“…The in uence of temperature and host plants on the basic biology of M. sacchari was early made in Japan (Setokuchi, 1973;1974;1975). These papers coincide with method and results of the present study at the next points: Period of rearing and bioassays (June to October), use of sorghum leaves and treatments temperatures of 15, 20, 25 and 30°C).…”

The Sugarcane aphid, Melanaphis sacchari (Zehntner, 1897) is the most important pest in sorghum crops of USA and Mexico. In northern Mexico and other regions, as Guanajuato and Morelos, reduced over 30% of the cultivated area of sorghum between 2016 and 2019. This study provides basic information that supports the Integrated Management of this insect. Research used biological material (parthenogenetic forms) from Guanajuato, Mexico; reared in foliar agar-disc of Sorghum bicolor VAR. UPM-219, at bioclimatic chamber under different temperatures: 5, 10, 15, 20, 25, 30, 35 and 40°C. The highest mortalities occurred in extremes temperatures: 5°C (35%), 35°C (45%) and 40°C (100%). At low temperature (5°C) there was no reproduction and the pre-reproductive period continued 62.5 days, allowing the insects to survive on average 88.2 days. At the highest temperature (40°C), nymph 1 died in 0.9 days. While at 20°C, M. sacchari produced a supernumerary N5 stage that prolonged the development to 7.1 days. The longest reproductive period was 33.2 days (0.6 nymphs/day) to 10°C, in contrast to 4.1 days (0.4 nymphs/day) to 35°C; the longest post-reproductive period (22.4 days) was obtained at 10°C and the smallest (4.2 days) at 35°C. Highest average fertility (79.06 nymphs) was reached at 25°C. Theoretical thermal thresholds was 2.0° and 40°C; and the heat units t required for each generation were 158.9. Population parameters show that 25°C is the optimal temperature for this aphid Ro (79.06) and Rm (0.44) T (10.01) DT (1.59 and λ (1.55).

“…The sugarcane aphid, M. sacchari (Homoptera: Aphididae), is considered an economically important pest to sorghum in China (Wang, 1961), Taiwan (Chang, 1981a,b;Pi and Hsieh, 1982a), Japan (Setokuchi, 1973), India (Young, 1970), South Africa (van Rensburg, 1973a, and Botswana, while it is common to cultivated sorghum in Zimbabwe (Flattery, 1982). Sorghum responses to M. sacchari injury include purple leaf discoloration of seedlings, followed by chlorosis, necrosis, stunting, delay in flowering, and poor grain fill, including quality and quantity yield losses.…”

The sorghum [Sorghum bicolor (L.) Moench] germplasm lines RTx3410 through RTx3428 (Reg. No. GP-846 to GP-864, PI 686993 to PI 687011) were developed and released by Texas A&M AgriLife Research, Lubbock, TX, in 2018. The lines are resistant to damage caused by the sugarcane aphid [Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae)] (SCA). All lines were developed by intentional plastic bag emasculation crosses and selected using the pedigree method of plant breeding. Resistance in RTx3410 through RTx3426 was identiied after the SCA became a consistent pest of sorghum in the United States in 2013. To develop RTx3427 and RTx3428, crosses and selections were made in the Texas A&M AgriLife Research program at various Texas locations and resistance to the SCA in southern Africa was identiied in Botswana and South Africa. Resistance in the United States was conirmed following identiication of virulent SCA in 2013. All lines at seedling and adult plant stages expressed moderate to high levels of resistance to SCA. Resistance in RTx3412 to RTx3426 is derived either from Tx2783 or an early generation sib. Resistance in RTx3410, RTx3411, RTx3427, and RTx3248 is from unknown sources of resistance. The genetic relationship between the resistance gene(s) from the diferent sources is not known. The lines with potentially diverse sources of resistance provide the sorghum industry with a diversity of elite germplasm with resistance to SCA.
