Cajuput (Melaleuca cajuputi)

Kayu putih or cajuput (Melaleuca cajuputi) is a tree in Myrtaceae as a medium to upper tree with thin skin and white, long slender green leaves and white flowers. This plant has important uses in agroforestry as a source of cajuput oil.

Cajuput is spread naturally in Indonesia and northern Australia. Indonesians traditionally use leaves to be distilled into essential oils of high economic value. This plant has a long biological cycle, grows fast and grows well in any soil with high salts or acids and is fire resistant.

Dlium Cajuput (Melaleuca cajuputi)

M. cajupati was divided into three subspecies: Melaleuca cajuputi cajuputi growing in Maluku and Timor islands, Melaleuca cajuputi cumingiana growing in Sumatra, Java and Kalimantan, while Melaleuca cajuputi platyphylla growing in Papua, Aru Islands and Tanimbar Islands.

M. c. cajuputi generally produces cajuput oil with a 1.8-cineol content and high yield. While the other two sub-species have lower levels of cineol. Kayu putih oil from the Maluku Islands has a concentration of 1.8 sineol around 50% - 60% and high yield.



Volatile kayu putih oil where on a hot day people will smell it remotely. Oil is extracted through evaporation mainly from leaves and twigs as an industrial product for balur oil or a mixture of other medicinal oils or a mixture of perfume and other household products.

Generally these plants are found as pure stands and grow in the lowlands. The difference in location of growing and geographical places influences differences in flowering, fertilization and growth times, but the influence of the environment for growth, oil and reproduction characteristics still needs further research.

Four new species and four newly recorded species of Omphale Haliday 1833 (Eulophidae) from China

NEWS - Researchers describe Omphale longigena , Omphale longitarsus , Omphale rectisulcus and Omphale xanthosoma as new species to science and four of their relatives ( O. brevibuccata Szelényi, O. connectens Graham, O. melina Yefremova & Kriskovich and O. obscura Förster) are reported from China for the first time; and a male O. melina is reported for the first time in the world. Omphale Haliday 1833 (Hymenoptera, Eulophidae, Entedoninae) includes 271 species worldwide, a cosmopolitan distribution and the second largest genus in Entedoninae. To date, 203 species from the Americas and Europe are divided into 18 groups. Prior to this study, only 11 species were known from China: O. longiventris (Ling, 1994), O. pulchra (Ling, 1994), O. gibsoni Hansson 2004, O. longiseta Hansson 1996, O. masneri Hansson 1996, O. mellea Hansson 1996, O. salicis (Haliday, 1833), O. stelteri (Boucek, 1971), O. straminea Hansson, 1996, O. sulciscuta (Thomson, 1878) and O. theana (Walker...

Purhepecha oak (Quercus purhepecha), new species of shrub oak endemic to the state of Michoacán, Mexico

NEWS - In Mexico, several Quercus shrubby species are taxonomically very problematic including 8 taxa with similar characteristics. Now researchers report the purhepecha oak ( Quercus purhepecha De Luna-Bonilla, S. Valencia & Coombes sp. nov.) as a new tomentose shrubby white oak species with a distribution only in the Cuitzeo basin in the Trans-Mexican Volcanic Belt (TMVB). Quercus Linnaeus (1753) subdivided into 2 subgenera and 8 sections of which section Quercus (white oaks) has the widest distribution in the Americas, Asia and Europe. This section is very diverse in Mexico and Central America with phylogenomic evidence indicating recent and accelerated speciation in these regions. The number of shrubby oak species in Mexico is still uncertain. De Luna-Bonilla of the Universidad Nacional Autónoma de México and colleagues found at least 3 taxa in the TMVB, specifically Quercus frutex Trelease (1924), Quercus microphylla Née (1801) and Quercus repanda Bonpland (1809). In 2016,...

Laniger bat tick (Ixodes lanigeri), new hard tick species (Ixodidae) from mouse-eared bats (Myotis) in Vietnam

NEWS - Researchers have identified Ixodes ticks from Vietnam based on morphological and molecular characteristics of females, nymphs and larvae as a new species, laniger bat tick ( Ixodes lanigeri ), which like other members of the Ixodes ariadnae complex appears to show a preference for vesper bats as a typical host. Historically, for more than a century and a half, only one species has been called the “long-legged bat tick”: Ixodes vespertilionis Koch. However, over the past decade, it has been molecularly recognized that long-legged ixodid ticks associated with bats may represent at least six species. Host associations and geographic separation may explain the evolutionary divergence of the new species from its closest living relative Murina hilgendorfi Peters in East Asia, Japan, as no Myotis or Murina spp. have overlapping distributions between Vietnam and the Japanese mainland. On the other hand, assuming that I. lanigeri may be present in other myotine bats and knowing that s...
