Enzyme activity was measured in 10-mm path length cuvette using incubation mixtures and change in optical density was recorded. &lt;strong&gt;Results:&lt;/strong&gt; Sublethal 4 h LC&lt;sub&gt;50&lt;/sub&gt; 40% and 80% of these formulations in sunlight and laboratory conditions caused no significant change in AChE activity in the nervous tissue of host snail. It was noted that sublethal &lt;em&gt;in vivo&lt;/em&gt; 8 h exposure to 40% and 80% of 4 h LC&lt;sub&gt;50&lt;/sub&gt; of single and binary combination of CHL+FCU, CHL and FCU significantly altered the AChE and cytochrome oxidase activity in the cercaria larvae. Binary combinations of CHL+FCU in sunlight were more effective in inhibiting both the enzymes. &lt;strong&gt;Conclusion:&lt;/strong&gt; The present study reported that enzymes AChE and cytochrome oxidase were inhibited by chlorophyllin formulations and thus causing the larval death inside the snail body without affecting the snail itself which is an important bioindicator of aquatic ecosytem.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">768</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Dinesh Kumar Singh&lt;sup&gt;*&lt;/sup&gt;, Divya Jyoti Singh&lt;/strong&gt;&lt;/p&gt;

These snails were treated with different concentrations of chlorophyllin. Chlorophyll was extracted from spinach with the help of macerated leaves and kept for 2 h in 100% ethanol at 55&amp;ordm;C. &lt;strong&gt;Results:&lt;/strong&gt; The results of the experiment showed that the photodynamically active chlorophyllin, at low concentration was able to kill the snails under exposure of solar radiation in summer season instead of winter season. In winter, extracted chlorophyllin toxicity against &lt;em&gt;L.&lt;/em&gt; &lt;em&gt;acuminata&lt;/em&gt; in sunlight (96 h LC&lt;sub&gt;50&lt;/sub&gt; 91.82 mg L&lt;sup&gt;-1&lt;/sup&gt;) /laboratory condition (96 h LC&lt;sub&gt;50&lt;/sub&gt; 921.93 mg L&lt;sup&gt;-1&lt;/sup&gt;) was less than pure chlorophyllin in sunlight (96 h LC&lt;sub&gt;50&lt;/sub&gt; 12.05 mg L&lt;sup&gt;-1&lt;/sup&gt;) /laboratory condition (96 h LC&lt;sub&gt;50&lt;/sub&gt;19.22 mg L&lt;sup&gt;-1&lt;/sup&gt;), respectively. In summer, pure chlorophyllin was more toxic in sunlight (96 h LC&lt;sub&gt;50&lt;/sub&gt; 3.90 mg L&lt;sup&gt;-1&lt;/sup&gt;) than laboratory condition (96 h LC&lt;sub&gt;50&lt;/sub&gt; 7.18 mg L&lt;sup&gt;-1&lt;/sup&gt;). Pure chlorophyllin is more than five times toxic than synthetic molluscicides. Treatment of chlorophyllin caused no toxic effect against the fish (&lt;em&gt;Colisa fasciatus&lt;/em&gt;). The result presented in this paper is found very beneficial and ecologically safe, as a photodynamic substance chlorophyllin, which found in every green plant. &lt;strong&gt;Conclusion:&lt;/strong&gt; Phytotherapy of snails by photodynamic water soluble chlorophyllin to control fasciolosis can be used as potent molluscicides with low cost and easily biodegradable.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">594</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Kavita Singh, DK Singh and Vinay Kumar Singh&lt;sup&gt;* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
