Abstract

ABSTRACT
THE INFLUENCE OF SOME KIND OF FORESTRY FEED PLANTS TO THE
QUALITY AND QUANTITY OF Cricula trifenestrata Helf COCOONS
The research aims to look at the influence of some types on liking of forestry plants
feed (preference), life cycle, and the quantity and quality of gold silkworm cocoons C.
Trifenestrata. This research was conducted from July to October 2015. Data collection was
performed by the method of completely randomized design (CRD). Data collection was
performed by completely randomized design (CRD) method.
Specifically to see the effect on the quantity of cocoon, research using the completely
randomized design (CRD) method. Observation is done by counting the number of larvae on
each type of feed. Data were analyzed to find the value of the average percentage for each
type of feed.
The results showed that avocado feed into the main host of C. trifenestrata for
preferred and easy to digest, and provide the best effect against the liking (preference) that is
: 24.5%, while eating cinnamon lower than the avocado feed 22.2%, compared to eating
avocado and cinnamon Nantu feed have a lower preference level that is 19.2%, a lower level
compared to eating avocado, cinnamon, Nantu feed, indicated by the cempaka feed that is
17.7%, while feed with the lowest preference level is mahogany feed with 16.7%. The
Average of long life cycle of insects that are kept on each type of feed as the host,
respectively : Cempaka (61,7 days), Mahogany ( 55,9 days), Nantu (49,3 days), Avocado
(72,3 days), dan Cinnamon (64,7 days). Avocado feed give the best effect on the quantity of
cocoons prodeced, that is: cocoons weight (95,56 g), heavy leather cocoons (13,9 g), and
percentage cocoons leather (27,07 g). Avocado feed give the best effect on the quality of
cocoon formed (shape and cocoons colour)
