Natural Enemies Conservation: The Role of Neem-seed Extracts for Conservation Used Cotton Insect Pest Control. Insects associated with cotton plant are numerous, as the bears extrafloral nectar. More than 90 species natural enemies reported and identified. They could manage pest, keeping pest population is under action threshold level when their presence considered in scouting concept. However, most farmers insecticide-spray-minded people who think that insecticide sprays a must cultivation....

Insects visit flowers not only to forage for nectar or pollen but also search hosts prey, and look suitable habitats breeding sites. In oil palm flowers, it has been documented that all flower-visiting insects are pollinators, some recognized as predators, parasitoids saprophages, which may affect the abundance persistence of weevil pollinating palm, Elaeidobius kamerunicus. We studied community investigated covariation between E. kamerunicus other dominant species. Ecological research was...

In this study, technical lignin from black liquor was used as a pre-polymer for the preparation of bio-polyurethane (Bio-PU) resins. Briefly, isolated fractionated using ethyl acetate (EtAc) and methanol (MeOH). The liquid fractions lignin, such lignin-EtAc (L-EtAc) lignin-methanol (L-MeOH), were mixed with 10% polymeric isocyanate (based on weight fractions) to obtain Bio-PU lignin-derived resins characterized several techniques. obtained then modify ramie fibers vacuum impregnation method....

Abstract Oil palm plantations are typically managed in a monoculture system over large areas. This contributes to biodiversity loss and promotes pest outbreaks by reducing natural enemies. However, ecosystem functions oil vary spatially temporally can still support under certain conditions. We conducted study on the species richness, abundance composition of enemies investigated factors influencing enemy communities at both local landscape scales. selected 12 sites an plantation Central...

Abstract The citrus psyllid, Diaphorina citri , is a recognized vector of the devastating Huanglongbing (HLB) disease in plants, posing significant threat to global production. As climate change continues influence agroecological conditions, comprehending population dynamics this imperative for effective management. This study delved into relationship between variations and D. infestation patterns tangerine orchards from January December 2018. Leveraging dataset 12 monthly observation sets,...

We investigated experience acquisition (alpha‐conditioning) by females of the parasitoid Trichogramma australicum using host eggs noctuid moth Helicoverpa armigera (Hübner). compared acceptance a egg with different levels ovipositional experience. The level was designated standard oviposition sequence: (1) contact (C); (2) examination (E); (3) drilling (D); (4) full insertion (FI); and (5) (O). Each treatment consisted single level, but together these consituted qualitative behavioural...

For many years, agricultural intensification and exploitation has resulted in biodiversity loss threaten ecosystem functioning. Developing strategies to bridge human needs health for harmonization of is a major concern ecologist agriculturist. The lack information on species diversity natural enemies how utilize them with integration habitat management that can renovate ecological process was the main obstacle. Parasitoids, group enemies, play very important role regulating insect pest...

Teacher’s self-efficacy is a specific phenomenon that can be seen as one of the contributors to process learning and effective teaching. Teacher was investigated at two Senior High Schools (SMAN 1 SMAN 2) in Kendari, proved its importance interest-based classes senior high schools Kendari. Findings revealed major methods employed research study: 1) interviews conducted form an open interview with 5 teachers; observation focused on teachers teaching materials, classroom management, well...

Tritrophic interaction among host plant-herbivore-parasitoid involves chemical cues. The infested plant by herbivores has been reacted to produce volatiles which is a cue used the herbivore parasitoids for location. These can be developed enhance natural control of insect pests, especially optimally use parasitoids. Egg are biocontrol agents that play an important role in herbivores. This research tritrophic model rice plant-brown hopper (BPH)-egg parasitoid BPH. Research on analysis cues...

Serat alam yang berasal dari tanaman non-kayu dikategorikan menjadi tiga kelompok yaitu serat buah, batang dan daun.  Masing-masing jenis tersebut memiliki karakteristik berbeda.  Karakter kimia, fisik, maupun dinamik diperlukan untuk pengembangan pemanfaatannya sebagai bahan baku industri strategis berbasis serat.  Penelitian ini dilakukan menganalisis kimia buah (kapas), (abaka), daun (sisal), serta membahas peluang dalam alam. Informasi mengenai dasar pemanfaatan strategis. Data juga...

Tanaman dapat menghasilkan senyawa volatil sebagai sarana komunikasi intra- atau inter- spesies. yang terinfeksi herbivora akan memproduksi mekanisme pertahanan tidak langsung menarik musuh alami tersebut. Analisis senyawa-senyawa diproduksi oleh tanaman padi akibat infestasi telur wereng batang coklat (WBC) dilakukan untuk mengidentifikasi komponen penyusun berpotensi atraktan bagi parasitoid WBC, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae). Kegiatan penelitian ini...

We produced an ethogram for and investigated effects of physiological condition experience on oviposition behaviour Trichogramma australicum Helicoverpa armigera eggs. The data, coupled with the ethogram, have enabled establishment standard behavioural categories which can be used to assess acceptability H. eggs T. reared in vitro or other species. Physiological experiential conditions were using females three different ages (0–24, 24–48 48–72 h old), two types sexual states (mated unmated)...

ABSTRACT Biotypes of Trichogramma australicum were reared on artificial diet “A”, Helicoverpa armigera (Hübner) (natural host) eggs and Sitotroga cerealella (Olivier) (factitious eggs. We evaluated the quality these biotypes by comparing their oviposition behaviour reproductive performance H. Female T. in vitro accepted for displayed similar behavioural components to females natural hosts. However, handling time during from rearing was significantly longer than host because needed a feeding....
