Pearson-1989 #36 short, live culm with a dead top, and 27 dead shoots. At least 20 of the 27 death shoots had been parasitized. So 43 shoots had appeared last summer in this clump, 15 of them were healthy (35%), and at least 47% had been parasitized. One new shoot was just emerging. October 30- Cerro Otto. Measured clump A1 out in the open field. Only 1 yearling culm and NO dead shoots. The yearling was smallish but not parasitized. October 31- Cerro Otto. Measured clump A2 in the forest. It had produced 14 live yearling culms and 16 dead shoots. All 16 of the dead shoots had clearly been parasitized. 10 of the 14 yearling culms had dead tops, and 9 of these had been clearly parasitized. So this clump had produced 30 new culms of which only 4 were healthy and 25 had been killed or truncated by parasites. November 1- Llao Llao Peninsula. Counted leaves and yearling culms. There were 11 living yearlings (1 of them with dead top), 7 dead shoots, 4 of which were definitely parasitized. So, total production for the year of 18 new culms; 10 of them healthy, 7 died in infancy, at least 4 of them killed by parasites. November 11 - Llao Llao. Measured leaves and interleaf distances on marked leaves on plant L6. Then checked the bamboos on the side trail. The one that we decapitated 2 years ago is now essentially dead; still a little green color in the bottom few internodes but no leaves or branches. Two other adjacent culms of the same size that had the tops killed by parasites are almost dead; only two leaves on each of them. Two nodes on a healthy culm that had all the branches removed (from these two nodes) had produced no new branches. On the way out lying in the trail was a big fresh culm about 1 inch diameter that someone had cut. Two internodes near the base had neat 3.5 mm exit holes (one in each internode) and tunnels inside of the internodes full of frass. They were in adjacent internodes but did not pass through the separating node. The culm itself looked green and healthy. November 16 - Castano Overo. With Anita and Alberto Sosa to our campsite on the Rio Castano Overo. Lupines just beginning to come out, some Berberis darwini out, B. linearifolia has berries. Saw one flowering bamboo along the Rio Manso. Measured bamboo at the clump by the road. 10 dead shoots, 9 of them parasitized. Then set out traps alternating Shermans and Museum Specials. About 24 in the mallin in grassy/juncus/bushy places; squooshy underfoot (but the road in was almost dry). Also put about 20 more along logs in bamboo and forest along the road. Weather sunny and warm, no wind, and heard no glaciers. November 17 - Castano Overo. Checked the clump in the woods. It had about 8 new live yearling culms and 2 dead shoots, both of which were parasitized. Collected branch samples from a known-age culm for analysis of leaf
