“…The number of individuals from the Sleman population that survived was the highest and still Natality, mortality, and developmental time were three aspects that determine the capacity of a population to increase or are referred to as the intrinsic growth rate (Hidayat et al, 2017). Birch (1948) states that the value of the intrinsic growth rate (r) and the decrease in environmental resources can be caused by an increase in gross reproduction value (GRR) and net reproduction value (Ro).…”

Helopeltis bradyi Waterhouse has been reported to attack tea plantations in Batang District and cocoa plantations in Sleman District and Kulon Progo District. Information about the life parameters of H. bradyi reared using alternative feed cucumbers in the laboratory helps pest management efforts. This study aimed to determine the life demography of H. bradyi from two plants and three different locations. The study was conducted with cohort observations consisting of gross reproduction rate (GRR), net reproduction rate (Ro), intrinsic growth (r), average generation length (T), and population doubling time (DT) of three populations of H. bradyi. Results showed that there were differences in living individuals (ax), mortality, and life duration of the three H. bradyi populations. The survival type of the three populations of H. bradyi was classified as type IV. The survival of the three H. bradyi populations were influenced by their ability to adapt to new environments. From the three populations of H. bradyi observed, Sleman population survived longer because they had adapted to the rearing environment and were able to maintain the population numbers for two generations. Demographic parameters of H.bradyi from Sleman showed gross reproduction rate (GRR) of 88 individuals/generation, net reproduction rate (Ro) of .97 individuals/parents/generation, the increase in population rate (r) of 0.02 individuals/species/day, extended duration (T) of 39.50 days, and doubling time (DT) of 40.49 days.

“…Populasi berlipat ganda (DT) merupakan waktu yang dibutuhkan populasi serangga untuk menjadi berlipat ganda. Perlakuan D memiliki nilai DT terendah yaitu sebanyak 4,61 kali dibandingkan perlakuan A. Menurut Kurniawan (2019), nilai DT yang rendah dapat meningkatkan nilai laju reproduksi bersih (R0) dan laju pertambahan instrinsik (r). Sehingga dengan nilai DT yang rendah menunjukan semakin singkat waktu yang dibutuhkan populasi untuk berlipat ganda dan pertambahan populasi menjadi lebih cepat (Hutasoit et al, 2017).…”

Hermetia illucens L. (Black Soldier Fly) larvae are used as a source of high protein for animal feed, in cultivation they must produce larvae with fast growth and development in large numbers as well as imago with a high reproductive rate. The success factor from the type of feed given, because it can affect the growth and development of the larvae. The research to find a better type of feed for the growth and development of larvae. The research conducted from March 2022 to February 2023 at the Pesticide and Environmental Toxicology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The experiment used a completely randomized design with 4 treatments and 5 replications. The treatment used grain bran feed, rice bran with kale, bran with banana stems, and bran with chicken manure compost. The results showed that the type of grain bran feed with chicken manure compost produced better scores on net reproduction rate (2210.85 females/mother/generation), intrinsic rate of increase (46.43%), population doubling (3.6 days), proportion of live individuals (0.84 individuals), number of eggs (528.8 eggs), average weight (6.534 g), consumption rate (0.0112 g/day), relative consumption rate (0.0104 g/day), growth rate (…0,0123 g/day..), relative growth rate (0,0115 g/g/day), digestibility (3.1940%), efficiency conversion of food consumed (2.0033%), and efficiency consumption of digested food (2,2029%) with increase respectively 4.58 times, 9.63 times, 4.61 times, 2.1 times, 2.27 times, 3.11 times, 2 times, 2.03 times, 1.14 times, 1.16 times, 2.88 times, 1.98 times, and 3.10 times compared to rice bran feed.

Beauveria bassiana merupakan salah satu jenis cendawan entomopatogen yang termasuk dalam divisi Ascomycota, kelas Sordariomycetes, ordo Hypocreales dan famili Clavicipitaceae. B. bassiana dapat membunuh seluruh stadia serangga pada berbagai jenis hama tanaman dari ordo Homoptera, Hemiptera, Coleoptera, Lepidoptera, Orthoptera, Isoptera, Diptera, dan Hymenoptera. Efikasi B. bassiana dipengaruhi oleh berbagai jenis enzim yang dihasilkan yaitu: kitinase, protease, amilase, dan lipase yang berfungsi sebagai pendegradasi lapisan integumen serangga. Efikasi cendawan juga dipengaruhi oleh produksi toksin yang terdiri dari beauvericin, bassianin, bassiacridin, beauvericin, bassianolide, cyclosporine, oosporein, dan tenellin yang dapat mengganggu sistem syaraf dan membunuh serangga sasaran. Keunggulan B. bassiana bersifat ovisidal yang dapat menggagalkan penetasan telur selain membunuh stadia nimfa/larva maupun imago, sehingga dapat menekan perkembangan populasi dan menghambat terjadinya peledakan hama. Kelebihan lain B. Bassiana, yaitu bersifat endofit yang dapat menghambat perkembangan patogen tular tanah maupun penyakit karat daun (Phakospsora pachyrhizi), embun tepung (Microsphaera diffusa), dan embun bulu (Peronospora mansyurica). Cendawan B. Bassiana juga bersifat ramah lingkungan sehingga aman terhadap kelangsungan hidup musuh alami dan hewan ternak serta tidak mencemari sumber air maupun lingkungan. Aplikasi B. bassiana dapat menekan terjadinya resistensi maupun resurjensi. Waktu aplikasi B. bassiana dianjurkan pada sore hari dengan frekuensi aplikasi tiga kali. Cendawan B. bassiana prospektif untuk digunakan sebagai biopestisida dalam mengendalikan hama dan penyakit tanaman, ramah lingkungan, serta dapat digunakan sebagai alternatif pengganti pestisida sintetik.
