Spodoptera frugiperda has co-occurred with Spodoptera litura in corn fields since it invaded China on December 2018. In our process of rearing S. frugiperda and S. litura larvae in the lab, we discovered that when the larvae of S. litura and S. frugiperda were on the same host plant, two-way predation between them occurred. However, a detailed study on this phenomenon has not been previously reported. Therefore, the study on the two-way predation between larvae of S. frugiperda and S. litura was performed under mimicking natural conditions including the presence or absence of maize leaves. The results showed that 4th instar larvae of S. frugiperda could prey actively on the 3rd instar larvae of S. litura under natural conditions in the greenhouse, and there was twoway predation between S. frugiperda and S. litura larvae in either the presence or absence of maize leaves in the lab. In addition, the difference in the daily predation number of old S. frugiperda larvae (including 4th,5th and 6th instar) on S. litura 1st, 2nd and 3rd instar larvae respectively was significant between presence and absence of maize leaves. Similarly, the difference in the daily predation number of S. litura old larvae (including 4th, 5th and 6th instar) on S. frugiperda young 1st, 2nd and 3rd instar larvae respectively was very significant between presence and absence of maize leaves. These results confirm that two-way predation exists between larvae of S. frugiperda and S. litura, and S.frugiperda larvae are in a dominant position in this struggle, which provides an understanding of S. frugiperda feeding when coexisting with S. litura.

Objective: To introduce a technique of laminotomy using a common trephine to enlarge the interlaminar space at L4/5 segment for interlaminar endoscopic lumbar discectomy (IELD) and report the anatomical basis of this procedure, technical details, as well as primary clinical outcomes of a consecutive patient cohort with L4/5 lumbar disc herniation (LDH). Methods: On anteroposterior fluoroscopy, the intersection of the medial edge of the inferior articular process and the inferior endplate of L4 vertebra was taken as the target. Using a common trephine, laminotomy was performed to remove a big portion of the posterior wall of the canal under the guidance of endoscopy. From June 2018 to December 2021, the consecutive patients who underwent L4/5 IELD were prospectively studied. Clinical outcomes were assessed at the day before surgery, 1 day, 1 month, 3 months, 12 months after surgery, and the last follow-up. Numerical Rating Scale, Roland-Morris Disability Questionnaire (RMDQ), and MacNab criteria were used to evaluate back and leg pain, the quality of life, and clinical efficacy, respectively. Results: There were 64 men and 44 women, with an age of 50.3 ± 14.9 years. The operating time was 74.54 ± 17.42 minutes. The mean follow-up time was 32.7 ± 18.6 months (range, 12–64 months). The complications of IELD included numbness, neck pain, and recurrence. Both leg pain (6.2 ± 1.9 vs. 1.8 ± 0.8, p < 0.001) and back pain (3.1 ± 2.3 vs. 1.7 ± 0.9, p < 0.001) quickly improved after this procedure and maintained (1.1 ± 1.5, 1.1 ± 1.3) at final follow-up. Physical disability due to back pain, as assessed using RMDQ, was improved remarkably after surgery (15.0 ± 5.8 vs. 2.9 ± 4.1, p < 0.001). In addition, MacNab outcome grade was evaluated as good-to-excellent in 96 cases (88.9%). Conclusion: A convenient technique of laminotomy using a common trephine was proposed for the L4/5 IELD. It can efficiently enlarge the interlaminar entry to perform endoscopic discectomy. This procedure is particularly suitable for treating LDH with concomitant lumbar spinal stenosis and migrated herniated disc.
