Experiment Title Evaluation of various insecticides as lure toxicant against fruit fly in mango orchard
Research Type Departmental Trail
Experiment Background South Gujarat is leading in fruits and vegetable production in Gujarat state. Three districts viz., Surat, Navsari and Valsad are included in agri-export zone for fruits and vegetables, which require quality production. Fruit flies are the major constraint which ravages considerable loss in terms of quality and production. Moreover, these flies are good fliers and thereby their spread is also very high and hence area wide adoption of management strategy can only be useful against the flies. Fruit flies, although a serious pest, are largely uncontrolled or controlled by cover sprays of insecticides which are undesirable in fruits and vegetables. Navsari Agricultural University has designed and commercialized an eco-friendly, economical and easily adoptable fruit fly trap popularly known as "Nauroji-Stonehouse Fruit Fly Trap" (Developed by Dr. Z. P. Patel, Hon. Vice chancellor, NAU, Navsari) through Male Annihilation Technique (MAT). Since many years this trap is working very good on “attract & kill” mechanism when it installed in any fruit or cucurbit vegetable orchards. The key ingredients of solution used in this trap are ethyl alcohol, methyl eugenol and DDVP as an insecticide at the ratio of (6:4:1), respectively. Further the insecticide (DDVP) used in the trap which act as killing agent banned by the Central Insecticides Board and Registration Committee, Government of India with effect from the 31st December, 2020 [As per document of list of pesticides which are banned, refused registration and restricted in use (As on 01.01.2021) (Pesticides Banned for manufacture, import and use: Sr. No. 14 Dichlorovos (Vide S.O. 3951(E), dated 08.08.2018)] So, there is urgent need to find out the new and effective insecticide which can be used for lure toxicant as replacement chemical. Keeping in view to the importance of "Nauroji-Stonehouse Fruit Fly Trap" for monitoring and management of fruit fly, present study is being proposed for the evaluation of different insecticides as lure toxicant for the management of fruit fly in mango orchard.

Methodology:

This study will be carried out in the mango orchard of NMCA College farm, NAU campus, Navsari. The experiment will be carried out by installation of trap at marble size fruit stage starting from March to June. Lure baited Nauroji Stonehouse Fruit Fly traps treated with different insecticides treatments @ 4 traps per treatment will be installed in the mango orchard. Data regarding numbers of male flies catches will be recorded fortnightly and brought to the laboratory, counted to know the efficacy of insecticidal treatments.

The details of the insecticides to be used are below.

Sr. No.

Name of insecticide

1.

Malathion 50 EC

2.

Spinosad 45 SC

3.

Lambda cyhalothrin 5 EC

4.

Decamethrin 11 EC

5.

Fenpropathrin 10 EC

6.

Profenofos 40 EC + Cypermethrin 4 EC

7.

Control (without lure toxicant)

Procedure for the preparation of ME mixture:

For preparation of lures, Iso-propyl alcohol or methanol, methyl eugenol and test insecticide(s) will be used in the ratio of 6:4:1. Each 5 x 5 x 1.2 cm size plywood block nailed with plastic string requires approximately 4ml of solution. Accordingly based on the number of lures required, required quantity of solution will be prepared in a glass bottle with lid facility. The plywood block will be soaked in the prepared solution for 24 hours for complete absorption of solution. The container will be closed air tight to avoid evaporation of solution. After 24 hours, the individual treated plywood block lure will be wrapped with plastic for storage and future use or directly use in the trap for installation. The proper care will be taken to wear face mask and gloves while preparation and handling of para pheromone lures.
