The effect of food source (mung bean Vigna radiata vs. black-eyed pea Vigna unguiculata) on relative inhibition of acetylcholinerase due to malaoxon in bean beetle Callosobruchus maculatus Background and Hypotheses: Recent studies‚ most notably Gbaye et al. (2011‚ 2012)‚ have investigated the sensitivity of bean beetles in the genus Callosobruchus to organophosphate insecticides (OPs). Economically this is important work given that these beetles are pests that threaten agricultural yields

including grains such as lentils‚ chickpeas‚ and cowpeas‚ black-eyed beans‚ or Vigna unguiculata. These grains serve as primary sources of protein those who live in tropical and subtropical Asia and Africa‚ and when C. maculatus lay eggs into grains‚ the grains can no longer be eaten or replanted (Owolabi et al.‚ 2014)‚ leading to quantitative and qualitative losses once the larvae insert eggs and droppings in the Vigna unguiculata (Torres et al.‚ 2016 ) These larvae usually lay eggs on the surface

Chapter 1 INTRODUCTION I. Background of the Study The red rice beans have the best medicinal qualities of all beans. 16th century herbalist/physician Li Shizhen wrote this about the red rice bean: “induces the production of good fluid‚ facilitate urination‚ reduces swelling‚ stops vomitting; To be used to treat diarrhea‚ alcohol intoxication; Helps to get rid of the swellings of winter fires‚ stops pus and dilutes the blood‚ induces milk flow…”. Unlike all the beans mentioned above‚ red

The data from this experiment seemed to show Callosobruchus maculatus oviposition occurred less on black-eyed beans when the legumes were covered with sunflower oil. In all trials‚ the least number of eggs were laid on the beans coated with 15 mL/kg sunflower oil‚ an intermediate number of eggs were laid on the ones coated with 5 mL/kg‚ and the most were laid on the cowpea without sunflower oil (Figure 4‚ Figure 5). No eggs were laid in quadrant C‚ which reinforces the idea that bean beetles will

Title: Amount of Oxygen‚ Mung Beans (Vigna Radiata) Consume during Cellular Respiration Introduction: Cellular respiration is a catabolic reaction that refers to the process of converting chemical energy of organic molecules into a simplify form so it can be used immediately by organism. Glucose may be oxidized completely if sufficient oxygen is available‚ by the following equation: C6H12O6 + 36 ADP + 36Pi + 6O2(g) 6 H2O + 6 CO2(g) + 38 ATP + heat All organisms‚ including plants and animals

Effect of Calcium on Plant Growth Problem Statement What affect do various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium added to Vigna unguiculata (black eyed pea plants) once a week have on the overall growth (height‚ number of leaves‚ number of pods) over a 30 day period of time? Research Hypothesis If various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium are added to Vigna unguiculata (black eyed pea plants) once a week‚ then those plants receiving 300 mg of Calcium will have a greater overall growth
