NEEMONA (Insecticide)
NEEMONA (Azadirachtin 1% Concentrate)
Azadirachtin, a complex tetranortriterpenoid limonoid from the neem seeds, is the main component responsible for the toxic effects in insects. Such effects include primary and secondary antifeedancy, growth reduction, increased mortality, abnormal and delayed moults and sterility effects. Such wide-ranging biological effects in insects come about in two different ways: firstly by direct effects of azadirachtin on cells and tissues and secondly by indirect effects exerted via the endocrine system following direct effects in the neuroendocrine tissues themselves. Azadirachtin stimulates specific 'deterrent' cells in chemoreceptors and also blocks the firing of 'sugar' receptor cells, which normally stimulate feeding. This results in an inhibition of feeding, culminating in starvation and death of these species by feeding deterrence alone.
