PHOTOTOXINS AS INSECTICIDES AND NATURAL PLANT DEFENCES

Memoirs of the Entomological Society of Canada, 1991
AbstractThe thiophenes alpha-terthienyl and methyl-alpha-terthienyl are found in many species of the family Asteraceae and are highly phototoxic to mosquito larvae. These compounds and a synthetic analogue, cyano-alpha-terthienyl, controlled Aedes intrudens Dyar (Diptera: Culicidae) larvae at application rates between 10 and 40 g per hectare in field ...

Marine Natural Products as Prototype Insecticidal Agents

Journal of Agricultural and Food Chemistry, 1997
In an attempt to characterize additional structural classes that could serve as prototypes for insecticides, 26 structurally diverse marine compounds were examined for insecticidal activity in a di...

Progress in developing insecticides from natural compounds

1993
Abstract Approximately one third of world food production is lost through damage caused by pests. The most efficient method of controlling insect pests relies on the use of insecticides (compounds which kill insects) many of which act on the insect nervous system.

Chemists synthesize natural insecticide in 16 steps

C&EN Global Enterprise, 2019
Although chemists have known about the molecule perseanol since the 1990s, no one has completed a total synthesis of the complex, polycyclic insecticide, until now. California Institute of Technology chemistry professor Sarah E. Reisman and graduate students Arthur Han and Yujia Tao constructed perseanol in just 16 steps, starting from a commercially ...
