let $r$ be a commutative ring with identity. an ideal $i$ of a ring $r$is called an annihilating ideal if there exists $rin rsetminus {0}$ such that $ir=(0)$ and an ideal $i$ of$r$ is called an essential ideal if $i$ has non-zero intersectionwith every other non-zero ideal of $r$. thesum-annihilating essential ideal graph of $r$, denoted by $mathcal{ae}_r$, isa graph whose vertex set is the set...

Abstract The objective of this study was to evaluate the capacity as bioindicators litter arthropodofauna in pasture restoration Atlantic Forest Biome. Areas native forest under natural regeneration, and pastures treated with different ecological techniques were evaluated, pitfall traps. sampling period from April/2017 October/2018, bimonthly.

Penelitian ini bertujuan untuk mendeskrpsikan keanekaragaman jenis dan Kemelimpahan serangga tanah di Cagar Alam Panua Gorontalo. Objek penelitian adalah yang terdapat kawasan cagar alam panua gorontalo. Metode digunakan metode Pitfall trap. Data diperoleh dianalisis menggunakan deskriptif kuantitatif yakni menghitung nilai (Hl = -∑ (Pi lon Pi) kemelimpahan (KRi ∑ Ni/N x 100 %). Hasil pada huta...

An evaluation of several insecticides, namely, 0.01% fipronil, 0.05% indoxacarb, and 2% boric acid in liquid bait formulations were carried out against field populations of the longlegged ant, Anoplolepis gracilipes (Fr. Smith) (Hymenoptera: Formicidae). The baits were formulated in brown cane sugar solution (50%, wt:wt) and placed in an experimental bait station. Each bait was evaluated agains...
