“…Seekor kumbang mampu meletakkan telur sebanyak 90,44 ± 14,38 butir dengan masa oviposisi yakni 8,97± 0,89 hari. Jumlah ini lebih sedikit dari laporan Udiarto et al (2011) yakni 100 butir dengan mangsa B. tabaci. Menurut Chakraborty dan Korat (2014) betina C. transversalis dapat meletakkan sebanyak 173 butir dan maksimum 528 butir.…”

Biology and demographic statistics of lady beetle Coccinella transversalis Thunberg (Coleoptera: Coccinellidae) using Aphis gossypii (Hemiptera: Aphididae) as prey was studied in laboratory. Development of C. transversalis from egg to adult was 31.02±4.73 days. The egg stage lasted for 2.33±0.58 days. Larva stage has four instars, which lasted for 2.43±0.19 days (instar I); 2.53 days±0.19 (instar II); 2.64±0.04 days (instar III), and 2.77±0.21 days (instar IV). A female laid 90.44±14.38 eggs. Meanwhile, gross reproduction rate (GRR) of C. transversalis was 74.80 individuals per generation, the net reproduction rate (R0) was 18.22 individual per female per generation, the innate capacity for increase (rm) was 0.46 individual female per day, the mean generation time (T) 12.40 days, and the double population value (DT) was 1.51 days. IntisariMasa perkembangan pradewasa dan imago serta keperidian Coccinella transversalis (Thunberg) (Coleoptera: Coccinellidae) telah diteliti di laboratorium dengan menggunakan Aphis gossypii (Glover) (Homoptera: Aphididae) sebagai mangsa. Masa perkembangan C. transversalis sejak stadium telur hingga menjadi imago adalah 31,02±4,73 hari. Perkembangan larva terdiri dari empat instar, masa perkembangan instar I sampai IV berturut-turut adalah 2,43±0,19 hari; 2,53±0,19 hari; 2,64±0,04 hari, dan 2,77±0,21 hari, dengan masa pupa 3,18±0,77 hari. Umur imago betina C. transversalis lebih panjang jika dibandingkan dengan imago jantan yakni 15,14±1,90 dan 13,63±1,00 hari. Imago betina meletakkan telur setelah melewati masa pra oviposisi selama 2,67±0,58 hari. Masa oviposisi C. transversalis yakni 8,97±0,89 hari dengan jumlah telur yang diletakkan yakni 90,44±14,38 butir. Parameter demografi C. transversalis adalah laju reproduksi kotor (GRR) adalah 74,80 individu per generasi; laju reproduksi bersih (Ro) 18,22 individu per induk per generasi; laju pertumbuhan intrinsik (rm) sebesar 0,46 individu per induk per hari; masa rata-rata generasi (T) selama 12,40 hari; dan nilai pelipatgandaan populasi (DT) adalah 1,51 hari.

“…Tingginya kekayaan spesies artropoda musuh alami dapat meningkatkan kestabilan ekosistem sehingga tidak didominasi oleh fitofag (Latoantja et al, 2013), namun banyak faktor yang dapat menyebabkan ketidakstabilan ekosistem sawah, misalnya aplikasi insektisida sintetik yang terbukti banyak menyebabkan kematian artropoda musuh alami (Herlinda et al, 2008;Udiarto et al, 2012), misalnya penurunan kelimpahan dan keanekaragaman spesies artropoda permukaan tanah dari Famili Lycosidae, Lyniphiidae, Carabidae, dan Formicidae pada ekosistem sawah akibat aplikasi deltametrin (Winasa & Rauf, 2005).…”

Abundance and species richness of the predatory arthropods on paddy treated with Bacillus thuringiensis bioinsecticide. Application of bioinsecticide from bacterial entomopathogen has not been reported yet that can decrease abundance and species richness of predatory arthropods, such as spiders and predatory insects. This research was aimed to analyze the abundance and species richness of predatory arthropods paddy fields applied by B. thuringiensis bioinsecticide on paddy in fresh swamp area. Areas observed were 2 ha paddy field's at Situ Bagendit variety. Predatory arthropods inhabiting canopy were sampled using sweep but soil dwelling arthropods were trapped using pitfall traps. The result showed that abundance of spiders inhabiting canopy decreased significantly after B. thuringiensis bioinsecticide application on paddy compared to control without bioinsecticide but the abundance of predatory insects were not significantly affected by the bioinsecticide. Application of the bioinsecticide did not significantly affect the abundance and species richness of soil dwelling predatory arthropods, such as spiders and predatory insects.Key words: abundace, arthropod, paddy, species richness ABSTRAKKelimpahan dan kekayaan spesies artropoda predator pada tanaman padi yang diaplikasikan bioinsektisida Bacillus thuringiensis. Aplikasi bioinsektisida berbahan aktif bakteri belum banyak dilaporkan berdampak buruk terhadap kelimpahan dan keanekaragaman spesies artropoda predator, seperti laba-laba dan serangga predator. Penelitian ini bertujuan untuk menganalisis kelimpahan dan keanekaragaman spesies artropoda predator pada tanaman padi sawah lebak yang diaplikasikan bioinsektisida B. thuringiensis dan tanpa yang diaplikasikan bioinsektisida B. thuringiensis. Lahan yang diamati yaitu lahan padi sawah lebak yang ditanami varietas Situ Bagendit seluas 2 ha. Artropoda predator penghuni tajuk diamati menggunakan jaring serangga, sedangkan penghuni permukaan tanah menggunakan lubang jebakan. Dari hasil penelitian didapatkan bahwa kelimpahan laba-laba penguni tajuk menurun secara signifikan setelah aplikasi B. thuringiensis pada tanaman padi dibandingkan tanpa aplikasi (kontrol), namun untuk kelimpahan serangga predator penghuni tajuk tidak terpengaruh oleh aplikasi bioinsektisida tersebut. Aplikasi B. thuringiensis tidak berpengaruh nyata terhadap kekayaan spesies atropoda predator penghuni tanah, laba-laba dan serangga predator. Dengan demikian, aplikasi B. thuringiensis tidak menurunkan kelimpahan dan kekayaan spesies artropoda predator yang menghuni di permukaan tanah dan serangga predator tajuk.

“…is quite high for preying B. tabaci, Aphis gossipii, Empoasca sp. and S. litura (Suastika et al 2005;Udiarto et al 2012;Riaz and Naqvi 2014). Therefore, the presence of these predators needs to be maintained because they have a significant role in biological control.…”

The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9.8% as compared to chemical treatment. T4 was also more efficient than T5 because it uses less biological agents. The advantage of biological agents is compatible if they were used together with predators such as Oxyopes sp., Paederus sp. and Coccinella sp; and also Telenomus sp. and Trichogramma sp. parasitoids. On the other hand, the chemical pesticides (T6) killed all existing natural enemies. Therefore, T4 could be recommended for controlling mungbean pests and diseases.
