Small Southern Pine Engraver Ips avulsus

Date

February 6, 2020 02:56 PM EST

Description

Length: 2.5 mm. One of three species of scolytines that I found infesting a longleaf pine branch that had broken off of the tree about 1-2 weeks prior. This species was found in phloem galleries in branches that were 2 to 2.5 cm in diameter.

Description

Length 2.2 mm. Unfortunately broke off two legs after pinning.

Found in Ips grandicollis galleries, which were in a longleaf pine branch that had broken down from the tree about 1-2 weeks prior.

This beetle was quite quick and nimble, compared to the ponderous Ips adults. This species and L. referendarius are both known to dwell in bark beetle galleries in eastern pines - they do feed on phloem and fungi, but also will predate on the Ips larvae and pupae. So, they are one of the lesser-known natural controls for pine bark beetles.

Description

1.7 mm long, ID'd with Tom Atkinson's keys. Collected from phloem galleries in small-diameter (2 cm) portions of a longleaf pine branch that broke and fell from the tree about 2 weeks ago. Needles still not fully wilted, but I've found at least 4 species in this branch so far - 3 scolytines, and one zopherid (the others will be documented as I get to them).

Date

Description

Infesting a dead longleaf pine tree. I collected some soldiers for ID. Two pictures given against a calibration ruler, with tick marks 0.5 mm apart.

Identified using Scheffrahn and Su's key to Florida species: http://www.tsusinvasives.org/dotAsset/a997a125-9d3f-4edf-8df8-a98d69b3f843.pdf. I think that these often get mis-identified as R. flavipes, simply because that's a better-known species. Since I've started collecting samples from both dead and live tree infestations in North Florida, all of them have keyed out to R. virginicus.

Key characters to distinguish from other Reticulitermes spp:
Length of head including mandibles: 2.65 mm
Width of pronotum: 0.79 mm.
Inward angle of left mandible tip: close to 90 degrees.
(Measured using IC Measure 2.0.0.161 software.)

Description

1.8 mm long. Recovered from galleries (tunnels) in shoots of a dead loblolly pine sapling. The primary cause of death appeared to be a fusiform rust infection lower on the stem - these guys were likely secondary, taking advantage of the dying plant.

Found on a small loblolly pine stem that I had cut down for a bark beetle rearing project. Microscope picture shows fine punctation on the head and the relatively blunt anterior pronotal angles, which distinguish this species from T. acuta.

Female beetle, 2.2 mm long. Collected from redbay trees with symptoms of laurel wilt disease. Small local flare-up of laurel wilt, in trees that had apparently sprouted from the stumps of trees that were originally killed about 7-8 years ago (based on tree rings). Also shown: cross-section of wood with staining showing the outline of the beetle's galleries (tunnels), stem with "sawdust noodles" coming from beetle entrance hole, and wilted crown of tree. Also, one cutaway shot of a beetle within her gallery, within stained wood.

Description

Termites infesting the decayed base of a still-living sand live oak. I was lucky enough to get both alates (reproductive caste) and soldiers, helpful for ID. I've been finding that R. virginicus is more common in trees than R. flavipes in North Florida.

Identified using Scheffrahn and Su's key to Florida species: http://www.tsusinvasives.org/dotAsset/a997a125-9d3f-4edf-8df8-a98d69b3f843.pdf

Key characters to distinguish from other Reticulitermes spp:
Alate-
Length (including wings): 8 mm
Ocellus less than its width away from compound eye.
Forewings with clear/hyaline membrane and costal veins (except near base).
Soldier-
Length of head including mandibles: 2.4 mm
Width of pronotum: 0.75 mm.
Angle of left mandible tip: slightly less than 90 degrees

About 4.2 mm long, excluding antennae. Someone had cut down some sabal palmettos in a natural area, so I pulled open some of the furled palm fronds at the top to look for these guys. Distinguished from H. marginipennis by the elytra that cover the last abdominal tergite, and from H. microphthalmus by the larger eyes (and the host plant).

Description

Beneath the bark of a longleaf pine that had been struck by lightning. ID'd using the key to soldiers in Scheffrahn and Su (1994): http://www.tsusinvasives.org/dotAsset/a997a125-9d3f-4edf-8df8-a98d69b3f843.pdf.

Distinguished from R. flavipes by the shorter length of head (2.4 mm including mandibles), and from R. hageni by the sharper angle formed by the tip of the left mandible (about 90 deg). But I'm not very well-versed in termite ID, so I welcome any confirmation or correction.
