The common green lacewing Chrysoperla carnea is a key biological control agent employed in integrated pest management (IPM) programs for managing various insect pests. A field collected population of C. carnea was selected for emamectin benzoate resistance in the laboratory and fitness costs and realized heritability were investigated. After five generations of selection with emamectin benzoate, C. carnea developed a 318-fold resistance to the insecticide. The resistant population had a relative fitness of 1.49, with substantially higher emergence rate of healthy adults, fecundity and hatchability and shorter larval duration, pupal duration, and development time compared to the susceptible population. Mean population growth rates; such as the intrinsic rate of natural population increase and biotic potential were higher for the emamectin benzoate selected population compared to the susceptible population. The realized heritability (h 2) value of emamectin benzoate resistance was 0.34 in emamectin benzoate selected population of C. carnea. Chrysoperla species which show resistance to insecticides makes them compatible with those IPM systems where emamectin benzoate is employed. © 2013 Springer Science+Business Media New York. Source

The common green lacewing Chrysoperla carnea is a key biological control agent employed in integrated pest management (IPM) programs for managing various insect pests. Spinosad is used for the management of pests in ornamental plants, fruit trees, vegetable and field crops all over the world, including Pakistan. A field-collected population of C. carnea was selected with spinosad and fitness costs and realized heritability were investigated. After selection for five generations, C. carnea developed 12.65-and 73.37-fold resistance to spinosad compared to the field and UNSEL populations. The resistant population had a relative fitness of 1.47, with substantially higher emergence rate of healthy adults, fecundity and hatchability and shorter larval duration, pupal duration, and development time as compared to a susceptible laboratory population. Mean relative growth rate of larvae, intrinsic rate of natural population increase and biotic potential was higher for the spinosad-selected population compared to the susceptible laboratory population. Chrysoperla species are known to show resistance to insecticides which makes the predator compatible with most IPM systems. The realized heritability (h 2) value of spinosad resistance was 0.37 in spinosad-selected population of C. carnea. Copyright © Cambridge University Press 2014 . Source

Moth bean [Vigna aconitifolia (Jacq.) Marechal] susceptibility to yellow mosaic virus (YMV) purged the crop from the farming system. Therefore, genotype-by-environment interaction (GEI) and biplot studies were undertaken to develop YMV-resistant moth bean cultivars from the germplasm. The germplasm was acquired from the National Agricultural Research Centre (NARC), Islamabad and from the farm fields in two provinces, Punjab and Sindh, Pakistan. Two different groups of moth bean genotypes were screened for YMV versus seed yield (11 genotypes) and YMV versus fodder yield (10 genotypes) over three years (2006–2008) in three locations in Pakistan [D.I.Khan Agriculture Research Station (ARS), Serai Naurang ARS, and Karak ARS]. In all germplasm, four moth bean lines were identified as highly resistant to YMV with maximum grain (013393-C, 013388) and fodder (DMB-118-E, DMB-118-A) yields across all years and locations. Genotype, environment, GEI, and biplot analysis revealed that two moth bean lines (013393-C and DMB-118-E) showed the lowest YMV scoring (1) and maximum grain (33.40, 29.70, and 33.98 g plant–1) and fodder yields (15.30, 17.40, and 15.35 t ha–1) compared with susceptible checks, respectively. Keeping in view the genetic potential of YMV-resistance and the high grain and fodder yields of two moth bean lines (013393-C, DMB-118-E), the Provincial Seed Council (PSC) of Khyber Pakhtunkhwa, Pakistan approved the two lines with the highest grain and fodder yields as new moth bean cultivars, naming them Dera Moth and Green Moth, respectively. © TÜBİTAK.

Broad sense heritability and genetic advance were estimated among ten mustard {Brassicajuncea L.) genotypes for yield and yield contributing parameters in RCB design with three replications. Broad sense (BS) heritability estimates were higher (above 60%) for days to flowering, plant height, days to maturity, branches/plant and number of pods/plant. Moderate heritability values were observed for grain yield. The expected response to selection was higher (> 20%) for number of pods/plant and grain yield kg/ha and moderate values ranging from 10-20% for selection response was recorded for plant height. Days to flowering, days to maturity and number of branches/plant showed lower values (< 10%) for expected response to selection. The genotypes 022860, J-38 and 022862 have shown better results for most of the traits and could be used in focused future breeding programmes. Source
