چکیده
Penelitian ini bertujuan untuk mengetahui pengaruh insektisida botani ekstrak daun sirsak dan IGR diflubenzuron terhadap mortalitas perkembangan kepik hijau (Nezara viridula). dilaksanakan pada bulan Oktober hingga Desember 2018 di Laboratorium Hama Tumbuhan Bioteknologi Fakultas Pertanian, Universitas Lampung. Perlakuan disusun dalam Rancangan Acak Kelompok (RAK) yang terdiri atas 5 perlakuan yaitu kontrol (P0), konsentrasi 4% (P1), 8% (P2), 12% (P3), 0,1% (P4). Setiap diulang tiga kali digunakan sebagai kelompok. satuan percobaan menggunakan 10 ekor nimfa N. viridula instar II. Variabel diamati adalah (umur instar, kecacatan nimfa, imago terbentuk). Hasil penelitian menunjukkan bahwa aplikasi berpengaruh nyata menghambat viridula. Insektisida berbahan aktif lebih cepat menyebabkan kematian (100%) HSA dibandingkan (87,67%) 21 HSA. memiliki serangga Nezara terjadinya serta terbentuknya imago. Hal masing-masing efektif hama

Demography of gut symbiotic and aposymbiotic Nezara viridula L. (Hemiptera: Pentatomidae).
Nezara viridula L. is a highly polyphagous and cosmopolitan pentatomid stink bug. Despite its economic importance, aspects of its biology are poorly understood. N. viridula has one primary bacterium associated with its gastric caeca, which females provide to offspring by smearing it on the surface of eggs during oviposition. We studied the impact of three temperatures and egg mass surface steri...

Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 +/- 1 degrees C), RH (60 +/- 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean a...
متن کاملPotential use of antibiotic to improve performance of laboratory-reared Nezara viridula (L.) (Heteroptera: Pentatomidae).
The antibiotic streptomycin added to the drinking water at a concentration of 125 mg/ l during nymphal development of Nezara viridula (L.) (Heteroptera: Pentatomidae)accelerated the development in ca. 2 days, increased survivorship, and doubled adult longevity; nymph survivorship and adult body weight were not affected when compared to control insects. Streptomycin has potential in rearing N. v...
متن کاملEvidence of stochastic resonance in the mating behavior of Nezara viridula (L.)
We investigate the role of the noise in the mating behavior between individuals of Nezara viridula (L.), by analyzing the temporal and spectral features of the non-pulsed type female calling song emitted by single individuals. We have measured the threshold level for the signal detection, by performing experiments with the calling signal at different intensities and analyzing the insect respons...
