In São Paulo State there are mulberry some hybrids whose productivity are higher than the commonly cultivated varieties. The objective of this study was to evaluate the effect of mulberry hybrids (Morus spp.) on the cocoon production of silkworm (Bombyx mori L.). The experiment was conducted at the Unidade Regional de Pesquisa de Gália do Instituto de Zootecnia, SP. The caterpillars were fed on leaves of the hybrids IZ-3/2, IZ-13/6, IZ-15/7, IZ-19/13, IZ-56/4, IZ- 57/2, IZ- 40, IZ-64, in a rearing hut at 25 oC ± 3 oC and 75% ± 5% relative humidity. 'Korin' was used as standard. The hybrids affected the duration of the larval period and the weight of the caterpillars, prepupaes and the silk glands as well. There was a reduction in the duration of larval development when the caterpillars had been fed with hybrid IZ-56/4 and the 'Korin' variety. Hybrids IZ-57/2, IZ-56/4 and IZ-15/7 presented the highest cocoon production. Keywords Biology, Insecta, Sericulture, Silkworm.

Insects have several genes coding for insulin-like peptides and they have been 18 particularly well studied in Drosophila. Some of these hormones function as growth hormones 19 and are produced by the fat body and the brain. These act through a typical insulin receptor 20 tyrosine kinase. Two other Drosophila insulin-like hormones are either known or suspected to act 21 through a G-protein coupled receptor. Although insulin-related peptides are known from other 22 insect species, Drosophila insulin-like peptide 8, one that uses a G-protein coupled receptor, has 23 so far only been identified from Drosophila and other flies. However, its receptor is widespread 24 within arthropods and hence it should have orthologs. Such putative orthologs were recently 25 identified in decapods and have been called gonadulins.

Accepted 11 March, 2010 In this study, the resistance difference to phoxim between Bombyx mori L. and Bombyx mandarina M was investigated. For the both silkworm species, the whole body of each larval were collected, and on the third day of the 5th instar, the brain, midgut, fat bodies, and silk gland were collected for enzymatic activity assay of acetylcholinesterase (AChE). Our results showed that in the early larval stages, the resistance difference to phoxim was not significant between the two species. However, in the 4th and 5th instar, the resistance differences showed significant increase. When compared to B. mori L, the LC50 of B. mandarina was 4.43 and 4.02-fold higher in the 4th and 5th instar, respectively. From the 1st to 5th instar, the enzymatic activities of AChE of B. mandarina were 1.60, 1.65, 1.81, 1.93 and 2.28-fold higher than that of B. mori, respectively.

El-Shewy A.M. and Elgizawy K. KH Plant Protection Dept., Fac. of Agric. Moshtohor, Benha Uni., Egypt. Received: 11 Sept. 2017 / Accepted: 04 Dec. 2017 / Publication date: 20 Dec. 2017 ABSTRACT Nutrition has an important role in improving growth and development of the silkworm Bombyx mori L. Although B. mori L. larvae are normally reared on mulberry leaves (Morus alba), those can be successfully reared on leaves of alternate plants. The aim of this study was to evaluate the effect of alternate plants, namely grapes leaves, Bougainvillea glabra, Lettuce sativa, Lantana camara and Ficus retusa with different concentrations of mulberry leaves powder aiming to increase the silk and egg production of Bombyx mori L., and also to improve low nutritional value of autumn rearing season. The results showed that treatment of mulberry leaves powder with grape leaves at 1 and 2% concentrations resulted high consumption of food. That was followed by lettuce leaves and Bougainvilleg leaves. While, lantana camara and Ficus retusa leaves caused the least consumption of food. It was also found that, grapes and lettuce leaves caused significant increases in all the tested biological and physiological parameters during autumn season. Also, the new alternate food produced healthy cocoons and increased of eggs production. Meanwhile, the alternate plants lantana comara and Ficus retusa were the least efficient treatments.

Eggs, larvae and pupae of the pest were all present on the infested shrubs. The larvae completely defoliated and eventually killed some of the Ficus plants . At the peak of infestation, larvae can consume all of the leaves of an individual shrub in just overnight. T. varians was also observed infesting jackfruit in Los Baños, Laguna and Balete, Batangas as well as on F. nitida in Baguio City . The nature of damage, host response and host range were discussed. This is the first record of T. varians as pest of Artocarpus heterpphyllus, A. communis , A. kamansi and some ornamental species of Ficu s in the Philippines. Key words: damage, host range, invasive pest INTRODUCTION The Philippines for the last several years was affected by outbreaks and isolated serious infestations of invasive pest species - Stenocranus pacificus Kirkaldy on corn, Nipaecocus nipae (Maskell), Brontispa longissima Gestro, and Aspidiotus sp., a species of scale insect, all on coconut, as well as native species like Spodoptera exempta (Walker) on graminaceous crops and weeds.

Antennapedia Is Involved in the Development of Thoracic Legs and Segmentation in the Silkworm, Bombyx Mori
Heredity (2013) 111, 182–188 & 2013 Macmillan Publishers Limited All rights reserved 0018-067X/13 www.nature.com/hdy ORIGINAL ARTICLE Antennapedia is involved in the development of thoracic legs and segmentation in the silkworm, Bombyx mori P Chen1,3, XL Tong1,3,DDLi1,MYFu1,SZHe1,HHu1, ZH Xiang1,CLu1 and FY Dai1,2 Homeotic genes, which are associated closely with body patterning of various species, specify segment identity. The Wedge eye-spot (Wes) is a new homeotic mutant located on the sixth linkage group. Homozygous Wes/Wes embryos are lethal and display a pair of antenna-like appendages under the mouthparts as well as fused thoracic segments. These mutants also exhibit a narrower eye-spot at the larval stage compared with the wild type. By positional cloning, we identiﬁed the candidate gene of the Wes locus, Bombyx mori Antennapedia (BmAntp). Two BmAntp transcripts were identiﬁed in the homozygote of the Wes mutant, including a normal form and an abnormal form with a 1570-bp insertion. Our data showed that the insertion element was a long interspersed nuclear element (LINE)-like transposon that destroyed the original open reading frame of BmAntp. Quantitative RT-PCR analysis showed that the expression levels of normal BmAntp transcripts were increased markedly in the Wes heterozygous larvae compared with the wild type. Furthermore, we performed RNAi of BmAntp and observed fused thoracic segments and defective thoracic legs in the developing embryos. Our results indicated that BmAntp is responsible for the Wes mutant and has an important role in determining the proper development of the thoracic segments.

Implications of Genetic Diversity in the Improvement of Silkworm Bombyx Mori L
REVIEW Implications of genetic diversity in the improvement of silkworm Bombyx mori L. Ximena Ruiz1*, and Martha Almanza1 1Universidad del Cauca, Facultad de Ciencias Agrarias, 190003 Popayán, Cauca, Colombia. *Corresponding author ([email protected]). Received: 24 March 2018; Accepted: 6 September 2018; doi:10.4067/S0718-58392018000400569 ABSTRACT Improvement programs depend on characterizing genetic resources, this process being the fundamental basis for determining the diversity and genetic divergence of such resources and thereby enabling a rigorous, efficient selection of the parentals that, through hybridization, will go on to enhance heterosis. The aim was to use the resulting hybrids to improve population mean with respect to genetic parameters used for the qualitative and quantitative traits that affect commercial natural silk production. Bombyx mori L. is a domesticated insect of global economic importance, mainly due to the production of natural silk but also for its relevance in rural agro-industry in tropical and subtropical regions. Non-textile uses currently being developed are also to the fore. These relate to such fields as science and academia, biomedicine, biotechnology, the pharmacological industry and cosmetics. With this in mind, the aim of the current article was to provide a general context for sericulture and in so doing give an overview of the silk production scenario nationally and go on to describe the importance of genetic diversity to silkworm breeding programs and to demonstrate how genetic drift, inbreeding, and artificial selection contribute to loss of genetic diversity inB. mori. Key words: Cauca, genetic divergence, genetic improvement, sericulture. INTRODUCTION The silkworm (Bombyx mori L.) is an insect of great economic importance, bred in seasonal and tropical areas (Tazima, 1978).
