Several synthetic pesticides and allelochemicals used to treat Triatoma infestans adults by topic application showed some degree of cytosolic glutathione S-transferase (GST) induction. General inducers of detoxication systems such as phenobarbital and 3-methylcholantrene topically applied on T. infestans resulted in no GST induction. Meanwhile, general insecticide synergist such as piperonyl bu...

This study describes the isolation, identification of allelochemicals melon fly (Myiopardalis pardalina Bigot.), using GC-MS method. A food attractant has been identified and a method for synthesis its synthetic analogue developed. Also, route para pheromone, raspberry ketone, proposed.

How polyphagous herbivores cope with the diversity and unpredictability of plant defenses remains largely unknown at both the genetic and molecular levels. To examine whether generalist counterdefense enzymes are structurally more flexible and functionally more diverse, two counterdefensive allelochemical-metabolizing cytochrome P450 proteins, CYP6B1 from the specialist Papilio polyxenes, feedi...

A major problem in flower bulb cultivation is weed control. Synthetic herbicides are mainly used, although they cause a range of problems, and integrated weed control through application of naturally occurring allelochemicals would be highly desirable. Flower bulb production creates large amounts of leftover biomass. Utilizing this source for weed control may provide new applications of the bul...

Forests habituated by Rhododendron delavayi often lack understory vegetation, which could possibly be a consequence of allelopathy. It is phenomenon virtue certain plant species produce allelochemicals that affect the growth and behavior surrounding plants. To elucidate allelopathic potential present in different layers R. forest, extracts obtained from three forest were used for seed germinati...

The public health, tourism, fisheries, and ecosystem impacts from harmful algal blooms (HABs) have all increased over the past few decades. This has led to heightened scientific and regulatory attention, and the development of many new technologies and approaches for research and management. This, in turn, is leading to significant paradigm shifts with regard to, e.g., our interpretation of the...

Larvae of most butterfly species feed on a limited number of host species belonging to a single plant family. The choice of host plants is determined both at the egg-laying and larval-feeding stages (Schoonhoven et al., 1998). The choice of oviposition site by an adult female is crucial to the survival of their offspring, and thus the mother butterflies lay their eggs with great precision on th...
