| SPECTRUM
|
Highly active against 1st / IInd / IIIrd
instar larvae of various mosquito species
e.g. Culex, Anopheles, Culisetta,
Psorophora, Uranotaenia, Mansonia,
vectors of Malaria, Filaria, Japanese
Encephalitis, Dengue fever and Nuisance
mosquitoes. It is also active against
Phlebotomus argentipes vector
of kala-Azar. |
|
| |
|
| MODE
OF ACTION : |
Sphericide
acts on host larvae through its parasproal crystal
delta endotoxin and bacterial spores, causing
starvation, paralysis and septicemia of larval
bodies ultimately resulting death of larval bodies.The
endotoxin acts on midgut epithelium causing disintegration
of gut wall, cessation of feeding activity, starvation
and leakage of gut contents into haemolymph and
body cavity of the larvae leading to general paralysis
of larval body. The spores germinate to form bacterial
cells that multiply in the larval gut and body
causing septicemia. Surviving larvae , if any,
because of consuming sublethal doses, lead to
under developed / deformed pupae / adults unable
to form the progenies. |

| FURTHER
INFORMATIONS |
Sphericide
results in sharp and continuous decline of larval
populations (90-100%) within 6-24 hrs. of application,
in various habitats and ecologically different
sites including drains, water streams. Sewerage
tanks, water coolers, cooling towers, fountains,
construction sites, industrial scraps, rice fields,
septic tanks, ditches, pools and marshy ponds,
etc. This results in decline of adult mosquitoes,
slide positivity rates and parsitological indices.
It causes kill of mosquito larvae even in highly
polluted, muddy, marshy waters where its persistence
continues for 4-8 weeks thus avoiding frequent
application required in case of chemical larvicides
. It is a product of choice for use against An.
Sundaicus, a malaria vector prevalent in marshy/saline
waters in coastal / inland areas and against
Culex quinquefasciatus, C. tritaeniorhynchus
and C. vishnui, vectors of filaria and
Japanese encephalitis prevalent in rice
fields.
