Previous issue date: 2009-10-17 / The present reseaech paper was made in the District,Province and Region
Lambayeque located in northern Perú during the agricultura seasons: 2004-2005, 2005-

This research work is run in the District, Province and Region Lambayeque, Peru during
the crop season 2004-2005, 2005-2006 and 2006 - 2007 with the objective of evaluating
the behavior of the entomofauna and yield potential native cotton (Gossypium
barbadense L Ssp. Peruvianum).) cotton called "country". The crop was installed in June
2004 beginning with a nursery, in an area corresponding to Ferreñafe Sican Museum
and its final installation in the field of Sipan Museum in Lambayeque, at an altitude of 29
meters, average temperature 22.5 º C, humidity on 75% and an average rainfall of 24
mm. 1.333 plants were installed. Also served to assess the ecotypes of color, material
valued for its natural color, with a genetic resource of great value to work rescuing this
poor germplasm, which is in danger of extisiòn due to the introduction of commercial
hybrid , that would put in risk so precious ancestral legacy. We found significant genetic
variation in all attributes evaluated. Ferreñafe province had the highest genetic variability
in fiber color, the colored ecotypes present five out of nine. The most critical phases of
pest attack were sprouting, fruiting and capsule opening. There was a low infestation of
worm borer leaf Bucculatrix thurberiella, "Arrebiatadas" Dysdercus peruvianus "Peruvian
beaked" Anthonomus vestitus and "wart mite" Acaliptus gossypii, mainly due to
unsuitable conditions for their development. The native cotton crop will be greatly
affected by the attack of pests if not done an adequate integrated pest management.
The more promising ecotypes were: Orange-face, Fine red, white and pink White simple,
2903, 1880, 1642 and 1.24 kilos per plant, respectively. For weight of weed, highlights
the ecotypes: Fine Colorado Claro Fifo 3.95 to 2.96 g, respectively, was found in the first
harvest of the arboretum A , a greater number of fruit branches with 43,797 branches,
with respect to the soca harvest, which formed only 10,643 fruit branches. In the
arboretum "B", the results were the same trend. Sample sizes were adequate and
representative of the population. The data had a normal or approximately normal
distribution. / El presente trabajo de investigación se ejecutó en el Distrito, Provincia y
Región Lambayeque-Perú, durante las campañas agrícola 2004-2005, 2005-2006 y
2006- 2007 con el objetivo de evaluar, el comportamiento de la entomofauna y el
potencial de rendimiento de algodones nativos (Gossypium barbadense L. Ssp.
Peruvianum) , denominado algodón del país . El cultivo se instaló en Junio 2004
iniciándose con un vivero, en un área correspondiente al Museo Sicán de Ferreñafe y su
instalación definitiva en el ámbito del Museo de Sipán, en Lambayeque. Se instalaron
1,333 plantones. Además sirvió para evaluar los ecotipos de color, material valioso por
su coloración natural, siendo un recurso genético de gran valor para trabajos de rescate
de este escaso germoplasma, que se encuentra en peligro de extinción debido a la
introducción de híbridos comerciales y cultivares transgénicos, que pondrían en riesgo
tan preciado legado ancestral. Se encontró variabilidad genética significativa en todos
los atributos evaluados. La provincia de Ferreñafe presentó la mayor variabilidad
genética en color de fibra, al presentar cinco ecotipos coloreados de un total de nueve.
Las fases más críticas para el ataque de plagas fueron en brotamiento, fructificación y
apertura de cápsulas. El cultivo de algodón nativo se verá muy afectado por el ataque
de plagas si no se realiza un adecuado manejo integrado de plagas. Los ecotipos más
rendidores fueron: Anaranjado-Ante, fino colorado, blanco rosáceo y blanco simple, con
2.903, 1.880, 1.642 y 1.24 kilogramos por planta, respectivamente. Para peso de mota,
sobresalieron los ecotipos: Fino colorado y fifo claro con 3.95 a 2.96 g, respectivamente,
se encontró en la primera cosecha del arboretum A , en mayor número de ramas
fruteras con 43.797 ramas, con respecto a la cosecha soca , que solo formó 10.643
ramas fruteras. En el arboretum B , los resultados tuvieron la misma tendencia.
