156 Walang rice pest
Leptocorisa oratorius
F is a major pest of ladybugs group Hemiptera that destroy rice crops both in irrigated and tidal rice cultivation and invade almost every planting season. This pest
damage by sucking the mature grain in phase so that the grains into empty milk. Heavy attack can reduce the results to not be harvested. This pest also has the ability to spread is quite high, so it is able to cross the other
rice crops that mature milk mualai phase, the result will be global attack. The jam walang rice pest has the ability to produce eggs more than 100 eggs per female [7]. Walang rice pest life cycle of 35-56 days and
were able to lay 200-300 eggs per stem. Nesting capability that can cause an increase in the pest population quickly walang rice pest in paddy crop so this will increase attacks [8].
3.2. Walang rice pest control techniques
Measures used to control pests walang rice pest that is often done by farmers using insecticides they buy in the market stalls and farm to mixingmixing of various active ingredients this is because they want instant
these pests die . But is not that dead pest but walang rice pest natural enemies are dead so walang rice pest pest explosion so large that attack rice farmers reached 14 tails in a clump on things walang rice pest
economic threshold in integrated pest management concept is in an area of 1 there is a 15 meter tail walang rice pest. It is becoming a big problem and makes concern for farmers in the district of Muara Telang
particular and the resulting reduction in rice production.
Measures used to control walang rice pest using insecticides is the final step when another control is not able to handle it is not cutting edge solutions.
a. Use of traps. The use of materials from the snail stinging trap then strung on wire and soaked with insecticide are
made active organo-phosphate and installed at a distance of 5-10 in field so walang rice pest that came to visit and sucking the material and die because walang rice pest more attracted to the smell -these
smells than eating rice.
b. Use of natural enemies. Natural enemies are actually quite a lot walang rice pest in rice fields but because farmers often
spraying dead natural enemies of predator species predator species of spiders, beetles and grasshoppers karabit.
c. Use of mothballs. According Asikin and Thamrin walang rice pest control using mothballs are effective in controlling
pests walang rice pest. Application control tactic was made during the vegetative phase when rice bunting or until the grains of rice begin to harden that is by hanging mothballs that have been
incorporated into the wrapping of rags. Control tactics using the mothballs are rejected or repel pests coming walang rice pest because of the smell emitted by the substance contained in the lime mounting
distances ranging from 5 m in the rice plant. In this way the intensity of the damage can be reduced by walang rice pest ranged between 5-10.
d. Use biological control Using entomopathogenic fungi is based on research results Efendy et al [8], use of entomopathogenic
fungus origin swamp land of South Sumatera and
Metharizium
and
Beauveria
species by infecting befallen walang rice pest, befallen befallen infected decrease tends to show the movement and eating
infected befallen walang rice pest tends to stay away from the dead because Beuveria mushrooms and white indicates dry. Walang rice pest control using walang rice pest backfire. By capturing walang rice
pest then do mixed or extracts from walang rice pest because toxins inside walang rice pest and odor caused can reduce walang rice pest populations. Need to examine more about the impact and results.
