“…For instance, regular use of pesticides can result in the pest becoming resistant, thus making future management a more difficult task [8]. Another unwanted side effect is that the pesticide can have lethal or sub-lethal effects on natural enemies [158] which can cause a resurgence in the pest population or a secondary pest to emerge.…”

Pest insects pose a significant threat to food production worldwide resulting in annual losses worth hundreds of billions of dollars. Pest control attempts to prevent pest outbreaks that could otherwise destroy a sward. It is good practice in integrated pest management to recommend control actions (usually pesticides application) only when the pest density exceeds a certain threshold. Accurate estimation of pest population density in ecosystems, especially in agro-ecosystems, is therefore very important, and this is the overall goal of the pest insect monitoring. However, this is a complex and challenging task; providing accurate information about pest abundance is hardly possible without taking into account the complexity of ecosystems' dynamics, in particular, the existence of multiple scales. In the case of pest insects, monitoring has three different spatial scales, each of them having their own scale-specific goal and their own approaches to data collection and interpretation. In this paper, we review recent progress in mathematical models and methods applied at each of these scales and show how it helps to improve the accuracy and robustness of pest population density estimation.

ABSTRAKTanaman dapat menghasilkan senyawa volatil sebagai sarana komunikasi intra-atau inter-spesies. Tanaman yang terinfeksi herbivora akan memproduksi senyawa volatil sebagai mekanisme pertahanan tidak langsung yang dapat menarik musuh alami herbivora tersebut. Analisis senyawa-senyawa volatil yang diproduksi oleh tanaman padi akibat infestasi telur wereng batang coklat (WBC) dilakukan untuk mengidentifikasi komponen penyusun senyawa volatil yang berpotensi sebagai atraktan bagi parasitoid telur WBC, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae). Kegiatan penelitian ini merupakan tahap awal dari pembuatan formula atraktan parasitoid WBC, meliputi ekstraksi senyawa volatil dari batang padi yang tidak terinfestasi dan terinfestasi telur WBC dengan menggunakan pelarut aseton dan n-heksana, analisis komponen senyawa volatil dengan menggunakan gas kromatografi spektroskopi massa (GC-MS), dan bioassay perilaku orientasi parasitoid terhadap senyawa volatil dengan metode olfaktometri. Metode ekstraksi yang digunakan adalah teknik maserasi dan ekstraksi kontinyu yang diikuti dengan pemekatan. Bioassay perilaku orientasi A. nilaparvatae dilakukan dengan menggunakan olfaktometer tabung Y dan untuk setiap lot bioassay digunakan 30 parasitoid telur yang diulang 3 kali. Hasil analisis menunjukkan bahwa senyawa volatil yang terdapat pada ekstrak tanaman padi yang terinfestasi telur WBC terdiri atas 16 komponen. Komponen dengan proporsi tertinggi pada metode dengan pelarut aseton adalah 2-Pentanon, 4-hidroksi-4-methil (19,9%), sedangkan dengan pelarut n-heksana adalah asam heksanadioat, dioktil ester (65%). A. nilaparvatae menunjukkan respon positif terhadap ekstrak tanaman padi yang terinfestasi telur WBC sehingga senyawa volatil yang terdapat pada ekstrak tanaman padi yang terinfestasi telur WBC dapat dimanfaatkan sebagai atraktan A. nilaparvatae untuk mendukung pengelolaan hama padi yang ramah lingkungan.Kata kunci: volatil, atraktan, Nilaparvata lugens, parasitoid ABSTRACTPlants produce volatiles as communication cues intra-or inter-species. Infested plants by herbivores will produce volatiles as indirect defense mechanism that attracts natural enemies of

“…In spite of these advantages, research has revealed lethal and sublethal effects of seed treatments on non‐target organisms . Beneficial arthropods may be exposed via the direct consumption of pollen and nectar of plants grown from treated seed, by consuming prey or hosts contaminated by feeding on such plants or when they consume the active ingredient via ingestion of plant sap .…”
