Androgenesis in silkworm acquires a special significance as along with combined applications of other breeding strategies like parthenogenesis and cloning, it may serve as n valuable tool for sex control in sericulture as well as selection and production of bisexual homozygous androgenetic lines. Production of hybrid silkworm yielding high proportion of male larvae is of immense use to silk industry (Strunnikov, 1975, 1983). In this review, an attempt has been made to assimilate the works carried out on androgenesis, different techniques of induction towards androgenetic development and its role in silkworm breeding.

Fifth instar larvae of the new bivoltine hybrid (CSR2
CSR5) were reared under different temperature and humidity viz.,
5% R.H (T1),
5% R.H (T2-Optimum),
5 R.H (T3) and
5% R.H (T4). The cocoon yield, cocoon characters and disease incidence were studied in normal (non infectious source, i.e control) rearing as well as in 1% infectious source of rearing. The results indicated that V instar larval duration was prolonged and cocoon weight was improved in T1. ERR and shell ratio were significantly improved and disease incidence was minimised in T2. Further significant difference was observed among the treatments with regard to spread of diseases.

In India, mulberry (Morus spp.), the sole food plant of the silkworm, Bombyx mori (Linn.), is prone to infestation by the pink mealybug, Maconellicoccus hirsutus (Green). Infestation by this pest causes apical shoot malformation, popularly known as 'tukra'. Occurrence of tukra causes an appreciable reduction in leaf yield and quality, leading to low silkworm cocoon productivity. For management of M. hirsutus (Tukra), an IPM package comprising mechanical, chemical and biological measures was demonstrated in the mulberry gardens of five Government Silk Farms in Mysore District (Karnataka, India) during 1995-96. A suppression of 76.0% in tukra incidence and 90.19% in mealybug population was recorded by employ the IPM package which led to an estimated 4,000 kg recovery in leaf yield/ha/year. The impact of IPM package in the management of M. hirsutus, the role of biocontrol agent (Cryptolaemus montrouzieri Muls.) in pest suppression and the cost-benefit analysis of the IPM package are discussed.

A cDNA encoding a cathepsin D homologue was cloned from a cDNA library of the mulberry longicorn beetle, Apriona germari. Sequence analysis of the cDNA encoding the cathepsin D homologue of A. germari revealed that the 1,158 bp cDNA has an open reading frame of 386 amino acid residues. The deduced protein sequence of the A. germari cathepsin D homologue shows high homology with cathepsin D in insects, Aedes aegypti (68.2% amino acid similarity) and Drosophila melanogaster (67.2% amino acid similarity). Two aspartic residues and six cystein residues in the A. germari cathepsin D homologue are present at identical locations in all of the other catepsins D. Unlike cathepsins D in two insect species, A. gemari cathepsin D homologue appears to have two putative glycosylation sites, rather than one. Phylogenetic analysis revealed the A. germari cathepsin D homologue is more closely related to insect cathepsins D than to the other animal cathepsins D. Northern blot analysis suggests that A. germari cathepsin D homologue gene is expressed in most if not all, body tissues.

With an objective of evolving quantitatively and qualitatively superior bivoltine breeds/hybrids of silkworm Bombyx mori L. for tropical conditions, breeding work was initiated in Central Sericultural Research and Training Institute, Mysore during 1992 by utilizing two Japanese hybrids namely BNl8
BCS25 and Shunrei
Shogetsu along with Indian evolved breed, KA. The breed CSR12 which is characterized with sex-limited larval marking and white oval cocoons was evolved from the Japanese hybrid BNl8
BCS25 by crossing with KA, while the breed CSR6 which is characterized with normal marking (marked larvae) and white dumbbell cocoons was extracted from the Japanese commercial hybrid Shunrei
Shogetsu through continuous inbreeding coupled with selection. After fixation, these breeds along with other newly evolved breeds were subjected to hybrid study under optimum environmental conditions in the laboratory for expression of full potential of the genotypes. These hybrids were evaluated by Multiple Trait Evaluation Index (Mano et al., 1993). The hybrid CSR12
CSR6 was selected based multiple trait evaluation index value. The hybrid CSR12
CSR6 recorded survival of 96.0%, shell weight of 50.0 cg, shell ratio of 24.3%, raw silk percentage of 19.6, filament length of 1,216 m, boil off loss of 22.4% and renditta of 5.1. On the other hand, the control hybrid (KA
NB4D2) has recorded survival of 90.6%, shell weight of 42.1 cg, shell ratio of 20.4%, raw silk percentage of 15.9, filament length of 999 m, boil off loss of 24.8% and renditta of 6.3. The hybrid CSR12
CSR6 was authorized during 1997 by Central Silk Board, Government of India for commercial exploitation during favourable months based on national level race authorization test.

Effect of topical application with 10, 20 and 30
/ml testosterone propionate and estradiol -17
on the fourth and fifth instar bivoltine NB18 silkworm larvae Bombyx mori, on the glycogen and protein contents of the Fat body and trehalose and protein contents of the haemolymph has been studied. Glycogen content of the fat body was significantly decreased in both testosterone propionate and estradiol -17
treatment groups except in the group treated with 30
testosterone propionate where the increase was not significant when compared with those of carrier controls. The increase/decrease in haemolymph trehalose content did not show any significant difference in all the treated groups. Protein content of the fat body significantly increased in 10 and 20 mg testosterone propionate and estradiol -l7
treated groups but in 30 mg treated groups the increase was not significant when compared with those of carrier controls. There was no significant change in the haemolymph protein content in all the testosterone propionate and estradiol -17
treated groups except in group treated with 10
where it showed a significant decrease when compared with that of carrier control.

International Journal of Industrial Entomology, volume 3, issue 2, 2001, Pages 153~155
Eight new three-way cross heterozygotic hybrid genotypes of the mulberry silkworm Bombyx mori, resulted from hybridization of multivoltine as female and bivoltine Fl hybrid as male component, have been evaluated for the cumulative effect of nine traits of commercial economic importance with the objective of selecting out the most prospective ones for their exploitation as an intermediate technology during unfavorable season. Five of them namely, G(P5
NBl8) (E.I. =57.23); S(NB18
P5) (E.I. : 55.48); S(P5
NBl8) (E.I. = 52.44); S(KBN
B7) (E.I. = 50.42) and S(NB7
KB) (E.I. : 50.16) have scored higher values of the Evaluation Index (E.I.) and could be selected in the same order for exploitation during unfavorable seasons in tropical climates.

Goudar, K.S. ; Kaliwal, B.B. ;
International Journal of Industrial Entomology, volume 3, issue 2, 2001, Pages 157~162
The effect of topical application with naphthoxyacetic acid on economic parameters was analyzed following treatment of fifth instar larvae. Larvae treated during the fifth instar showed significant increase in larval weight along with other enhanced larval, cocoon and adult parameters. The larval period was significantly shortened in all the treated groups with increased cocoon and shell weights in male and shell weight in female in 400
/ml treated group and filament length in all the treated groups. Fecundity increased significantly in dose dependent manner in all the treated groups, when compared to that of the carrier control group. This suggests that naphthoxyacetic acid, in addition to affecting larval growth, also affect silk production and reproductive performance.

We isolated and sequenced a cDNA clone corresponding to apolipophorin-III (apoLp-III) from the fall webworm, Hyphantria cunea. The cDNA for apoLp-III codes fer a 187-residue protein (561 bp) with a predicted molecular mass of 20 kDa. The calculated isoelectric point is 8.76. Multiple alignment analysis of the amino acid sequence revealed that H. cunea apoLp-III is most similar to that of Spodoptera litura (71.5% identity), followed by that of Manduca sexta (69.7% identity). They share five amphipathic
-helices that are proposed to play a critical role in the binding of apoLp-III to lipophorin.

A synthetic juvenoid, R394 (Ethyl 9-cyclohexyl-3, 7-dimethyl-2, 4-nonadienoate) which is known to be a strong pest control agent was administered to silkworm, Bombyx mori L. in minute quantity for improving the silk yield. Based on the result of an earlier preliminary screening, three concentrations of the compound, viz., 0.1563, 0.3125, 31.25 nl/ml were prepared in the form of an emulsion and administered topically as a single dose, to separate batches of
instar silkworm at 24, 48, 72 and 96 hrs to determine the required concentration and critical time of application for an economically favourable response. Two popular commercial silkworm hybrids, PM
bivoltine) and KA
bivoltine) were subjected to the experiment. The medium and absolute control were maintained in parallel to compare the results. The results showed that 0.3125 nl/ml was the best concentration of the compound and 72 hrs of
instar was the most favourable age for its administration to get the maximum improvement in the commercial traits. The possible role of exogenous juvenoids in eliciting favourable response in silkworm which ultimately leads to improvement in the commercial traits is discussed.

International Journal of Industrial Entomology, volume 3, issue 2, 2001, Pages 177~185
This study has been carried out to determine localization of Manduca sexta allatotropin (Mas-AT) neuropeptide in developing ventral nerve cord of the silk moth Bombyx mori with polyclonal antisera against Mas-AT. Suboesophageal ganglion (SOG) of the second to fifth instar larvae and 3-day-old pupae showed two to ten Mas-AT-immunoreactive (Mas-AT-IR) cell bodies. There were two to three pairs of labeled cell bodies in each thoracic ganglion (TG) from third instar larvae to adults, with the exception of TG from prepupae. One pair of labeled cell bodies was localized in each abdominal ganglion (AG) 1 to 6 from third instar larvae to 3-day-old pupae, whereas in 5-day-old pupae to adults there was one pair in a similar location of AG 1 to 5. The seventh neuromeres of terminal abdominal ganglia (TAG) from third instar Iarvae to 3- day-old pupae contained four labeled large cell bodies. In each of AG 1 to 7, these cell bodies showed similar allatotropin-immunoreactivity in appearance. Some labeled axons, projected from Mas-AT-lR cells in each of those AG, were extended to the nerves N 1 and N 2.

Inheritance pattern of resistance to Bombyx mori nuclear polyhedrosis virus (BmNPV) was studied in an Indian silkworm stock TX by single back-cross test method. The resistant parent ［TX］, susceptible parent ［HM］, their Fl, F2, and Fl progeny back-crossed to TX [BC(R)] and HM [BC(S)] were inoculated per os with a fixed concentration of BmNPV(
) on the first day of second stadium. The cumulative mortality was recorded until day
post-inoculation. The results show that the resistance to BmNPV in TX fellow mono Mendelian inheritance pattern. The resistance dominated over the susceptibility at Fl. At F2, the resistant and susceptible offspring segregated in 3:1 ratio whereas at BC(S), the resistant and susceptible offspring segregated in 1:1 ratio. The response of BC(R) was more or less like the resistant parent TX which confirms the involvement of a major dominant gene conferring resistance to BmNPV in TX. The possible mechanism of inheritance of resistance in TX is discussed.
