We included the fitness component test, as an indicative of snail’s vitality and energetic condition, measuring their crawling mean speed and the mean heart bit rate of new born baby snails that have similar body weights. As far as prolificacy, the witness enclosure batches accounted for 100 ±5.72 while the batches in experimental enclosures accounted for 248.00 ☘.29 and 140.00 ±5.10 respectively. The adult Helix aspersa Muller snail populations in the witness lots display a survival mean rate under extreme heat wave and drought conditions of just 6.50 ± 1.29 while the population in the experimental lots with Armoracia rusticana and Symphytum officinale presented higher survival mean rate of 14.00 ☐.82 and 16.75 ☑.50 respectively. The experiments took place in town of Băişoara, Cluj County, Romania in the June – August 2010 interval. We investigated the influence of Armoracia rusticana and Symphytum officinale upon the development of one of the most farmed and consumed terrestrial snails Helix aspersa Muller (Cornu aspersum), an excellent animal protein source for humans. Some plants have toxic properties to some animal species whereas to others they represent a priority in herbivore’s diet. Abstract: Many perennial plants are often huge biomass producers capable of capturing the solar energy and producing valuable nutrients, plants that represent food source for many herbivores.
