ABSTRACT: In order to study fauna of Cryptinae, Pimplinae and Tryphoninae (Hymenoptera: Ichneumonidae), three Natural Protection Areas (Halep Çamlığı, Kengerlidüz, and Habib-i Neccar) were chosen sampled by various techniques from East Mediterranean Region of Turkey between 2007-2008. The same localities were again sampled between 2014-2015 and added. A total of 112 samples were collected and 38 species determined. Eleven species are new records for Turkey. Centers of diversity are given for each species.

The crabronid wasp genus Sphecius contains 21 described species (Pulawski, 2020). Of these, five are recorded in the New World (Bohart, 2000): Sphecius convallis Patton, 1879; S. grandis (Say, 1823); S. hogardii (Latreille, 1809); S. speciosus (Drury, 1773) and S. spectabilis (Tashenberg, 1875). In Mexico, only three species have been registered: S. convallis, S. grandis and S. speciosus (Holliday & Coelho, 2006; Coelho et al., 2011). Sphecius convallis is distributed in eleven states of Mexico (Fig. 1A): Baja California (Krombein, 1979; Ruíz et al., 2002; Coelho et al., 2011; Pulawski, 2020), Baja California Sur (Coelho et al., 2011; Pulawski, 2020), Chihuahua, Coahuila, Jalisco, Morelos, Querétaro, San Luis Potosí, Sinaloa, Sonora (Coelho et al., 2011) and Tamaulipas (Horta et al., 2007; Coelho et al., 2011). In this work, we record the first record of S. convallis from the state of Oaxaca (Fig. 1A). It was identified using keys of Holliday & Coelho (2006).
crabronid黄蜂属Sphecius包含21个描述的物种（Pulawski，2020）。其中有五个记录在《新世界》（Bohart，2000）中：Sphecius convallis Patton，1879年；S.grandis（Say，1823）；S.hogardii（Latreille，1809）；S.specious（Drury，1773）和S.spectabilis（Tasenberg，1875）。在墨西哥，只有三个物种被登记：康瓦利斯S.convallis、格兰迪斯S.grandis和特种S.specious（Holliday&Coelho，2006；Coelho等人，2011年）。锥状Sphecius convallis分布在墨西哥的11个州（图1A）：下加利福尼亚州（Krombein，1979年；Ruíz等人，2002年；Coelho等人，2011年；Pulawski，2020）、南加利福尼亚州（Coelho et al.，2011；Pulawski2020）、奇瓦瓦州、科阿韦拉州、哈利斯科州、莫雷洛斯州、克雷塔罗州、圣路易斯波托西州、锡那罗亚州、索诺拉州（Coalho等人，2012年）和塔毛利帕斯州（Horta等人，2007年；Coerho等人，2010年）。在这项工作中，我们记录了瓦哈卡州的第一个对流S.convallis记录（图1A）。它是使用Holliday&Coelho（2006）的密钥识别的。

ABSTRACT: The long green planthopper Saccharosydne procerus is one of the serious pests of water-oat Zizania latifolia. Characterization of its antennal sensilla is vital for developing practical monitoring and management strategies of this pest. In the present study, the antennae of S. procerus (with particular focus on the sensilla) are illustrated using scanning electron microscopy. The results show that the antennae of both sexes are similar. The flagellum consists of an apical segmented arista and a basal bulb. Four types of sensilla were identified: campaniform sensilla, trichoid sensilla, chaetic sensilla and plaque organs. The campaniform sensilla are found on the distal rim of the scape. The trichoid sensilla I are sparsely distributed on the scape, and the trichoid sensilla II are densely distributed on the 3/4 distal area of the pedicel. The chaetic sensilla are sparsely distributed on the outer margin of the scape and pedicel. Abundant plaque organs are exclusively distributed at the distal area of the pedicel. The morphology and distribution of sensilla are compared and their possible functions are discussed.

ABSTRACT: We studied the pollination biology of a native orchid Spiranthes australis in Kobe, Hyogo, Japan, and observed that S. australis flowers are frequently visited by the managed honeybee A. mellifera. Since the honeybees extracted pollinaria from the anthers and deposited pollinia on the stigmas of many flowers, the behavior resulted in the successful pollination of multiple flowers even in a single visitation. Given that (i) the honeybee was the most frequent and intensive pollinator during our observation period and (ii) the fruit set in the investigated population was significantly higher than the fruit set of a previously investigated S. australis population, despite lack of ability for autonomous self-pollination, A. mellifera may promote a high reproductive success in S. australis. Our observation provides some insight into the diversity of orchid-pollinator interactions, drawing attention to the potential importance of non-native bees as pollinators.

ABSTRACT: Aphid species, their parasitoids and predators on Curled dock (Rumex crispus L.) naturally grown in Erzincan and Erzurum provinces, Turkey were determined. Surveys were conducted at two week intervals from the seedling period until the end of the harvest period in 2017 and 2018. In the surveys, 30-40 plants were randomly selected and all parts of these plants were investigated with a magnifier. Four aphid species, thirteen predator and two parasitoid species were found. Rumex crispus was recorded for the first time as a host of Acyrthosiphon rubi Narzikulov (Hemiptera: Aphididae). In addition, parasitism rates of aphids were also established. The mean parasitism rate changed between 23.2% in 2017 and 23% in 2018. The relationship between total aphid number, total parasitized (mummified) aphid number and parasitism rate was measured. There was a high positive correlation (r = 0.838-0.861) between total aphid number and total parasitized aphid number, and a weak or intermediate correlation (r = 0.180-0.412) between total aphid number and parasitism rate during both growing seasons.

ABSTRACT: The holotype of Delphacodes guianensis Muir, a delphacid planthopper (Hemiptera: Fulgoroidea: Delphacidae) currently nominally in the polyphyletic genus Delphacodes Fieber, was examined and found to bear lateral teeth on the hind basitarsus, a synapomorphy of the genus Nilaparvata Distant. We determined that Delphacodes guianensis is a senior synonym of Nilaparvata serrata Caldwell. Here we move this species into Nilaparvata to provide the new combination Nilaparvata guianensis (Muir) and give Nilaparvata serrata as a new junior synonym.

ABSTRACT: A laboratory experiment was conducted on two potential reproductive host plant species of the whitefly Bemisia tabaci (Gennadius). The two plant species, Brassica carinata A. Braun (carinata or Ethiopian mustard) and Myrica cerifera L. (southern wax myrtle), were considered for study as potential overwintering host species for B. tabaci because of their presence with green foliage in the southeastern United States agricultural community from the fall through spring season. The Middle-East-Asia Minor 1 of the cryptic whitefly species group of B. tabaci survives the mild winters in the southeastern United States. In this study, B. carinata was demonstrated to be a favorable host plant for B. tabaci. Based on a no-choice experiment, oviposition, egg hatch, and survival to the adult stage were similar for whiteflies on B. carinata as compared with collard (B. oleracea var. acephala de Condolle), a known favorable host for B. tabaci. However, results from a dual choice experiment indicated that the whiteflies preferred B. carinata to B. oleracea for feeding and oviposition. Conversely, although southern wax myrtle served as an ovipositional host, the ovipositional performance of B. tabaci in a no-choice assay was over eight-fold less than on B. carinata, and nymphal survival was not successful beyond the second instar on southern wax myrtle in a laboratory experiment. However, a few nymphs survived to the fourth instar on intact plants of southern wax myrtle in the landscape. The results of this study have implications on whitefly population dynamics. Winter populations of B. tabaci are suppressed in the field, but plant species, such as carinata or collard, that are present during the mild winter may help support a buildup of whiteflies during the spring.
摘要：对两种具有潜在繁殖潜力的烟粉虱寄主植物进行了室内试验。这两个植物物种，芸苔属（Brassica carinata A.Braun）（carinata或埃塞俄比亚芥末）和杨梅属（Myrica cerifera L.）（南蜡桃金娘），被认为是烟粉虱的潜在越冬寄主物种，因为它们在美国东南部的农业群落中从秋季到春季都有绿叶。在美国东南部的温和冬季，小东亚烟粉虱的一个隐蔽的粉虱种群存活下来。在本研究中，隆突B.carinata被证明是烟粉虱的有利寄主植物。根据一项无选择实验，与羽衣甘蓝（B.oleracea var.acephala de Condole）相比，白粉虫在隆鱼身上的产卵、孵化和成年期的存活率相似，羽衣甘蓝是已知的烟草的有利宿主。然而，双重选择实验的结果表明，在觅食和产卵方面，粉虱更喜欢隆突B.carinata而不是甘蓝B.oleracea。相反，尽管南方紫薇是产卵宿主，但在无选择试验中，烟粉虱的产卵性能比隆虫低8倍多，在实验室试验中，若虫在南方紫薇2龄以上的存活率并不成功。然而，在景观中，少数若虫在完整的南方蜡金娘植物上存活到四龄。这项研究的结果对白蝇种群的动态具有启示意义。烟粉虱的冬季种群在野外受到抑制，但在温和的冬季出现的植物物种，如隆尾虫或羽衣粉虱，可能有助于支持春季粉虱的繁殖。
