Abstract:The chemical composition of the essential oils of aerial parts and flowers of Chromolaena odorata (L.) R. M. King & H. Rob., collected from Western Ghats region, were obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). Fifty two and thirty four compounds were identified from aerial parts and flowers, representing 94.9 % and 95.2 % of the total oils, respectively. The essential oil from aerial parts was dominated by pregeijerene (14.2 %), epicubebol (9.8 %), cubebol (8.6 %), cis-sabinene hydrate (5.7 %), 10-epi-γ-eudesmol (3.8 %), germacrene-D-4-ol (3.6 %) and δ-cadinene (3.5 %), while germacrene D (24.8 %), geijerene (12.6 %), pregeijerene (12.5 %), cyperene (7.8 %), 10-epi-γ-eudesmol (4.7 %), α-muurolol (3.6 %) and khusimone (3.4 %) were identified as the major constituents of flowers oil of C. odorata.

“…The seeds are found stuck to animal skins and moved with grazing cattle, sheep goat, and perhaps wild animals. Elsewhere, it is reported to spread by wind, vehicles, animal fur, and clothing (Blackmore 1998;Zachariades et al 2009), and which is also true to the study area. In northern Telangana, the devil weed is present in Karimnagar District, though sparsely populated primarily along the rail tracks of Pothkapalli, Odela, Kolanur, Kothapalli, Peddapalli, Ramagundam and Peddampet villages.…”

The spread of devil weed is alarming in areas of podu cultivation, on the bunds of agricultural lands, wastelands, along roadsides, tracks, forest gaps, protected areas and plantations in the two said wildlife sanctuaries. It is found invading new territories easily along the river banks and steadily destroying the riparian elements. The manual removal of this weed (mechanical method) before flowering is the effective means to mitigate the spread of the species in comparison to the biological (Pareuchaetes pseudoinsulata, P. insulata, Actinote thalia-pyrrha) and chemical (Glyphosate, Triclopyrester) methods attempted. It is not trouble in its native habitat but is weedy in India for want of natural enemies to keep it under control. It is a mandate to prevent the loss of native biodiversity due to biological invasions. Conversely, there is an urgent need to devise action plans by managers of the respective wildlife sanctuaries to control and eradicate it. The local people are to be educated of its potential dangers to their farming on one hand and NTFP extraction from the local forests on the other. The Government of India has to develop a national level policy towards the control of invasive alien weeds in general and implement it at the earliest before we loose our indigenous biodiversity once for all.

“…Two biotypes of C. odorata have invaded different countries. The biotype in Asia has been substantially controlled in Papua New Guinea (Day and Bofeng, 2007) and East Timor (Zachariades et al, 2009;Day, personal communication) by the gall fly Cecidochares connexa. Natural enemy releases in South African against another biotype have resulted in establishment, but control has not yet occurred (Zachariades et al, 2009).…”

Keywords: Invasive species Ecosystem function Insect pests Invasive plants Ecological restoration Biological control Natural ecosystems a b s t r a c tOf the 70 cases of classical biological control for the protection of nature found in our review, there were fewer projects against insect targets (21) than against invasive plants (49), in part, because many insect biological control projects were carried out against agricultural pests, while nearly all projects against plants targeted invasive plants in natural ecosystems. Of 21 insect projects, 81% (17) provided benefits to protection of biodiversity, while 48% (10) protected products harvested from natural systems, and 5% (1) preserved ecosystem services, with many projects contributing to more than one goal. In contrast, of the 49 projects against invasive plants, 98% (48) provided benefits to protection of biodiversity, while 47% (23) protected products, and 25% (12) preserved ecosystem services, again with many projects contributing to several goals. We classified projects into complete control (pest generally no longer important), partial control (control in some areas but not others), and ''in progress," for projects in development for which outcomes do not yet exist. For insects, of the 21 projects discussed, 62% (13) achieved complete control of the target pest, 19% (4) provided partial control, and 43% (9) are still in progress. By comparison, of the 49 invasive plant projects considered, 27% (13) achieved complete control, while 33% (16) provided partial control, and 49% (24) are still in progress. For both categories of pests, some projects' success ratings were scored twice when results varied by region. We found approximately twice as many projects directed against invasive plants than insects and that protection of biodiversity was the most frequent benefit of both insect and plant projects. Ecosystem service protection was provided in the fewest cases by either insect or plant biological control agents, but was more likely to be provided by projects directed against invasive plants, likely because of the strong effects plants exert on landscapes. Rates of complete success appeared to be higher for insect than plant targets (62% vs 27%), perhaps because most often herbivores gradually weaken, rather than outright kill, their hosts, which is not the case for natural enemies directed against pest insects. For both insect and plant biological control, nearly half of all projects reviewed were listed as currently in progress, suggesting that the use of biological control for the protection of wildlands is currently very active.
