ABSTRACTION
In pattern plant one year [done/conducted]
[by] a farmer, maize [in] planting once or [is] twice depended from various
factor that is rainfall, availibility of water, farm type, other social factor
and price. Maize can be planted by monokultur and or tumpangsari [of] [at]
pattern plant one year which is a lot of determined by consideration of
agronomis and commodity price. [At] double pertanaman [of] lower pest attack
caused by [his/its] diversified [by] the crop, [is] so that happened [by] the
organism interaction that goes on in the form of physical and also interferensi
biologis. [At] first pertanaman maize with the pattern plant the paddy - maize
and paddy - ( maize + soy), Helicoverpa Armigera, and Mythimna separata
represent the dominant pest. Highest population [at] monokultur [of] [at] 58
HST, that is 14 egg item + 24 larva tail H. armigera and 43 larva tail M.
separata. Predator Chrysopa sp. and Orius sp. playing a part in to control
second [of] the dominant pest. [At] second pertanaman maize with the pattern
plant the paddy - maize - maize [of] [at] monokultur and paddy - ( maize + soy
- ( maize + green peanut) [at] tumpangsari [of] there are three especial pest
groaning that is penggerek bar O. furnacalis M. separata, and H. armigera.
Population O. furnacalis [is] not influenced by pattern plant existing.
Population M. separata and H. highest armigera about 66 day after planting (
HST). Population O. furnacalis and M. higher separata [at] compared to [by]
second pertanaman maize [of] first pertanaman maize, while H. armigera on the
contrary. Pattern plant the, natural enemy and also climate which playing a
part in above mentioned especial pest dynamics. explosion of Population of
Mythimna sp. having big opportunity [at] second pertanaman maize.
