2006) revealed that plants have semiochemicals
to attract beneficial insects to safeguard themselves and these plant derived substances influence the predator's behavior to locate the herbivores.
Ruther J, Steidle JLM (2000) Mites as matchmakers: semiochemicals
from host-associated mites attract both sexes of the parasitoid Lariophagus distinguendus.
Although ample literature is available on the aggregation of bedbugs however, not much attention has been paid to the chemical ecology of semiochemicals
from the excreta extract responsible for aggregation in tropical bedbug Cimex hemipterus.
derived from pyrrolizidine alkaloids in male ithomiine butterflies (Lepidoptera: Nymphalidae: Ithomiinae).
associated to spacing behaviour of the bird cherry-oat aphid Rhopalosiphum padi L.
Identification of semiochemicals
released by cotton Gossypium hirsutum, upon infestation by the cotton aphid, Aphis gossypii.
Indirect evidence indicates female semiochemicals
release male precopulatory behavior in the snow crab, Chionoecetes opilio (Brachyura: Majidae).
This releases semiochemicals
that repel the stem borer moths (the 'push' element).
34) At present, field studies are being conducted to determine the efficacy of a wide range of semiochemicals
, either repellents or attractants, on the activity of sand flies.
Deterrent activity by bitterwood derivatives would make it possible to eventually formulate a commercial product to be deployed during the critical period of susceptibility to begomoviruses and other viruses affecting tomato and other vegetables, to complement other tactics, as semiochemicals
by themselves very seldom provide robust pest control (Pickett et al.
In connection to this it should be noted the sense of the term semiochemicals
that the author specifies, he points out that it must embrace all chemicals which are involved as signs, in sign-mediated interactions in and between organisms.
of the engraver beetle, Ips perturbatus, in south-central and interior Alaska.
