Chlorophyllin Bait Formulation and Exposure to Different Spectrum of Visible Light on the Reproduction of Infected/Uninfected Snail Lymnaea acuminata

Table 4

Effect of sublethal (40% and 80% of 24 h LC₅₀) chlorophyllin in bait containing serine and starch (in red light/sunlight) on the fecundity, hatchability, and survival of the uninfected snails L. acuminata eggs.

Each value is mean ± S.E of six replicates. Each replicate represents the eggs laid by the group of 20 snails. Significant () difference was noted when Student’s -test was applied to treated and control groups.
⁺Product moment correlation coefficient showed that there was significant () negative correlation in between exposure period and fecundity of snail L. acuminata. (—) shows no dose; (0) shows no fecundity, hatchability, and survivability.
