| Summary: | This research was aimed to know the determine the distribution of larval
populations of L. stigma on sugar cane plantations in Sleman. Observations carried
out by determining the location of population sampling in sugarcane plantations in
Sleman district in ten places (Sambiroto, Grenjeng A, Grenjeng B, Tempelsari A,
Tempelsari B, Njaplaksari, Pronanggan, Pundungrejo, Selokan, and Seturan ) of the
month of February to June. Observation parameters used are larvae (L. stigma), the
number of individuals (head/m2), depth (cm), and soil moisture (%). The results
showed that the patterns of larval dispersal L. stigma on sugar cane plantations in
Sleman were clustered. The highest number of individuals was found in Njaplaksari,
while those with the lowest number of larvae was on Tempelsari B. Soil with a high
content of dust fraction (29.81%) resulted in high number of larval populations of L.
stigma. Vertical mobility of larval L. stigma was influenced by soil texture class and
soil moisture. Larvae was tend to be found in shallow depth when the fraction of the
dust or soil moisture was higher. Otherwise, larvae was tend to be found deeper
when the fraction of the sand was higher. |
