Bio-potency of serine proteinase inhibitors from Acacia senegal seeds on digestive proteinases, larval growth and development of Helicoverpa armigera (Hübner)

Mechanisms by which pesticides affect insect immunity

“…However, we have not found any reports of pesticides affecting serine protease activity. Pesticides that are known to be protease inhibitors potentially might also interfere with melanization, such as the extract from seeds of the tree legume, Acacia senega (Babu and Subrahmanyam, 2010). Conversely, insecticide resistant strains of the mosquito, Culex pipiens, possess high serine protease activity, expressing up to three times the levels of activities found in non-resistant strains (Gong et al, 2005;Yang et al, 2008).…”

Isolation and in vitro identification of proteinase inhibitors from soybean seeds inhibiting helicoverpa gut proteases

“…This could be explained as the inhibitor being able to inhibit proteinases, other than those, which possess trypsin-like activity (Babu and Subrahmanyam 2010). This higher inhibitory activity toward general proteolysis would give more pronounced effects on larval growth and physiology (Srinivasan et al 2005).…”

Effect of Myracrodruon urundeuva leaf lectin on survival and digestive enzymes of Aedes aegypti larvae

“…Inhibition or stimulation of these digestive enzymes may result in a metabolic imbalance, growth impairment and mortality of insect larvae (Applebaum et al 1961;Borovsk and Meola 2004;Bhattacharyya et al 2007;Macedo et al 2007;Nanasahe et al 2008;Babu and Subrahmanyam 2010).…”
