The dodder builds a canopy on the
host plant and casts thousands of tendrils to form a dense spectacle before it strangles it.GERMINATIONAccording to scientists, the weed spreads mainly through contaminated crop seed, although vegetative spread is also possible.
Chinavia hilaris fed and successfully developed to adults on mimosa fruit (i.e., pods), confirming mimosa as a reproductive
host plant for this stink bug.
It is not currently thought to cause any problems for the
host plant beyond the unsightliness of the egg masses, which resemble a white wrapping around the branches, the horticultural experts said.
In this context, this experiment investigated under field and laboratory conditions the influence of the
host plant of P.
Aphis gossypii with 17
host plant species was the most polyphagous species followed by Myzus persicae and Aphis fabae that infested 15 and 12
host plant species respectively.
Most of the damage is caused during the larval stages, when the larvae feed on and tunnel through the woody portion of the
host plant trunk.
Dietary requirement and fitness of phytophagous insect pest depend upon the nutrient chemistry of
host plant. The present research was carried out to investigate the association of host-plant-preference and mortality of Phenacoccus solenopsis first instar influenced by chemical characteristics of plant species.
The biometric study concerned only the larvae collected on cork oak, the main
host plant of L.
The injuries presented by these plants as partial or total plant dry is similar with those observed for some species of Diaspididae, differing from damage mentioned by Howell and Kosztarab (1972) to some members of Lecanodiaspididae that typically cause a depression in the
host plant's tissues and often distortion of the shoots.
MULTAN -- The Cotton Research Station (CRS) discovered lady finger (Okra- vegetable) as second
host plant of Pink Bollworm, which has been damaging cotton crop seriously for last three years.
More recently, studies have shown that several macromolecules move from the
host plant to dodder, including proteins (Haupt et al., 2001) and phloem-mobile mRNA transcripts (Roney et al., 2007).
In order for a grapevine to be infected by PD, it must be a susceptible variety and there must be an insect vector present to transmit the bacteria from a
host plant to the susceptible vine when the insect feeds on the vine's tissue.
