The bacterial isolate Paracoccus sp. strain FLN-7 hydrolyzes amide pesticides such as diflubenzuron, propanil, chlorpropham, and dimethoate through amide bond cleavage. A gene, ampA, encoding a novel arylamidase that catalyzes the amide bond cleavage in the amide pesticides was cloned from the strain. ampA contains a 1,395-bp open reading frame that encodes a 465-amino-acid protein. AmpA was ex...

the side effects of three pesticides, hexaflumuron, pymetrozin and spirodiclofen and four plant extractions including, calotropis procera (willd.) r. br. (asclepiadaceae), teucrium polium (labiatae), fumaria parviflora lam. (fumariaceae) and thymus vulgaris l. (labiatae) were evaluated on survival rate and reproductive parameters of chrysoperla carnea (stephens) at 26±1oc, 60±5% rh and 16:8 (l:...

common pistachio psylla, agonoscena pistaciae burckardt and lauterer (hemiptera: aphalaridae) is one of the economical pest among the pistachio orchards. the adonis' ladybird, hippodamia variegata (goeze) (col: coccinellidae) is one of the most prominent coccinellid predator in pistachio orchards. it is omnivorous and feed on aphids and psylla. functional response studies using a suitable ...

Coptotermes travians (Haviland) is one of the most important subterranean termite pest species attacking urban buildings and structures in Malaysia. Two colonies of C. travians infesting residential premises (Colony A & B), and another one in a natural habitat (Colony C) were characterized. Foraging territories ranged between 125 384 m2, with maximum foraging distances of 17 32 m per colony. At...
