Abstract: ARAPE, JAMAICA OBISCURO and HERNANDEZ, NINALYN NUNEZ “Field Evaluation of Fenos 480SC against Tomato fruit worms, Helicoverpa armigera (Hubner) Noctuidae: Lepidoptera” Undergraduate Thesis. Bachelor of Science in Biology, Cavite State University, Indang Cavite. April 2008. Dr. Josefina R.Rint. The study was conducted to evaluate the effectiveness, of Fenos 480SC on the insect pests and the level of damage in tomatoes; to evaluate the efficacy of Fenos 480S insecticide against fruit worms and other lepidopterous insects in tomato; to determine the most effective dose rate of Fenos 480SC against the target insect pests; and to compare the efficacy of different dose rates of Fenos 480SC with Selecron against insect pests of tomato. A barren area in Daine, Indang Cavite was used in the study. Five treatments were used, T1- untreated plants, T2- treatment plants with 0.8g Fenos 480SC, T3- treatment plants with 1.6g Fenos 480SC, T4- treatment plants with 2.4g Fenos 480SC and T5- treatment plants with 32ml Selecron 500SC. In terms of effectiveness of pesticides against fruit worms before treatments, T2, (0.8g Fenos 480 SC) and T4, (2.4g Fenos) were the most effective, while among the after treatments TS, (Selecron) was the most effective. For the mean count of fruits before treatment, T2, (0.8g Fenos 480 SC) was th highest with 1281.8 fruits were in after treatment, T1, (untreated plants) was the highest. For total harvested fruits, untreated plants has the highest fruits harvested compared to all treatments with pesticides. The untreated plants had the highest rate of fruit worms infestation. All the plant treated with insecticides were able to control the fruits by 98.99 %. Harvest of fruits was not affected by the treatment of insecticides. Fenos 480 SC at 1.6g dosages had the highest weight of fruits from fruit worm pests.

In terms of effectiveness of pesticides against fruit worms before treatments, T2, (0.8g Fenos 480 SC) and T4, (2.4g Fenos) were the most effective, while among the after treatments TS, (Selecron) was the most effective.

For total harvested fruits, untreated plants has the highest fruits harvested compared to all treatments with pesticides.

The untreated plants had the highest rate of fruit worms infestation. All the plant treated with insecticides were able to control the fruits by 98.99 %. Harvest of fruits was not affected by the treatment of insecticides. Fenos 480 SC at 1.6g dosages had the highest weight of fruits from fruit worm pests.
