AM20090321.002 Fly Tunneling in Stem of Lettuce

Posted by on 21 Mar 2009 | Tagged as: Uncategorized


Maggots were found tunneling in stems of lettuce growing in an aquaponics operation. Four small black flies (BL=2.1mm) were reared out and identified as Melanagromyza splendida, AGROMYZIDAE. This fly was first collected on Guam in 1986. According to Schreiner 1991:

“This agromyzid fly is an internal borer in the stems and midribs of large leaves (Spencer 1973). Previously, it was known to attack Compositae and Umbelliferae, but on Guam it has been reared from tomato leaves and from midribs of mizuna, an Asian Brassica variety. The native distribution of this species is tropical and subtropical Americas, but it has been present in Hawaii for many years.”

Ron Mau lists M. splendida as a pest of lettuce in his Knowledge Master website for crop pests in Hawaii, and uses “safflower stemminer” as a common name. According to Spencer 1973:

“This species has been reared from lettuce in Hawaii but significant damage has not been reported.”

Bugs in Outgoing Cargo

Posted by on 11 Mar 2009 | Tagged as: Uncategorized

These bugs belong to the family Aradidae, the “flat bugs”.  Aradids feed on fungus and are not considered to be agricultural pests.

These were found on wood material (pallets etc.) at Andersen Airforce Base by USDA APHIS inspectors. This material came from the Naval Base and it was being shipped to Hawaii. The wood also contained termites and it was fumigated before leaving Guam.

Thrips on Culantro

Posted by on 08 Feb 2009 | Tagged as: Uncategorized

Small immature thips feeding on culantro (Eryngium foetidum) leaves.  Body length of largest is about 0.8 mm.  They feed adjacent to the midriff and cause significant silvering.  Many carried fecal matter on their raised abdomen.  No adults were collected.

My guess is that this is the greenhouse thrips, Heliothrips haemorrhoidalis (Bouché).  This species was reported from Guam by D. Nafus in An Insect Survey of the Federated Satates of Micronesia and Palau, SPC Technical Paper No. 210. 1997.

Guam- The Department of Agriculture was the center of attention during this afternoon’s orientation hearing at the legislature. Committee on Rules and Natural Resources Chair Rory Respicio says he wants to help the agency achieve its mandates.
Some of the issues that were addressed during the hearing included the handling of the Guam Greyhounds, the control of the invasive species like the Rhinoceros beetle, and the status of the new indigenous fishing rights law. Respicio also says what he’d like to see happen is the department helping out local farmers by supplying them with the proper tools to succeed.
As a result of today’s discussions, Respicio says he is also working on piece of legislation to help the Department of Agriculture meet its mandates.
