In Egypt, only five species of Dermaptera (earwigs) have been reported. Based on both the morphological and molecular data of the earwig samples collected from a bakery in Beni-Suef, Egypt, we identified the species as (Spongiphoridae), a cosmopolitan species with no prior records in Egypt. The current study was designed to analyze its predation capability on newly emerged eggs and larvae of the tick. A laboratory functional response study was set up by applying a predation test with various predator-prey ratios as treatments. This experiment was applied using the undefined mix of collected earwigs and the laboratory-collected eggs and the larvae of . The laboratory results showed that the mean number of predated tick eggs was 18.64 ± 11.18 in 24 h under the highest predator-prey ratio (1:10) examined, accompanied by 12.04 ± 4.38 broken but unconsumed eggs. Moreover, predated an average of 12.32 ± 9.07 tick larvae per day. In contrast, the mean dead larvae increased to 38.4 ± 2.30 per day with the highest predator density (1:10). The number of eggs and larvae consumed increased with the predator density. A linear relationship was detected between earwig density and the consumption rates of tick eggs (R = 0.99; = 0.0001) and larvae (R = 0.96; = 0.003). In conclusion, was first recorded in Egypt. This earwig has predation capability on tick eggs and larvae.
在埃及，仅报道过5种革翅目昆虫（蠼螋）。基于从埃及贝尼苏韦夫一家面包店采集的蠼螋样本的形态学和分子数据，我们将该物种鉴定为（海绵蠼螋科），这是一种世界性分布的物种，此前在埃及没有记录。本研究旨在分析其对新孵化的蜱虫卵和幼虫的捕食能力。通过应用不同捕食者与猎物比例作为处理的捕食试验，建立了一项实验室功能反应研究。该实验使用采集的蠼螋与实验室采集的蜱虫卵和幼虫的未定义混合物进行。实验室结果表明，在最高捕食者与猎物比例（1:10）下，24小时内平均被捕食的蜱虫卵数量为18.64±11.18，同时有12.04±4.38个破损但未被消耗的卵。此外，蠼螋平均每天捕食12.32±9.07只蜱虫幼虫。相比之下，在最高捕食者密度（1:10）下，平均每天死亡的幼虫数量增加到38.4±2.30。被捕食的卵和幼虫数量随捕食者密度增加。在蠼螋密度与蜱虫卵（R = 0.99；P = 0.0001）和幼虫（R = 0.96；P = 0.003）的消耗率之间检测到线性关系。总之，该蠼螋在埃及首次被记录。这种蠼螋对蜱虫卵和幼虫具有捕食能力。
