DR.BALRAJ SINGH PARMAR Abstract:

Abstract: An insect handling device comprises of a rigid platform provided with at least two holes, the first of the
Novel supcrabsorbent cellulosic hydrogels obtained by a method which comprises simultaneous grafting at least two holes being fitted with a guiding means, said guiding means is projected up the platform,
and chemical crosslinking of cthylenically unsaturated monomers onto cellulose ether backbones in the plurality of ridges or protrusions are provided on top of platform or exterior of the lid of inner container
presence of free radical initiator of chemical or non-chemical origin in a homogeneous phase in polar for maintaining gap there between to enable flow air and the insect dust or scales to be collected, the at
solvent/s at a temperature of 15-100° C, reaction time from instantaneous to 24 hours to achieve the least second hole of said at least two holes is connected in an air tight manner with a vacuum generating
gel point, and an inert or ambient environment. Lithylenically unsaturated monomers herein include means, an insect collecting inner container being placed over the said platform, a hole either in a lid or in a
acrylic monomers preferably containing carboxamide groups and the like; the cellulose ether backbone wall of the said inner container accommodates the projected end of the guiding means, the said wall and
comprising any of the carboxyalkyl cellulose, hydroxyalkyl cellulose or the like; the chemical initiator such the lid of the inner container having perforations, the size of perforations being smaller than that of the
as water soluble persulfates of ammonium, potassium, sodium or other alkali metals, ammonium cerric insect being collected, an outer container with open bottom and closed from the top made from a material
nitrate, peroxides such as hydrogen peroxide or organic peroxides, water soluble azo compounds such as able to withstand vacuum and impermeable to air being fitted in an air tight manner on to the platform, an
2,2’-azobis-(2-amidinopropane) and the like, used either alone or in combination with co-initiator; the non- insect collecting tube, one end of said insect collecting tube being fitted with a nozzle for collecting insects
chemical initiator such as electromagnetic radiations; the chemical crosslinking being carried out in the and the other end being passed through the guiding means slightly projecting out the said guiding means
presence of a bisacrylamide. The hydrogels obtained herein possess water absorption potential of at least and inside of the inner container.
15000% on mass-by-mass basis, while retaining structure and fluid absorption properties at temperatures
upto 90° C.
