The selected plants in order of preference on the basis of consumption were Sorghum >
Maize > Bermuda grass > Tomato > Cotton (NIAB-98) > Alfalfa > Rice >Castor oil >
Okra > Cattail > Cotton (CIM-446) > Horse purslane > Rape seed > Winter cherry>
Calotrope. The order of the preference on the basis of Coefficient of Utilization (CU) was
Sorghum > Bermuda grass > Maize > Cotton (NIAB-98) > Tomato > Winter cherry >
Castor oil > Alfalfa > Okra > Rice > Cotton (CIM-446) > Horse purslane > Calotrope >
Rape seed > Cattail. None of the plants was found completely resistant to H. armigera.
The correlation between food consumption and CU was significantly positive. Moisture
content showed positive while thickness of leaf lamina played negative role both for
consumption and CU. Moisture percentage alone contributed 50.8% and 40.5% role
towards resistance in term of consumption and CU, respectively. The cumulative effect
of all the morpho-physical plant factors was 80.1% for consumption and 57.8% for CU. |

The synthesis and spectroscopic investigations like 1H-, 13C-NMR of novel organotin (IV) esters are described. The FT IR study is successfully applied to verify the bonding mode of endo and exo status of tin (IV) of the dimeric nature of organotin (IV) compound 2. In vitro ED50, bactericidal, fungicidal, bioactivities are investigated, which indicate them significantly potential biocides. Based on spectroscopic analysis and literature evidences, the mono-and dimmer organotin (IV) esters are assigned tetrahedral and distorted octahedral cage type geometry. |

The leaves of sugarcane, rice and maize were utilized the maximum by M. separate with coefficient values of 71.06, 70.57 and 69.29 percent, respectively, while it was minimum in leaves of water grass (27.79%). Hair density did not show significant correlation with consumption values but it was significantly negative with coefficient of utilization. Thickness and moisture contents played a significant role with negative and positive responses with consumption and coefficient utilization, respectively. The actual contribution of Morpho-physical factors on cumulative basis was 52.1 and 68.9 percent for consumption and utilization, respectively. |

Optimum elements dosages i.e., 0.2%, 0.3%, 0.1%, 0.1%, 0.15% and 0.5% of various minerals i.e., N, P, K, Ca, Mg and Cu respectively in various combinations were studied on larval development and silk production of Bombyx mori L. The rearing of silkworm larvae was restricted to chopped tender and green mulberry leaves treated with different concentrations. The results revealed that mineral nutrients have not affected the yield component significantly but have also presented better food consumption, body weight, co-efficient of utilization and larval development as well. However, of all the test treatments T11 where the offered mulberry leaves were treated with 0.2% N + 0.3% K + 0.1% Ca + 0.1% P + 0.15% Mg + 0.5% Cu concentration gave the best results. |

Experiments were conducted under laboratory conditions to find out the most efficient method for harvesting the eggs of Chrysoperla carnea from the different substrates provided on the top of the adult rearing cage for egg laying purpose. Highest egg viability (82.89%) was found in the eggs removed by a razor from the granulated Maraco paper sheet used by AM-Tech rearing methodology whereas egg viability was lowest (64.89%) in the case of egg removed from black organdy with potassium hypochlorite solution. Modest egg viability (75.56%) was observed in the eggs laid on black organdy and removed by a razor. |

Sciarid fly, Lycoriella auripila is the most destructive insect pest of mushroom
causing serious threat to mushroom production and cultivation in Pakistan. Chemical
control is the most effective easier and quicker method to control this inset
pest which is commonly used by our farming community. So there was a dire need
to evaluate some commercial insecticides against this pest. The present study
was therefore, conducted to evaluate six commercial insecticides (deltamethrin,
spinosad, spintoram, trichlorphon, malathion and permethrin) against sciarid
fly for three consecutive years (2008 to 2010). During present study the insecticides
evaluation was done on the bases of three parameters viz. percent reduction
in adult emergence, mushroom damage rate by sciarid fly larvae and mushroom
yield per unit area. All insecticides caused significant reductions in adult
emergence and mushroom damage rates as compared to control. On overall bases
for three years, the data revealed that maximum reduction of adult emergence
(84.61, 86.32 and 83.42%) and minimum damage rate by sciarid flies (10.60, 9.53
and 13.73%) as well as maximum yield per plot (8.30, 8.02 and 8.12 kg/m2) was
observed in spinosad treated plots, followed by trichlorphon and deltamethrin
which were statistically at par. The results of present study showed that deltamethrin,
spinosad and trichlorphon may be very effective insecticides to control mushroom
sciarid fly in Pakistan. |
