ABSTRACT
NIKOLAS NIK. 2009. Study of Ecological Aspect of Locust migratory
(Locusta migratoria L.) (Orthoptera : Acrididae) and the Application of Bio-Inseticide in Regency of Timor Tengah Utara and Belu Province Nusa Tenggara Timur supervised by DADANG and IDHAM SAKTI HARAHAP
セ ッイョ@ is a staplefood, other than rice, for people of Nusa Tenggara Timur.
This
&rlP
is commonly cultivated in dry land area together with others crops suchas rici cucumber, peanut, etc. In 2007/2008 migratory locust, (Locusta
migratlJrfa L.,) attacked corn and rice plantation in Kabupaten of Timor Tengah Utara -6nd Belu and damaging the majority of corn and rice plantation. Due to this plagueiiifood supplies for local people were threatened. In order to control this pest, a ltudy of ecology of migratory locust and their control method using Green
gオ。イ、セ oo@ ULV (contain spores of Metarhizium anisopliae L.) were conducted. The objctives of these researches were 1) to study the characteristic of migratory locust habitat; 2) to study the effect of soil moisture on locust egg hatching, 3) to
study

morphometry in relation to their phase development, 4) to study theefficaci of Green Guard® 300 UL V (GG) against migratory locust nymphs .

using clay, clay sandy loam, and sandy loam with soil moisture of40%, セ EL@ 80% and 100%. In morphometric studies the length of elytra, the
lengthl hind leg femur, and the width of head were measured. Efficacy of Green
Guard 0300 UL V against 1. migratoria conducted using GG 100%, GG 1 :50, GG
1: 1000?-GG 1 :3000 (in vegetable oil) and control. The result showed that the highest egg pods laid was found at the area covered with grass in sandy clay soil with the altitude between 0-100 m above sea level. The highest percentage of egg
hatching was found at clay sandy loam soil with the of moisture 80%.
Morphometric studies revealed that between February to April 2009 there were more solitary individuals than transient, however some individuals belong to gregarious phase. The efficacy test of Green Guard® 300 UL V showed that the highest nymphs mortality was found on the concentration of 100% GG.
