[3] It is native to the Sahel regions south of the Sahara (from Mauritania and Senegal to Sudan ), tropical and subtropical eastern and southern Africa ...
Rose rosette disease – This disease is caused by a relatively recently described virus, Rose rosette emaravirus, [10] that is transmitted by an eriophyid, rose leaf curl mite (Phyllocoptes fructiphilus), which inhabits the shoot tips and leaf petal bases of roses, as well as by grafting but not by seed or many other common vectors.
The genus Adenium has been held to contain as many as twelve species. These are considered by other authors to be subspecies or varieties. A late-20th-century classification by Plazier recognizes five species. [5] Species [3] Adenium arabicum Balf.f. = Adenium obesum; Adenium boehmianum Schinz - (Namibia, Angola) Adenium multiflorum Klotzsch.
The complete picture of long-term ecological effects from invasive pests is difficult to measure; and it is too early to determine the effects of the many new invasive pest introductions. Much of the research has focused of the biology of the pests—i.e. life cycle and host preferences—towards understanding how to contain their spread. [10]
Apocynaceae (/ ə ˌ p ɑː s ə ˈ n eɪ s i ˌ aɪ,-s iː ˌ iː /, from Apocynum, Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, [1] because some taxa were used as dog poison.
The Food and Agriculture Organization estimates that pests and diseases are responsible for about 25% of crop loss. To solve this, new methods are needed to detect diseases and pests early, such as novel sensors that detect plant odours and spectroscopy and biophotonics that are able to diagnose plant health and metabolism .
