“…It was found that an augmentative release of the Z. bicolorata adult proved to be very effective and significantly reduced the soil seed bank to the magnitude of 60.21%, irrespective of the flushes at the end of the season. A similar reduction in the P. hysterophorus density and plant height in the augmented sites, as compared to the non‐augmented sites, over a period of 3 years also was observed by Sushilkumar (). In the present investigation, the significant reduction in the soil seed bank that was recordedwas assigned to two factors: (i) the biocontrol agent led to decreased flower production; and (ii) even after completely defoliating the plants, a proportion of the beetle population in the experimental area did not migrate and continued to oviposit on the flower heads and the larvae that emerged fed on the flowers, thus preventing seed production.…”

“…The augmentation of Z. bicolorata not only resulted in the significant reduction of the P. hysterophorus biomass but also replaced it with other competitive weeds, as their collective biomass increased significantly. The observed level of reduction, however, was higher than that reported by Kumari et al () and Sushilkumar (). This was related to the appropriate timing of the beetle release that was optimized with the weed flush levels.…”

Systematic information on the quantitative impact of Z ygogramma bicolorata on the biology of P arthenium hysterophorus is crucial as the seeds of this weed continue to germinate from the accumulated soil seed bank throughout the year in the form of different germinating flushes, while the activity of the beetle ceases during winter as it enters diapause. Therefore, plant–herbivore interactions need to be explored to develop predictions of the overall impact of the introduced beetle on the weed. The findings revealed that defoliation by Z . bicolorata had a significant impact on the plant height, density and flower production in flushes F 3, F 4 and F 5, but not in F 1 and F 2 that exhibited longer periodicity, profuse branching, a longer flowering period and maximum flower production and contributed mostly to the existing seed soil bank. Therefore, total depletion of the existing soil seed bank was not possible. Consequently, the effect of augmentative field releases of laboratory‐reared beetles was explored on F 1 and F 2 in February for three consecutive years (2011–2013). Before initiating the trial, random soil samples were taken from the plots that were assigned to the paired treatments (i.e. with the beetle and without the beetle [insecticide‐treated]) and it was found that the seed bank in those samples did not differ. The single release of Z . bicolorata adults at five per plant at the six‐leaf stage significantly reduced the soil seed bank, compared to without the biocontrol agent, irrespective of the flushes at the end of the season.

“…parthenium hysterophorae (rust fungi) were introduced in India as the biocontrol agents (Sankaran, 2017). Of these, augmentative releases of Zygogramma bicolorata has resulted in a reduction in the pathenium density and plant height with decrease in parthenium stand over a period of 3 years, in the augmented sites (Sushilkumar and Ray, 2011). The biocontrol efficacy was low, of several pathogens recorded on parthenium in India, except for Sclerotium rolfsii, (Sushilkumar and Saraswat, 2001).…”

Agriculture is the major source of livelihood for nearly half of the Indian population. However, the productivity of crops is much lower than many countries and needs enhancement to produce ∼400 million tons of food grains for meeting food demands of a population of 1.7 billion by 2050. Diverse climatic conditions in India favor the most adopted weeds to prevail and cause severe crop yield losses. Weeds also degrade quality of the produce, raise cost of production; harbor and serve as alternate hosts to several insect pests and diseases. Parthenium hysterophorus L.; Phalaris minor Retz.; Leptochloa chinensis (L.) Nees.; Echinochloa spp.; weedy rice; Lantana camara L.; Chromolaena odorata (L.) R.M. King & H. Rob.; Mikania micrantha Kunth., are a few of many major weeds of concern currently in India. Weed management in India is critical to improve crops productivity by minimizing weeds caused crop yield losses and to alleviate other adverse effects of weeds in different ecosystems. In spite of the progress made in evolving weed management technologies for different crops and other ecosystems, weeds continue to be a concern in varying ecosystems. The real challenges of Indian weed research are: managing weeds in small farms; non availability of labor and mechanical tools; inadequate information on weed biology and shifts in weed flora; herbicide resistant weeds; lack of understanding on the impact of climate change on weeds and weed control; popularizing integrated weed management with herbicides use by ensuring safe use to avoid adverse effect on human health, environment and avoid weeds developing herbicide resistance and prevention of entry and management of alien invasive weeds. The greatest opportunity of Indian weed science is the potentiality of appropriate weed management technologies to substantially improve the crops productivity. Thus, weed scientists have a greater role to play in the development, popularization and adoption of location specific effective, economical and eco-friendly weed management technologies for different ecosystems of India.

“…Several insects and pathogens have been tried in different parts of the world in different time. Some of the biocontrol agents utilized so far includes; Epiblema strenuana (stem-galling moth) [84], Bucculatrix parthenica (leaf-mining moth), Platphalonidia mystica (stem-boring moth), Zygogramma bicolorata (leaf feeding beetles) [85][86][87], Listronotus setosipennis (stem-boring weevil), Conotrachelus albocinereus (stem-galling weevil), Semicronyx lutulentus (seed-feeding weevil), Carmenta ithacae (root-boring moth), Puccinia abrupt (winter rust fungus) [88], and Puccinia melampodii (summer rust fungus) [87].…”

Parthenium hysterophorus is the seventh noxious alien species distributed in different part of the world. This dangerous plant is known for its negative impact on biodiversity, agriculture and human being. Parthenium plant is capable of causing allergic respiratory problems, contact dermatitis, diarrhea, skin allergy, skin rashes excessive water loss, mutagenicity, both in human and livestock. There are different attempts to control parthenium weed in which most of the methods are not successful due to rapid re-infestation of the plant. Even though parthenium plant is known for its toxicity, it is traditionally used for the treatment of fevers, headaches, wounds, diabetes, diarrhea, anemia, heart troubles and malaria to list some in different part of the world. The aim of this review article is mainly to explore the chemical components and antimicrobial property of parthenium hysterophorus. In this review the effect of parthenium on environment, human being and agriculture and major controlling practices have also been summarized.
