ABSTRACT

Insect Diversity On Tomato Flowers (Lycopersicon esculentum Mill.) in
Organic Agriculture. Study on the diversity of insect visitors on tomato
flowers were conducted at Bina Sarana Bakti (BSB) organic farm, Cisarua,
West Java. Diversity of insects were observed by observational method, an
10 m2 area of tomato plants in the morning, mid-day, and afternoon.
Observations were conducted during 20 days. Diversity of visiting insects
were analyzed by Shannon diversity and its evenness. Similarity of visiting
insects between time of observations were analyzed by Jaccard similarity
index. In organic farm, insect visitors of tomato plants consist of six orders
belonging to eight species. Insect visitors of tomato flowers were dominated
by Thrips sp. (Thysanoptera) and Hylaeus sp. (Hymenoptera). Hylaeus sp.
was a main pollinator of tomato plants. Diversity of insect visitors in the
morning and mid-day was higher than in the afternoon. Evenness of insect
visitors of tomato flowers between observation times were relatively equal.
KEYWORDS: Diversity, insect visitors, tomato, organic farm.

[JURNAL] IMPLICATION OF TYPES OF FEEDS COMBINED GOAT MANURE FOR PREFERENCE BLACK SOLDIER FLY (BSF) : Hermetia illucens L. Indri Indri, Sylvia Sjam, Ahdin Gassa, Vien SD Departement of Plant Pests and Diseases, Hasanuddin University, South Sulawesi, Indonesia

  IMPLICATION OF TYPES OF FEEDS COMBINED GOAT MANURE FOR PREFERENCE BLACK SOLDIER FLY (BSF) : Hermetia illucens L.           Indri Indri, Sylvia Sjam, Ahdin Gassa, Vien SD   Departement of Plant Pests and Diseases, Hasanuddin University, South Sulawesi, Indonesia Abstract Hermetia illucens L. (Diptera: Stratiomydae) called black soldier fly (BSF) has an important role in the degradation of organic waste or bioconversion activity. The current study compared some types of feeds to preference BSF to eggs laid and the implication of the numbr of larvae and the size of pupae produced, the persentage of larvae that became adults. Type of feeds is rice bran, mixture of fruits waste, agricultural waste, vegetable waste and household waste. The type of feeds mixed with goat mature. The study reports that Black Soldier Fly (BSF) produced the hightest number of egg colonies in household waste (6 colonies) then vegetable waste (5 colonies)...

EFEKTIVITAS EKSTRAK METANOL KULIT BAWANG MERAH (Allium cepa L.) DAN KULIT BAWANG PUTIH (Allium sativum L.) DALAM PENGENDALIAN ULAT GRAYAK JAGUNG Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae)

 ABSTRAK  SUKMAWATI (G011181049) .  Efektivitas Ekstrak Metanol Kulit Bawang Merah ( Allium Cepa  L.) Dan Kulit Bawang Putih ( Allium Sativum  L.) Dalam Pengendalian Ulat Grayak Jagung  Spodoptera Frugiperda  (J. E. Smith) (Lepidoptera:  Noctuidae ) Spodoptera frugiperda (J. E. Smith) merupakan hama eksotik dan termasuk hama baru di Indonesia. S. frugiperda menyerang titik tumbuh dan mengakibatkan kegagalan produksi tanaman jagung. Pengendalian S. frugiperda menggunakan pestisida nabati sangat diperlukan guna mengurangi banyak dampak buruk yang ditimbulkan oleh penggunaan pestisida sintetik. Tujuan penelitian ini untuk mengetahui konsentrasi ekstrak limbah kulit bawang merah dan bawang putih terhadap mortalitas larva S. frugiperda. Penelitian ini dilaksanakan di Laboratorium Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Hasanuddin. Penelitian ini berlangsung Juli 2021 hingga April 2022. Metode penelitian menggunakan Ranca...
