Three California Ambrosia Beetles

Journal of Economic Entomology, 1929
The habits of the ambrosia beetles differ greatly from those of other members of the family Scolytidae. Three species are discussed in this article: Monarthrum scutellare Lec. and M. detigerum Lee. infesting oaks and Gnathotrichus sulcatus Lee. infesting Douglas fir.

Multigene phylogeny of filamentous ambrosia fungi associated with ambrosia and bark beetles

Mycological Research, 2009
Most 'ambrosia' fungi are members of a heterogeneous group of ophiostomatoids that includes the anamorph genera Ambrosiella, Raffaelea and Dryadomyces. The taxonomy of these fungi based on morphological features has been complicated by these features being poorly descriptive and having evolved convergently.

Control of Ambrosia Beetles, 1988

Insecticide and Acaricide Tests, 1990
Abstract Experimental plots were established at the Mauna Loa Macadamia Nut Corporation, Keaau, Hawaii, field 8. Trial 1 consisted of 4 blocks and trial 2 consisted of 6 blocks. Both trials were arranged in a complete randomized design with 1 tree/block.

Grape, Ambrosia Beetle Control Trial, 1985

Insecticide and Acaricide Tests, 1986
Abstract Thiodan 50W (120g form/100 liters (=1 lb/100 gal)) was applied in a vineyard with a history of attack by AB. The spray was applied on 19 Apr using a vineyard airblast sprayer. Four vine rows were sprayed, ca. 0.2ha (0.5A). Damage was evaluated on 8 May by visually examining vines for entry holes of AB. Twenty vines were examined

Mycetangia of the ambrosia beetle Monarthrum fasciatum

Journal of Invertebrate Pathology, 1967
Abstract Female beetles of Monarthrum fasciatum contain paired saclike mycetangia in the anterior, ventral prothorax. These large, specialized organs for storage and transport of the ambrosia fungus spores are apparently lined with sclerotized cuticular material and the posterior portion is heavily musculatured.

The Striped Ambrosia Beetle

1988
The striped ambrosia beetle, Trypodendron lineatum (Olivier) (Coleoptera: Scolytidae), is one of nature’s recyclers.10 Along with other ambrosia beetles, its ecological niche is to locate and infest dead and dying timber. It is a pioneer in the degradation process, exploiting this renewed habitat each spring, and leaving it within months to be further ...

Control of Ambrosia Beetle in Eucalyptus Stumps, 1984

Insecticide and Acaricide Tests, 1987
Abstract Three insecticides were tested to either prevent attack, or to control ambrosia beetles inside established galleries in newly cut Eucalyptus tree stumps. Tests were conducted at an experimental biomass plantation near Hilo, Hawaii, an area with a subtropical climate and average rainfall of 5000 mm/year. Tests were conducted in 2.

Taxonomy and Systematics of Bark and Ambrosia Beetles

2006
1. INTRODUCTION Bark beetles in a wide sense include the true bark beetles (many Scolytidae), which breed in and feed on the phloem (phloeophagous species), and the ambrosia beetles (many Scolytidae, and all Platypodidae), which bore into the wood and feed primarily on symbiotic ambrosia fungi living in the tunnels (xylomycetophagousspecies).

Acoustic communication of bark and ambrosia beetles

2019
Bark beetles and pinhole borers (Coleoptera: Curculionidae: Scolytinae and Platypodinae), also known as bark and ambrosia beetles, are two subfamilies of weevils that have evolved acoustic communication within plant tissue. These insects are able to transmit and detect sound in a medium that is neither air nor water, and are among the smallest animals ...
