Biodiversity and seasonality of Pyraloidea (Lepidoptera) in the woody savannah belt in Mali
Full text linkSeventy-nine species of Pyraloidea moths were collected from light traps in the vicinity of Bamako in Mali during 2014. Thirty-one species—for which over 10 specimens each had been trapped—were chosen for analysis of their seasonal dynamics. According to the similarity in their patterns of seasonal flight, three clusters were recognized by non-metric MDS ordination: (1) The beginning of the rain season was associated with a peak in several multivoltine, widespread, and highly abundant species, thus reducing to a minimum both the effective number of species index and index of evenness. In the middle of the rain season, the number of both species and specimens was low, probably reflecting the period of larval development for most of the species; (2) The first half of the wet–dry (transitional) season featured the highest diversity and highest evenness in the representation of species. More than half of 31 species are univoltine in the study region, and thus were found only during this period. All the species are Afrotropical or Paleotropical in their general distribution; (3) A group of 10 species peaked during the dry season. Five of these also occurred earlier, while the other five were specific to the dry season: A. simplella, B. asialis, P. phoenicealis, A. calligrammalis, and P. pictalis.

Potential of entomopathogenic fungus Isaria javanica for controlling the potato tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)
Full text linkThe potato tuberworm Phthorimaea operculella is an important cosmopolitan quarantine pest of the Solanaceae crops. Comparing the relative virulence of five entomopathogenic fungi against P. operculella, the results showed that Isaria javanica was more effective against eggs, larvae and pupae compared to the other tested isolates. Mean infection rates of ca 80% were obtained for individuals at different life stages treated with 1×108 conidia/mL. Based on the linear regression analyses of the mortality data, a median lethal concentration <1×106 conidia/mL was calculated for eggs, larvae and pupae, suggesting that this isolate of I. javanica may be a useful biocontrol agent for P. operculella. Variation was observed in the growth rates and sporulation of I. javanica on different culture media and at different temperatures. When cultured on peptone maltose agar, the fungus grew quickly, but sporulation rates were higher on corn meal agar and potato dextrose agar, producing 8.16×103 and 7.39×103 conidia/cm2, respectively. When cultured at different temperatures, the fungus grew faster at 27°C, and produced more conidia when grown at temperatures under 30°C. Our results indicate that I. javanica is a promising biocontrol agent for the potato tuberworm.
摘要
马铃薯块茎蛾 Phthorimaea operculella 是茄科作物上重要的世界性检疫害虫。本文通过比较五种不同昆虫病原真菌对马铃薯块茎蛾的相对毒力，发现与其它测试菌株相比，爪哇棒束孢 (Isaria javanica) 对马铃薯块茎蛾的卵、幼虫和蛹的作用效果更为明显，用浓度为1×108 孢子/mL的孢子悬浮液处理各虫态，平均死亡率约80%。通过线性回归分析所得爪哇棒束孢对卵、幼虫和蛹的平均致死中浓度（LC50）均小于1×106 孢子/mL，表明爪哇棒束孢对马铃薯块茎蛾有较好的生防效果。该生防真菌在不同培养基上和不同温度条件下的生长速率和产孢能力具有一定的差异。在蛋白胨麦芽糖琼脂（SMA）培养基上，其生长速率最快，但在玉米粉琼脂（CMA）培养基和马铃薯葡萄糖琼脂（PDA）培养基上，其产孢量最大，分别为 8.16×103孢子/cm2 和7.39×103 孢子/cm2。在27 oC培养条件下，其生长速率最快，但在30 oC 培养条件下，其产孢量最大。以上研究结果表明，爪哇棒束孢是具有广阔应用前景的生防因子，可用于马铃薯块茎蛾的生物防治。

Description of Raveniola ambardzumyani n. sp. from Armenia (Araneae: Nemesiidae)
Full text linkA diagnosis and illustrated description of Raveniola ambardzumyani n. sp. (♀) from Armenia is provided. The new species belongs to the Raveniola niedermeyeri species group, where it appears to be most closely related to R. niedermeyeri (Brignoli, 1972) itself. Raveniola ambardzumyani n. sp. differs from the latter species in the shape of receptacular branches arising from a narrow common base. The study briefly discusses the relationships and some peculiar characters (including the reduction of the posterior eyes, a triangular apical segment of the posterior lateral spinnerets, and a very specific configuration of the divided three-head spermathecae) of the new species.

Distribution patterns of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) eggs, nymphs and adults in a Malaysian citrus orchard
Full text linkSpatial distribution of eggs, nymphs and adults of Diaphorina citri (Hemiptera: Psyllidae) was studied in a commercial orchard in SW Sarawak, Malaysia, using mean–variance test, the index of dispersion, and the negative binomial distribution. To further ascertain and confirm the distribution pattern in the population of the psyllid, dispersion indices (index of mean crowding, Lloyd’s index of patchiness, Taylor’s power law and Iwao’s patchiness regression) were calculated. Measurable tests showed that distribution of eggs and nymphs in naturally occurring psyllid populations was highly aggregated, resulting from initially aggregated migration of adults and a contagious dispersion of them on flushes as the population density increased.

Addendum to the Israeli Noctuoidea fauna (Lepidoptera: Noctuidae, Erebidae)
Full text linkSeventeen species of Noctuoidea (Lepidoptera) are newly recorded for Israel, bringing the owlet moth fauna to 565 species. Four species are new records for the Levant, others have been known from Lebanon, Cyprus, Syria, and Jordan. Most of new records are done in the northern and southern parts of the country. The ‘southern’ group is represented by the Afrotropical and Pan-Eremic species, which reached the northern limit of their distribution. The ‘northern’ group is represented by species on the southern border of their distribution, including Trans-Palearctic and Mediterranean elements at the forested medium elevations, the Mediterranean–Iranian species in the montane steppes, and the alpine and xeromontane species at elevations over 2000 m. The pattern of occurrence of the new records reflects the position of Israel in the region as a transitional area between a more humid Mediterranean part in the north and a more arid part in the south.

Review of the Palearctic Aphelinoidea (Hymenoptera: Trichogrammatidae), with focus on the species described by Ś. Nowicki
Full text linkType specimens of Aphelinoidea anatolica Nowicki, A. anatolica melanosoma Nowicki (now A. melanosoma), A. deserticola Nowicki, and A. subexserta Nowicki (Hymenoptera: Trichogrammatidae), which were not examined by taxonomists since their original descriptions had been published, are identified, labeled, re-diagnosed, and illustrated. A lectotype is designated for A. anatolica. Taxonomic notes on these Palearcic taxa and also some other species of Aphelinoidea Girault in the Holarctic Region are provided along with a key to females of the Palearctic species. The subgenus Aphelinoidea (Diaclava) (Blood & Kryger), n. syn., is synonymized under the nominate subgenus, A. (Aphelinoidea) Girault, and its type species Diaclava waterhousei Blood & Kryger is transferred to the latter as A. (Aphelinoidea) waterhousei (Blood & Kryger), rev. stat. Aphelinoidea (Krygeriola) dolichoptera Nowicki, n. syn., and A. gwaliorensis Yousuf & Shafee, n. syn., are synonymized under A. (Lathromeroides) neomexicana (Girault), and A. retiruga Lin, n. syn., is synonymized under A. (Aphelinoidea) longiclavata Yousuf & Shafee. A new taxon, A. (Aphelinoidea) gerlingi n. sp., is described; it is known from specimens collected in Algeria, Egypt, Israel, Morocco, and Oman, and also, including the holotype, from vouchers of the colonies introduced (misidentified as A. anatolica) from Iran into California, USA, for biological control against the beet leafhopper, Neoaliturus (Circulifer) tenellus (Baker) (Hemiptera: Cicadellidae). To prevent further damage, most of the examined specimens in the Ś. Nowicki collection of Aphelinoidea at its current depository, the Entomological Collection of Dipartimento di Entomologia e Zoologia Agraria «Filippo Silvestri», Università degli Studi di Napoli «Federico II», Portici, Italy, were remounted into Canada balsam from the dried and often darkened original water-soluble mountant.

The incidence of Bemisia tabaci (Homoptera: Aleyrodidae) and its parasitoids on cassava and associated plants in Uganda
Full text linkBiotic and abiotic factors can influence the population dynamics of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae), a key pest of cassava and a vector of several viral diseases, and that of its parasitoids. To gain a better understanding of possible roles these factors, different crops/cropping systems and weeds play in determining B. tabaci population dynamics, cassava fields were surveyed monthly from November 2003 to December 2004 in Buliisa (Buliisa district), Busukuma (Wakiso district) and Lyantonde (Lyantonde district), Uganda. Bemisia tabaci and its parasitoids were more abundant on cassava than on both intercrops and weeds. Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae) was the most abundant parasitoid species followed by Encarsia sophia Girault & Dodd (Hymenoptera: Aphelinidae). An undescribed Encarsia sp. was relatively rare. The level of parasitism on cassava was highest at Busukuma (41.7%), followed by Buliisa (37.2%) and Lyantonde (32.2%). The only companion crop that harboured B. tabaci nymphs was sweet potato with 22 nymphs from 20 plants and 68% parasitism. Similarly very low numbers of nymphs were observed on the following weeds: Commelina benghalensis (4 parasitized nymphs from 1340 plants), Melhania sp. (over 76 nymphs from 60 plants with about 60% parasitism), Bidens pilosa (2 parasitized nymphs from 1080 plants) and Euphorbia sp. (8 nymphs from 580 plants with 75% parasitism). This demonstrates that cassava companion crops and weeds in the surveyed locations are not major hosts of B. tabaci. For these two reasons, cassava is the only significant source of cassava-colonizing B. tabaci. Whitefly and disease control on cassava should therefore focus on an integrated management strategy, including breeding for resistance to both constraints, and enhancing natural enemies, in a manner that addresses specific agro-ecosystems.

Adorning the dead or hiding the ration? The ant Plagiolepis pallescens Forel (Hymenoptera: Formicidae) constructs walls around food items
Full text linkThe ant Plagiolepis pallescens Forel, 1889 (Hymenoptera: Formicidae), common to the Middle East (Martinez & Amar 2014; Pashaei Rad et al. 2018), was found to build walls around food items that they were not hoarding, suggesting a concealment behavior. The ants were first discovered to build relatively massive structures under a garden tree, Triadica sebifera, in Givat Ada, Israel, by piling flowers around dead cockroaches. An experiment with eight different colonies of the ant species found that construction materials were not limited to flowers. It is hypothesized that structures built by the ants around food items provide visual and olfactory concealment.
