Trichomes Save Insect From Beetle Predation

University of Guam Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator. The pest is called the cycad aulacaspis scale, and its invasion into numerous countries in recent years has caused immeasurable loss of biodiversity. Cycads belong to an ancient lineage of...

Conservation efforts need empirical studies The beautiful, endemic and endangered cycad, Cycas micronesica was once a dominant forest tree on the island of Guam, but recent plant mortality predicts extirpation from Guam habitats by 2019. This dire prediction by scientists at the Western Pacific Tropical Research Center (WPTRC), University of Guam is validated by the research of Thomas E. Marler and John H. Lawrence, which has concluded that Cycas micronesica is the only native host for the...

Collaborative research at the University of Guam has people asking: "What IS a species" and entomologists wondering about the relationship between an insect species and the host plant or plants it feeds on. Western Pacific Tropical Research Center (WPTRC) entomologist Ross Miller has been studying aphids for years and this work has brought him in contact with entomologists in Canada and the US mainland. Aphid systemetist Robert Foottit, DNA expert Eric Maw and aphid authority Keith Pike have...

University of Guam Marine Lab associate professor, Alexander Kerr, is senior author of a paper on the evolutionary origins of coral sex published in the Proceedings of the Royal Society B. The paper, "Correlated evolution of sex and reproductive mode in corals" finds that ancient corals consisted of mostly separate sexes and needed to pass through an evolutionarily period in which they brooded their young before they could become spawning hermaphrodites. "Most species of corals on tropical...

Researchers look for small control organism "The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore. Moore has teamed up with UOG ecologist Thomas Marler to study the relationship between the native cycad tree, known as "fadang" in the Chamorro language, and a minute alien insect pest called cycad aulacaspis...

Moth also triggers the plants into increased frequency of reproduction When a plant endemic to several islands in the Western Pacific Ocean taps the services of a helpful insect, a double-dose of benefits comes its way. The plant is a member of a unique group of plants known as cycads, which produce their seeds in cones rather than within fruits. The insect is a tiny moth currently known to exist only on the islands of Guam and Rota. The insect's primary role is to ensure seed production...

In May 2008 the island of Guam became a living laboratory for scientists as they attached acoustic equipment to coconut trees in order to listen for rhinoceros beetles. A grant from USDA IPM allowed Richard Mankin, a recognized world-class expert on acoustic detection of insects, to travel to Guam to collaborate with island scientists on the Guam Coconut Rhinoceros Beetle Eradication Project. The results of this research were recently published in the journal Florida Entomologist. The coconut...
