Antifeeding Active Substances for Insects in Clerodendron tricotomum Thunb

Insect Antifeeding Substances in Plant Leaves

Insect antifeeding substances contained in plant leaves were widely surveyed by monitoring with 'leaf-disc test'. Larvae of tobacco cutworm, Spodoptera litura F., were mainly the test insects and leaves of sweet potato, Ipomoea batatas Lamark var. edulis Makino, the insect baits. Leaves of Cocculus trilobus DC, Parabenzoin trilobum Nakai (= Lindera triloba Blume), Orixa japonica Thunberg, Clero...

Cloning Serratia entomophila antifeeding genes--a putative defective prophage active against the grass grub Costelytra zealandica.

Serratia entomophila and Serratia proteamaculans (Enterobacteriaceae) cause amber disease in the grass grub Costelytra zealandica (Coleoptera: Scarabaeidae), an important pasture pest in New Zealand. Larval disease symptoms include cessation of feeding, clearance of the gut, amber coloration, and eventual death. A 155-kb plasmid, pADAP, carries the genes sepA, sepB, and sepC, which are essentia...

Increasing the Efficacy of Electrolyte Active Substances

An adjuvant composition containing a) one or more alkyl glucamides of the formula (I), wherein R1 represents a linear or branched alkyl group having 5 to 9 carbon atoms, R2 represents an alkyl group having 1 to 3 carbon atoms; b) at least one water-soluble ammonium salt, preferably selected from the group consisting of ammonium sulfate, ammonium nitrate, ammonium nitrate urea, ammonium phosphat...
