<p>Dalam beberapa tahun terakhir tanaman jambu mete di NTB diserang oleh wercng pucuk. yang semula dikenal sebagai Lawana sp. atau L. Candida. Penamaan tersebut tidak tepat karena tidak didukung oleh penelitian taksonomi yang memadai. Penelitian ini bertujuan untuk mengidentifikasi serangga wereng pucuk tersebut berdasarkan ciri morfologi serta mcmpelajari beberapa aspek biologinya. Identiikasi dilakukan di Balai Penelitian Tanaman Rempah dan Obat (Balittro), Bogor dan Pusat Penelitian dan Pengembangan Biologi LIPI, Cibinong dari September - Nopember 2002, sedang pengamatan lapang di lakukan di daerah Lombok, NTB pada tahun 2001-2002. Dai identifikasi terhadap serangga contoh yang diambil dai beberapa lokasi di Lombok, NTB dapat disimpulkan bahwa wereng pucuk jambu mete tersebut adalah Sanurus indecora Jacobi. Beberapa cii utama serangga ini antara lain pada bentuk dan venasi sayap depan (legmen), jumlah spina (duri) lateral pada tibia kaki belakang, bentuk carina pada frons (muka bagian atas) dan bentuk aedeagus (genitalia jantan). Hasil pengamatan di lapangan menunjukkan bahwa daerah sebaran serangga tersebut terdapat di daerah Lombok dan Sumbawa, mempunyai banyak inang antara lain mangga, jeruk, krotalaria, jarak, rambutan, bougcnville dan nangka, siklus hidup 3 -4 minggu, seekor imago mampu meletakkan telur 80 butir atau lebih serta mempunyai beberapa musuh alami antara lain parasitoid telur, Aphanomerus sp. dan jamur entomopatogen, Synnematium sp. dan atau Hirsulella citriformis.</p><p>Kata kunci: Wereng pucuk, jambu mete, Sanurus indecora</p><p> </p><p><strong>ABSTRACT</strong></p><p><strong>Identiication of cashew shoot hopper, S. indecora and its biological aspects</strong></p><p>In the last few years, cashew plantations in West Nusa Tenggara has been attacking by shoot hopper, which formerly known as Lawana sp. or L.

Embryonic And Larval Development

Early ontogeny is still the least well-known part of the molluscan life cycle, despite its unarguable significance in ecology, biogeography, and evolution. The past decade has seen an acceleration in biological research on molluscan embryonic and larval development, and paleontologists have recently begun to explore this field as well. Although the very earliest phases of ontogeny are inaccessible to the paleontologist, a remarkable amount of information can be derived from the preserved details of larval shell morphology. The fossil record thus affords rich opportunities to study directly the development of extinct species, both from a phylogenetic standpoint and for tracing the evolutionary and biogeographic effects of these early stages in life history. Access to long-extinct clades and an ability to document rates and patterns of evolution allow paleontologists to test hypotheses that can be addressed only indirectly using Recent data. Here I will emphasize these paleontological aspects of molluscan development (see also Jablonski and Lutz, 1983); for the more strictly biological aspects of reproduction and embryology, see Giese and Pearse (1977, 1979), Verdonk et al. (1983) and Tompa et al. (1984).

Abstract An invasive population of spotted lanternfly (SLF), Lycorma delicatula White, was first noted in North America in Pennsylvania in 2014, and by September 2020 populations had spread to six additional states. To develop a biocontrol program to aid in the management of the pest, exploratory surveys for SLF natural enemies in its native range were carried out in 27 provinces and other administrative regions of China from 2015 to 2019. Naturally laid egg masses were collected and sentinel SLF egg masses were deployed to attract egg parasitoids, and yellow sticky traps were used to collect SLF nymphs to discover and determine the parasitism rates of nymphal parasitoids. Results show that SLF is widely distributed in China (22 provinces and regions) and that the population densities in northeast China are higher than in southern and western China. An egg parasitoid, Anastatus orientalis Yang (Hymenoptera: Eupelmidae), and a nymphal parasitoid, Dryinus sinicus Olmi (Hymenoptera: Dryinidae), were collected. Anastatus orientalis was reared from SLF eggs in seven provinces in China with parasitoid emergence rates ranging from 4.0 to 15.5% (or 17.6 to 37.3% if including only egg masses that had at least some parasitism). There were significant differences in parasitoid emergence rates between sites associated with factors including habitat and host plants. Dryinus sinicus was discovered in eight cities across six provinces. The percentage of SLF nymphs parasitized by D. sinicus were 31.1, 23.3, and 0% in Tai’an, Shandong Province, Beijing City, and Yan’an, Shaanxi Province, respectively. These two parasitoids are promising natural enemies that are being considered as potential biocontrol agents of invasive populations of SLF.

Introduction: Hamadryas feronia feronia, which mimics the bark of trees and often makes attention-grabbing sounds when flying, has good potential for bio-business (export, handicrafts and tourist breeding centers). However, its biological aspects are still unknown, which hinder its captive breeding. Objectives: To determine the biological aspects of feeding, oviposition behavior, life cycle and natural enemies of Hamadryas feronia feronia L. in San Rafael-Indiana, Loreto, Peru. Methods: Sampling was conducted from January 2018 to December 2019 in the community of San Rafael, Amazon River. Adults were observed during the day, their food plants, oviposition behavior, biological cycle and natural enemies were recorded. The life cycle was evaluated in the laboratory, using 20 eggs recently deposited on the leaves of their host plant. Results: The larvae of H. feronia feronia feed on the leaves of Dalechampia juruana and the adults feed on the bark sap of Cedrela odorata, Spondias mombin, Uncaria guianensis and the fermented fruits of Syzygium malaccense and Pouteria caimito. Adults fly on sunny days, males emit a loud sound when flying. Females prior to oviposition flit irregularly around their host plant between 8.00 and 14.00 h and deposit their eggs on the upper and underside of leaves in isolation, most frequently on the underside. The duration of the cycle from egg to adult was 28.24 days. The average egg period was 3.75 ± 0.40 days. The larvae passed through five larval instars: the first instar 3.21 ± 1.03 days, the second 2.78 ± 0.73 days, the third 2.67 ± 0.77 days, the fourth 3.22 ± 0.81 days, and the fifth 4.61 ± 0.70 days. The prepupal period lasted 1.33 ± 0.49 days and the pupal period 6.67 ± 0.80 days; the adults hatched between 10:00 to 11:00 h. Adult males lived on average 31.80 ± 3.29 days, the female 42.00 ± 2.14 days and their eggs were parasitized by a microhymenopteran (Scelionidae). Conclusions: This study allowed to know the biological aspects of H. feronia feronia identifying its food plants of both larvae and adults, its oviposition behavior, as well as it has been determined that it has a relatively short biological cycle with a period of less than one month and its eggs are consumed by a small Hymenoptera that can hinder its production. This work provides necessary information to develop the breeding of H. feronia feronia, oriented to its conservation, environmental education and biotrade (tourism and handicrafts) in the Peruvian Amazon.

<p>Jambu mete (Anacardium occidentale L.) merupakan salah satu komoditas ekspor. Salah satu kendala dalam produksinya adalah serangan hama. Di Nusa Tcnggara Barat (NTB), Sanurus indecora telah menjadi isu utama dan dianggap sebagai salah satu hama yang scrius menyerang tanaman jambu mete. Untuk mengetahui bioekologi S. indecora dan pengaruh scrangannya terhadap kchilangan hasil jambu mete telah dilakukan penelitian di pertanaman jambu mete di Dusun Sambik Rindang, Desa Salut, Kecamatan Kayangan, Kabupaten Lombok Barat, NTB dan di laboratorium Entomologi, Balai Penelitian Tanaman Rempah dan Obat, Bogor dari April sampai Oktober 2003. Penelitian ini terdiri atas dua kegiatan penelitian yaitu di lapang dan di laboratorium. Kegiatan di lapang adalah untuk mengetahui pengaruh serangan S. indecora terhadap kchilangan hasil, ekobiologi, dan musuh alami, sedang kegiatan laboratorium ialah tingkat parasitasi Aphanomerus sp. pada telur S. indecora. Penelitian pengaruh serangan S. indecora terhadap kehilangan hasil jambu mete dilakukan dengan perlakuan pucuk jambu mete yang dikurung dengan kurungan kasa dan yang tidak dikurung. Perlakuan yang dikurung ialah 25 pucuk jambu mete yang tidak terserang (tanpa) S. indecora yang telah mempunyai 5-12 bunga hermaprodit. Sebagai perlakuan yang tidak dikurung ialah 13 pucuk belum terserang S. indecora dan 12 pucuk jambu mete dengan kisaran bunga hermaprodit seperti tersebut di atas yang telah terserang S. indecora. Pengamatan dilakukan terhadap perkembangan bunga mete, awal serangan pada pucuk dan berat gclondong. Untuk mengetahui sebaran 5. indecora dilakukan survei di tiga kapubaten di Propinsi NTB yaitu Lombok Barat, Lombok Timur dan Sumbawa dengan metode sampling. Penelitian biologi dilakukan terhadap 60 nimfa yang baru keluar secara individu dan diamati perkembangannya setiap hari. Penelitian untuk mengetahui musuh alami selain parasitoid telur, dilakukan pengamatan pada 10 pucuk jambu mete yang terserang 5. indecora. Pengamatan dilakukan tiap minggu. Tingkat parasitasi Aphanomerus sp. dihitung dengan mengamati parasitoid yang keluar dari 100 kelompok telur S. indecora setiap hari. Hasil penelitian di Dusun Sambik Rindang, Desa Salut, Kecamatan Kayangan, Kabupaten Lombok Barat, NTB menunjukkan bahwa serangan S. indecora menyebabkan kehilangan hasil jambu mete sebesar 57.83%. Hasil survei di tiga kabupaten yaitu Lombok Barat, Lombok Timur dan Sumbawa menunjukkan bahwa S. indecora ditemukan di tiga kabupaten tersebut. Dengan demikian 5. indecora merupakan salah satu hama utama jambu mete. Dari penelitian biologi, lama stadia telur S. indecora ialah 5-9 hari. Stadia nimfa terdiri dari 6 instar, total masa nimfa adalah 42 - 49 hari dan lama masa imago (serangga dewasa) ialah 5 -6 hai. Selain Aphanomerus sp. (Hymenoptera: Platygasteridae), beberapa musuh alami lainnya yang ditemukan di lapang yaitu laba-laba (Arachnida), kumbang Coccinellidae (Coleoptera), Braconidae, Chaleididae (Hymenoptera), belalang sembah (Orthoptera: Mantidae) dan Bocha amphilhoa (Diptera: Syrphidae). Persentase telur terparasit sebesar 9.78%. Persentase telur menjadi nimfa 8.32% dan telur yang tidak menetas 81.90%.</p><p>Kata kunci : Jambu mete, bioekologi, Anacardium occidentale L , Sanurus indecora, hama, musuh alami, kehilangan hasil</p><p> </p><p><strong>ABSTRACT</strong></p><p><strong>Bioecology of Sanurus indecora and the effect of its infestation on the loss of cashew yield</strong></p><p>Cashew (Anacardium occidentale L.) is an export commodity. One of the constraints in cashew production is pest attack. In West Nusa Tenggara (NTB), a latid, S. indecora had become a serious issue and was suspected as one of serious pests attacking cashew plant. Experiments to determine the bioecology of 5. indecora and the yield loss of cashew due to the insect infestation were carried out in Sambik Rindang, Salut Village. Kayangan, Lombok Barat District, West Nusa tenggara and in the laboratory of Entomology, die Indonesian Spice and Medicinal Crops Research Institute, Bogor from April to October 2003. Field activities were aimed to find out the effect of S. indecora infestation on yield loss of cashew, ecobiology, and natural enemies. Laboratory activity included parasitization stage of Aphanomerus sp. in 5. indicora. Study on the yield loss of cashew due to S. indecora was carried out by caging and uncaging shoots. Twenty two shoots with 5-12 hermaphrodite lowers were caged 13 shoots with 5-12 hermaphrodite lowers which imatially not attacked by S. indecora and 12 shoots with 5-12 hermaphrodite flowers already attacked by S. indecora. Observations were done on the development of cashew lowers, initial attack on shoots and weight of seeds. To determine the distribution of 5. indecora. a survey was conducted in three districts in West Nusa Tenggara Province namely West Lombok, East Lombok and Sumbawa, using sampling methods. Biology experiment was conducted by caging 60 newly nymphs individually on cashew seedlings and its development was observed every day. To determine natural enemies beside egg parasitoid, observation was conducted on 10 shoots attacked by S. indecora. Parasitization of Aphanomerus sp. was counted by observing natural enemies emerged from 100 egg clusters of 5. indecora. Observation was carried out once a week. Results of the experiment in Sambik Rindang, Salut Village, Kayangan, Lombok Barat District, West Nusa Tenggara showed that the latid caused 57.83% yield loss of cashew. Results of survey in three districts namely West Lombok, East Lombok and Sumbawa, showed that S. indecora was found in those three districts. Therefore, It can be concluded that 5. indecora was a serious pest of cashew plant. The biology experiment showed the duration of its eggs was 5-9 days, nymphs was 42 - 49 days, and adults was 5-6 days. The nymph consisted of six instars. Beside Aphanomerus sp. (Hymenoptera: Platygasteridae), the natural enemies found in the field were spiders (Arachnida), "lady beetle" (Coleoptera: Coccinellidae), Braco-nidae, Chaleididae (Hymenoptera), mantid (Orthoptera: Mantidae) and Bocha amphilhoa (Diptera: Syrphidae). The parasitization of Aphano-merus sp. was 9.78%. The eggs hatched to be nymphs were only 8.32% and the eggs did not hatch were 81.90%.</p><p>Key words: Cashew, Anacardium occidentale L., bioecology.

Chlosyne lacinia saundersii (Doubleday) is a polyphagous lepidopteran that produces a great defoliation in its host plants. The objective of this work was to determine the development and survival time of C. lacinia saundersii and to report aspects of its natural history on “Cuban grass” Tithonia tubaeformis (Jacq.) Cass. (Asteraceae). Caterpillars from the field were kept in cages in a rearing chamber under controlled conditions and fed with leaves of T. tubaeformis until adults’ emergence. To the latter, a honey solution and T. tubaeformis flowers was given. The life cycle duration was 48 days (egg: 8.0 days; larva: 24.9; pupa: 6.9 days; adult: 8.3 days) with six larval stages. The survival of each stage of development was high (> 70%) but considering the period from egg to pupa, only 52% of the individuals reached adulthood. Larval gregariousness was observed. In relation to the sexes there is a predominance of females (1.1:1). Female pupae were heavier than males. This work represents the first contribution to the knowledge of the biology of C. lacinia saundersii under laboratory conditions on T. tubaeformis. Cuban grass is confirmed as a new alternative host plant for C. lacinia saundersii

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

Mites have hostplant specifications or host plants. Mites can be destructive and deadly of which is the host plants a mango crop. Mites on mango crops will cause the leaves yellow and fall off prematurely. This is will lead to the disruption of the productivity of mango. It is necessary for research to identify the mites that infect the mango crop. The method is carried out by direct observation. Mites were taken from the surface of mango leaves later in preservation with several levels of concentration of alcohol, and polyvinyl laktofenol. Then, observed under a microscope and documented for identification purposes. Mites on the leaf surface of manalagi mango (<em>Mangifera indica</em>) found two species, it is <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> (Family: Tetranychidae, Superfamily: Tetranychoidea). <em>Oligonychus</em> sp. hallmark is rounded body shape like a spider, with a body is transparent and there are two long seta on posterior part. While <em>Oligonychus ilicis</em> has a characteristic elongated rounded body shape, red, and there is a short posterior seta. <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> live as parasites on the surface of mango leaves that can lead to wrinkled leaves, yellow and to fall. <em>Oligonychus</em> life cycle starts from the eggs develop into Nympha and then adult.
