Control
of insects
 |
The
cultivation of tobacco is highly susceptible to the noxious agents
mainly to insects (plagues) and illnesses although they also provoke
severe damages to the overgrowths. |
That is why
a system of fight against these agents to control them is necessary. We
should highlight that the use of chemical substances, although in occasions
it is justified and it is necessary, should be reduced at a minimum, because
this substances affect the characteristics of the smoke and on the other
hand, they can contribute to increment the aggressiveness produced by
the smoke of tobacco affecting the human being's health.
It is good
to highlight that the plant of tobacco produces a group of alkaloids,
particularly the nicotine, that have insecticide effect and even under
this condition in our province exist around seven species of these insects
standing out among them:
Heliothis
Virenscens F, known as Cogollero of Tobacco, this plague feeds
from the buds and very young leaves causing significant perforations in
the foliage of the plant.
Spodoptera
Sunia, is known as Mantequilla (Butter), it affects the basal
and inferior leaves.
Protoparse
sp, This lepidopteron is the one that reaches the biggest size
and in spite of that it doesn't cause severe damages.
Subterraneous
Fertia, common name Cachazudo, it feeds from the leaves of the
plant, it has night habits and stays in the soil, it is a lepidopteron
and therefore its buccal apparatus is chewer. This plague in general doesn't
cause severe damages.
Myzus
Persicae, known as Pulgones and our peasants denominate it Piojillo
because of its tiny size contrary to the previous ones that present chewer
buccal apparatus and they are characterized for being of the type that
bite and suck, although this plague has always been present in the plantations
of tobacco it is not until the decade of the 90s that becomes a harmful
insect not only because it sucks the sap to the plant, but also because
it facilitates the appearance of an opportunist illness that is denominated
Fumagina.

Myzus
Persicae |
Heteroderes
Laurenti, is a chewer plague that stays in the soil and produces significant
damages to the radical system of the plant, the larvas constitute the
harmful phase.
Lasioderma
Serricorne, well-known in Cuba like Perforator of tobacco and Gorgojo
of tobacco, this insect feeds from the stored leaves and it causes big
damages in warehouses and even in rolled cigars when an integral system
of fight is not carried out efficiently.
Integrated
system for the control of insects (plagues)
An efficient
integrated system of control of insects in tobacco is the angular stone
to be able to produce the aromatic leaf with a high degree of environmental,
economic and social sustainability that in turn implies to minimize the
aggression to the environment and that guarantee the smoker a product
of high quality with appropriate characteristic and a minimum of agro-toxics.
In the integrated fight the important thing is not to apply one or another
measure, but that all those that be applied interact in an appropriate
way, that is to say it is necessary to stimulate the synergetic effects
on one hand and when necessary to stimulate the antagonistic ones. Next
we relate the main elements that are kept in mind in Pinar del Rio to
control in an integrated way the main plagues.
- The use
of resistant varieties.
- Use of
trap plants.
- Rotation
of cultivations.
- General
measures to increase biodiversity.
- Application
of traps.
- Sowing
of vegetable species repellent to insects.
- Application
of chemical products of natural origin.
- Use of
biological control
- Use of
the masculine sterility (it is not still applied)
- Application
of efficient system of works of cultural attentions to tobacco.
- Application
of chemical products not very aggressive to the environment.
