Landscape – While the agents are doing their job, previously out-competed native species can gradually recover and recolonize areas without the need for extensive replanting. Safety – Biocontrol agents pose no threat to human health, crop production or beneficial organisms Spread – The control agents, be they insects or pathogens, locate and affect most – if not all – populations of a weed until they’re stopped by physical, environmental or chemical barriers, just as they would in their native range The weed is continually under attack from an army of natural enemies Sustainability – It’s permanent, and therefore completely sustainable. It also allows the amount of herbicides required for weed control to be reducedĬost – After the initial research costs, once the agents are established and having an impact on the weed the only further expenditure required would be that used for monitoring activities Further chemical characterization studies revealed that the main active metabolites contributing to extract activity were acetogenins and alkaloids.Īcetogenins Lace bug Corythucha gossypii Isoquinoline alkaloids Biocontrol Rollinia mucosa.Environmental – Biological control is natural and doesn’t rely on the use of man-made chemicals that can adversely impact an ecosystem. classical biocontrol agents were outlined for a model. In addition, with an insecticide assay on lace bug nymphs, a mortality percentage of 86.67% at 5 μg/mL after 72h was observed. An Alternative Approach for Evaluating the Efficacy of Potential. Probiotics are live microorganisms that offer health benefits to the host, when consumed in adequate amounts, by providing pathogen protective action and nutritional benefits. mucosa seeds was determined, as well as that of its Acetogenin (F1) and Alkaloid (F2) fractions these LC50 were 0.184, 0.082, and 0.0493 μg/mL, respectively. To overcome these problems, an environmentally friendly, cost-effective alternative approach is urgently needed. Through a toxicity assay involving Artemia salina, the median lethal concentration (LC50) of a raw ethanol extract of R. In the present study, a Rollinia mucosa (Jacq.) Baillon ethanol extract was evaluated as a biological control agent against the lace bug. Thus far, commercial insecticides, such as 0.1% Dimethoate and 0.1% Imidacloprid have shown effectiveness against this insect, but no botanical pesticides are available to control this bug. The lace bug, Corythucha gossypii (Fabricius) is a serious pest affecting over 24 wild and commercially important plant species of the families Annonaceae, Passiflorcae, Caricaceae, Euphorbiaceae, and Solanaceae.
