The medicinal properties of Gloriosa superba, a perennial herb reproducing both by seed and tuber, are due to presence of colchicine in its seeds and tubers. The weak stemmed aerial part is annual which dries off after setting seed. Harvesting its tubers for medicament leads to destructive harvesting. Using seeds for drug purposes (with higher colchicines content as compared to tuber) has the advantage of annual harvest and also avoiding destructive harvesting. However, seed production under natural condition is quite low and uneconomical. It has been found that seed setting in the species is pollen limited. Results obtained have revealed that although the species is both self as well as cross compatible but seed setting is significantly influenced by pollination methods used. Controlled selfing between different flowers on the same plant have given significantly higher seed setting as compared to other methods tried. There was considerable increase in number of seeds produced per capsule (42.26) and dry seed weight per plant (1.13 g). It is suggested that for increasing seed set different flowers on the same plant should be selfed (Gnetonogamy) at stigma receptive stage.Keywords

Effect of different concentrations and dipping time periods of growth regulators IAA, IBA, NAA and GA3 on ischolar_maining, field survival and ischolar_mainstock biomass yield in important endangered alpine medicinal plant Picrorhiza kurroa revealed that pre-planting treatments of stolon cuttings by IBA 100ppm for 24 hrs resulted in maximum sprouting percentage (88.89 %), field survival (77.18 %) and dry ischolar_main-stock (economic part) biomass yield of 7.8 g/plant after two years. Treated cuttings can be directly field planted which can reduce the cost. An estimated yield of approximately 577 kg of dry ischolar_mainstock per hectare can be obtained after two years of field growth.- Evaluation of Different Collections of Mucuna pruriens for Morphological Parameters and L-dopa Yield

Mucuna pruriens, commonly known as Konch or Cowhedge is a traditionally used medicinal plant. Seeds of the species contain high percentage of active principle L-DOPA, which is used for curing Parkinson disease. There is a great variation in the seed colour of the species, and in the present study twenty eight black mottled with brown (collected locally) and creamish white (procured form NBPGR New Delhi) seeds were evaluated for morphological parameters as well as for L-DOPA content. Black seeded collections were found to contain high level of L-DOPA ranging 6.36 to 7.30. But, the seed yield and consequently L-DOPA yield was low ranging 38.40-65.86g and 2.35-4.69g per plant respectively Moreover, pods of these collections contain itching trichomes which puts workers in commercial cultivation Among black seeded collections regarding seed yield, L-DOPA content and L-DOPA yield collections Panba, Nagrota, Jwalaji Hilltop and Jwalaji excelled over all other collections. L-DOPA content in white seeded collections was low ranging 5.41-5.78 per cent. But, the seed yield and consequently L-DOPA yield was very high ranging 4.30-697.20g and 23.38-39.73g respectively. Also, pods of these collections are devoid of itching trichomes. Among white seeded collections regarding seed yield, L-DOPA content L-DOPA yield collection IC127363 and IC 127362 excelled over other collections. Exotic collection EC 144945 performed below par for all the parameters studied.Keywords

The second decade of the 21 century saw five insects, viz. cassava mealybug Phenacoccus manihoti Matile-Ferrero (Hemiptera: Coccomorpha: Pseudococcidae), desert locust Schistocerca gregaria Forskål (Orthoptera: Acrididae), fall armyworm (FAW; Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), rugose spiralling whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) and southern American pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) invading India having crossed international borders. While early warning system along with potential of testing Metarhizium acridum (Green Muscle™) through the Food and Agricultural Organisation exists for desert locust, an early importation of parasitoid Anagyrus lopezi De-Santis (Hymenoptera:Encyrtidae) against cassava mealybug is the need of the hour. Documentation of versatile native parasitoids (9), predators (3) and pathogens (6) on FAW implies potential of biological control through conservation and augmentative approaches in maize ecosystems. Fortuitous introduction of Encarsia guadeloupae Viggiani (Hymenoptera: Aphelinidae) in the late nineties along with an invasive spiralling whitefly Aleurodicus dispersus offering successful biocontrol of rugose spiralling whitefly indicated long-term sustenance of parasitoids in perennial plantations. Nevertheless, the internally feeding invasive southern American pinworm in open fields and protected tomato cultivation need biological products as a component of integrated pest management. A quick response in terms of delimitation and eradication is anticipated for transboundary insects and is only possible through establishment of an operational national digital reporting system with coordination and collaborations of not only all governmental and private stakeholders of plant protection in India, but also forging cooperation at regional and international levels for timely and effective management of transboundary insects.Keywords
