Goals / Objectives
To evaluate the effect of Azadirachtin (Neem) extract on: (i) Life cycles of five insect pest: A. Vittatum; P. rapae; E. verivestis; H. platura; and C. tenellus. (ii) Yield of turnip, cabbage, beans, cucumber and squash. (iii) Powdery mildew.
Project Methods
Neem extract is an environmentally safe biocyte. Azadirachtin, the active ingredient of Neem, is capable of foiling even some of the most voracious vegetable pests. Most importantly, it does not leave any poisonous residue as its conventional organic counterparts do.

Progress 10/01/99 to 09/30/04

Outputs
This project has terminated due to death and the resignation of key personnel. All data are being analyzed for publication.

Impacts
Biological controls of insects will be much more environmentally acceptable.

Progress 10/01/01 to 09/30/02

Outputs
Different solvents were tested as vehicles of extracting the active compound, azadirachtin, from the tissue of the neem plant. These solutions were then tested on selected species of insects. Two manuscripts have been prepared for publication as a result of this study: (1) Insecticidal and Antifeedant Activities of Neem Seed and Callus Extract Against Larvae of Manduca sexta; and (2) Use of Azadirachtin Extract as a Broad Spectrum Pesticide for Vegetables.

Impacts
By using biologically-friendly means of pest control, both producers and consumers will benefit. Cost-effective and safe means of controlling insect pests will provide cheaper and safer sources of food and will protect the environment by reducing the amount of chemical pesticides now being used.

Progress 10/01/00 to 09/30/01

Outputs
Neem (Azadirachtin indica) plants are continuing to be grown. The research received a severe set-back due to the untimely death of one of the research team members. Different solvents are being tested as vehicles of extracting the active compound, azadirachtin. These solutions will then be tested on selected species of insects.

Impacts
The findings of this research would provide alternatives for organic pesticides to both farmers and home owners. Use of biological controls are much more environment-friendly and would also be cost effective.

Progress 10/01/99 to 09/30/00

Outputs
Seeds of Azadirachta indica were obtained from USDA/ARS and four seedlings, after having been successfully germinated in growth chanber, are in 20-inches dia plastic planters. These transplants are expected to be about 10 feet in height and would provide enough foliage as a source of azadirachtin by Spring 2001. Experiments on Pieris rapae (Imorted Cabbage Worm), Epilanchna verivetis (Mexican Bean Beetle) and Acalymma vittatum (Striped Cucumber Beetle) would start sometime in April 2001 after these pests are made available from field plots.

Impacts
The findings of this research would provide alternatives for organic pesticides. Biological methods are environmentally safe and cost saving.
