One of the advantages of studying tropical agriculture on the Big Island is the opportunity we have as students to see a diversity of farming methods, all of which play a role in the island economy and community.

Following the graduation of several key members, the Agriculture Club at the University of Hawai‘i at Hilo has had a few changes in leadership starting in the fall of 2014. Among the new officers are Michael Sthreshley as president, and Miguel Bravo Escobar as vice president. Lukas Kambic and Rachel Gorenflo continue as treasurer and secretary, respectively.

The “Ag” Club has been working to establish new relations with the UH Hilo Farm Laboratory faculty. In previous semesters the club has had limited involvement with the university farm. Since the club represents our College of Agriculture, Forestry and Natural Resource Management and aims to open up opportunities to students, we wish to learn more and gain further experience with agriculture and related topics utilizing college’s facilities.

Each semester, the class helps clean up a fruit and vegetable garden at the Malia Puka O Kalani Catholic Church in Keaukaha.

Have you heard about the sustainable agriculture course (Ag230) at the University of Hawai‘i at Hilo? This course offers community outreach, sustainable practices, and the experience of designing your very own sustainable garden. The course is taught by Norman Arancon, associate professor of horticulture. Students in the course are separated into groups and are assigned different areas on the UH Hilo campus, where they get to plant, grow, and harvest their own food.

This article will give you an insight on one of the field trips taken in the course last fall. In this community outreach field trip, the class helped clean up a fruit and vegetable garden at the Malia Puka O Kalani Catholic Church in Keaukaha.

Management options should be carefully considered since some treatments have the potential to be more damaging than the pests themselves.

Vegetable Leafminer: Liriomyza sativae (Blanchard)

We’ve all seen them, white trails meandering across leaves in your  garden. Most of us know leafminers are the culprits, but what is a leafminer? When these trails are observed they are usually empty, as if they’ve been traced by some phantom pest.

In mid-September, I observed what I believed to be leafminer damage on the foliage of hydroponic tomato plants in the hydroponic greenhouse, at the University of Hawaii at Hilo Farm Laboratory in Panaewa. I came to the immediate conclusion that the damage was done by leafminers because of the conspicuous grey, serpentine lines on the leaves of the plants, a symptom specific to all leafminer species.
