The Effect of Spinosad on the Oak Lace Bug (Hemiptera: Tingidae)-A Preliminary Study Performed Under Laboratory Conditions.

The effect of biopesticide compound spinosad in different concentrations was tested for the first time under laboratory conditions against the rapidly spreading forest pest, oak lace bug (, Say 1832), and its effects were compared with the synthetic pesticide lambda-cyhalothrin. These results revealed a significant effect of spinosad at 2 mL/4 L and 2 mL/2 L water concentrations against nymphs. The mortality rate after 3 days was similar to synthetic insecticide effects and reached 94% and 98%, respectively.

Endosymbiotic Bacterial Diversity of Corn Leaf Aphid, Fitch (Hemiptera: Aphididae) Associated with Maize Management Systems.

In this study, different maize fields cultivated under different management systems were sampled to test corn leaf aphid, , populations in terms of total and endosymbiotic bacterial diversity. Corn leaf aphid natural populations were collected from traditionally managed maize fields grown under high agricultural and natural landscape diversity as well as conventionally treated high-input agricultural fields grown in monoculture and with fertilizers use, hence with low natural landscape diversity. Total bacterial community assessment by DNA sequencing was performed using the Illumina MiSeq platform.
