Ten 1,2,4-thiadiazolidines were synthesized and screened for their anti-inflammatory and analgesic activities. Butyl isothiocyanate was used as a starting material. Several compounds showed significant anti-inflammatory and analgesic activities. The unsubstituted and o-methyl, p-acetoxy and o-chloro substituted compounds were found to be more potent anti-inflammatory and analgesic agents than the other compounds.

A field study on self trap cropping system in controlling tukra mealy bug Maconellicoccus hirsutus Green) incidence on mulberry (Morus spp.; V-1 variety; $3'{\times}3'$ spacing) gardens was undertaken in selected sericulture farmers' mulberry gardens of Pydeti village (Parigi Mandal, Anantapur District, Andhra Pradesh, India). The study was conducted for three years (2004, 2005 and 2006). Four treatments (T0; control/no treatment, T1; self trap cropping rows with 10 row interval, T2; self trap cropping rows with 10 row interval and treating these rows only with 0.5% neem oil emulsion and T3; self trap cropping rows with 10 rows intervals and treating all the mulberry rows including self trap cropping rows with 0.5% neem oil emulsion) were considered. The results indicated that the incidence increased in T0 and T1 while the same suppressed in T2 and T3. The suppression (%) of tukra incidence between T2 and T3 was not significant. Hence, T2 only was recommended to farmers as its economical viable practice. The results are discussed based on the importance of tukra, its suppression and cost of treatment.

<P>The independent isomeric yield ratios of Zr-89g,Zr-m from the Zr-nat(,xn) reactions and those of Mo-91g,Mo- m and Nb-97g,Nb-m from the Mo-nat(,x) reactions with the bremsstrahlung end-point energy of 45-70 MeV were determined by an off-line -ray spectrometric technique using the 100 MeV electron linac at the Pohang Accelerator Laboratory, Korea. The isomeric yield ratios of Zr-89g,Zr-m and Nb-97g,Nb-m from the Zr-nat(, xn) and Mo-nat(,x) reactions at the bremsstrahlung end-point energy of 16MeV were also determined by the same technique using the 20MeV electron linac at Helmholtz-Zentrum Dresden-Rossendorf, Germany. The measured isomeric yield ratios of Zr-89g,Zr-m, Mo-91g,Mo-m, and Nb-97g,Nb-m were compared with literature data to examine the role of the Giant Dipole Resonance (GDR). The isomeric yield ratios of the Zr-89g,Zr-m, Mo-91g,Mo-m, and Nb-97g,Nb-m from the above reactions were also calculated by using the computer code TALYS 1.6 and compared with the experimental data to examine the validity of the theoretical model for independent isomeric yield ratio calculations.</P>

Two hundred and forty post-larvae (PL) of fresh water prawn, Macrobrachium rosenbergii were distributed in eight treatment groups with three replicates each. Eight experimental diets were prepared by using squilla (Orato squilla nepa), squid (Sepia pharonis) and clam (katelysia opima) alone or in different combination as source of animal protein and compared to a control diet containing fish meal. Total crude protein content for all dietary treatments was around 32%. Total protein content of fish meal was replaced by an equal amount of protein from different animal protein sources on isonitrogenous basis. Diets were fed at 5% of the body weight of post-larvae twice daily. The experiment was conducted for a period of 60 days. It was found that all the above three protein sources could be used by completely replacing fishmeal except clam meal at higher level of inclusion (26%). A combination of squid and squilla meal at 14% each in the diet increased the growth performance of PL significantly (p<0.05) in terms of Specific growth rate (SGR) % (5.17), FCR (2.12) and PER (1.51). Squilla meal can be used to the maximum level of 38% without any growth depression.
Implications of Temperature and Humidity on Pupation Patterns in the Silkworm, Bombyx mori L.

The implications of temperature (25,30 and 35$^{\circ}C$) and relative humidity (60, 70 and 80%) on the pupation patterns were studied in the silkworm, Bombyx mori L. Larvae of two pure silkworm breeds, Pure Mysore (PM) and NB4D2 and their hybrid, PM ${\times}4 NB4D2 were reared under experimental conditions under natural day photoperiodic (LD 12: 12) condition. The three developmental marker events viz., larval ripening, pharate pupal formation and pupal formation occurred at or around the beginning of the photo-phase. The computed of mean vector (equation omitted), based on the circular statistics, also confirmed the above. However, the length of mean vector, r and the mean vector angular variance, s varied according to temperature and humidity conditions imposed; the variations being non-significant. Extreme temperature and humidity conditions, however, resulted in reduction in pupation rate (%) for PM and PM ${\times}4 NB4D2. On the other hand, in NB4D2 pupation percentage reduced below the economic level. The temperature and humidity together seems to exert synergic impact on the pupation rate at least in the silkworm Bombyx mori, L.
