Aphis Glycines

Penelitian ini bertujuan untuk mempelajari dan mendapatkan informasi mengenai aspek biologi dan statistik demografi Aphis glycines pada tanaman kedelai. Penelitian dilaksanakan di Laboratorium Hama dan Rumah Kawat, Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya, Malang pada bulan November 2019 sampai Maret 2020. Pengamatan biologi meliputi siklus hidup, lama hidup, dan keperidian A. glycines, digunakan dalam perhitungan data demografi. Parameter demografi meliputi laju reproduksi kotor (GRR), laju reproduksi bersih (R0), laju pertambahan instrinsik (rm), dan masa generasi (T). Hasil penelitian menunjukkan bahwa A. glycines mempunyai tahap perkembangan meliputi fase nimfa instar I sampai instar IV dengan rataan perkembangan berturut-turut berlangsung selama 1,000; 1,118; 1,068; 1,091 hari. Rataan siklus hidup A. glycines terjadi selama 4,352 hari dengan keperidian 50,363 individu/imago betina. Sedangkan rataan lama hidup A. glycines yaitu 12,843 hari. Nilai statistik demografi A. glycines pada tanaman kedelai diperoleh antara lain nilai GRR sebanyak 50,373 individu/generasi, nilai R0 sebanyak 35,681 individu/ induk/generasi, nilai rm sebanyak 0,285 individu/induk/hari, dan nilai T yaitu 12,557 hari.

Abstract Soybean aphid (Aphis glycines Matsumura (Hemiptera: Aphididae)) has been a major pest of soybean in North America since its detection in this continent in 2000 and subsequent spread. Although several aphid resistance genes have been identified, at least four soybean aphid biotypes have been discovered, with three of them being virulent on soybean cultivars with certain soybean aphid resistance genes. These biotypes are known to vary across years and locations, but information on their variation within single fields is limited. An investigation was conducted to study the variation of soybean aphid biotypes within single townships and fields in Minnesota. Screening of 28 soybean aphid isolates collected from seven soybean fields (six soybean fields in Cairo and Wellington Townships of Renville County, MN and one field in Wilmar Township of Kandiyohi County, MN) revealed the existence of multiple known biotypes of soybean aphid within single fields of soybean. We found up to three biotypes of soybean aphid in a single field. Two biotypes were found in five fields while only one field had only a single biotype. Three isolates presented reactions on a panel of resistant and susceptible indicator lines that were different from known biotypes. These results highlight the importance of characterizing soybean aphid biotypes in small geographical areas and utilizing generated knowledge to develop soybean cultivars pyramided with multiple resistance genes. The outcome will be decreased use of insecticides, thereby improving economic and environmental sustainability of soybean production.

The soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae) is a primary pest of soybeans and poses a serious threat to soybean production. Our studies were conducted to understand the effects of different concentrations of insecticides (imidacloprid and thiamethoxam) on A. glycines and provided critical information for its effective management. Here, we found that the mean generation time and adult and total pre-nymphiposition periods of the LC50 imidacloprid- and thiamethoxam-treatment groups were significantly longer than those of the control group, although the adult pre-nymphiposition period in LC30 imidacloprid and thiamethoxam treatment groups was significantly shorter than that of the control group. Additionally, the mean fecundity per female adult, net reproductive rate, intrinsic rate of increase, and finite rate of increase of the LC30 imidacloprid-treatment group were significantly lower than those of the control group and higher than those of the LC50 imidacloprid-treatment group (P < 0.05). Moreover, both insecticides exerted stress effects on A. glycines, and specimens treated with the two insecticides at the LC50 showed a significant decrease in their growth rates relative to those treated with the insecticides at LC30. These results provide a reference for exploring the effects of imidacloprid and thiamethoxam on A. glycines population dynamics in the field and offer insight to agricultural producers on the potential of low-lethal concentrations of insecticides to stimulate insect reproduction during insecticide application.
