kashmir during 2008 and 2009 cropping seasons. Five hymenopteran parasitoids including three braconids (Apanteles obliquae Wilkinson, Bracon hebetor Say and Chelonus carbonator Marshall) and two ichneumonids (Pristomerus sulci Mahdihassan and Kolubajiv and Xanthopimpla sp.) were found to parasitize the larvae. Two predators, viz. Tetragnatha sp. (Araneae: Tetragnathidae) and Philodromus sp. (Araneae: Philodromidae) were also recorded. The activity of these natural enemies was observed from July to October in the cropping period spread over May-October. KEY WORDS: Glyphodes pyloalis, Kashmir, mulberry, natural enemies (Article chronicle: Received: 11.10.2010; sent for revision: 02.11.2010; Accepted: 27.11.2010) Mulberry (Morus sp.) is the only host plant of Mulberry cropping period spans from May to silkworm, Bombyx mori L. and is ravaged by different October in temperate conditions of Kashmir.

Recently, the silk trade, both within and outside the region, has become complex and competitive. To cope with this situation, there is a need to increase production as well as to improve the quality of silk. How­ ever, one of the most serious problems faced by many countries of the region in such efforts is the incidence of pests and diseases of both mulberry and silkworms. Indeed, cocoon and raw silk production, and ultimately the quality of silk produced, depend heavily on the success of silkworm rearing, and pests and diseases are an important factor affecting the productivity of silkworms. Thus, an effective means of increasing the production of silk and improving its quality is the control of such pests and diseases.
