Redescription of Pterygodermatites (Mesopectines) nycticebi (Mönnig, 1920) (Nematoda: Rictulariidae), a parasite of slow loris Nycticebus coucang (Mammalia: Primates)

Pterygodermaties (Mesopectines) nycticebi (M?nnig, 1920) (Nematoda: Spirurida: Rictulariidae) is redescribed based on immature and mature adults collected from the stomach and small intestine at autopsy of a slow loris, Nycticebus coucang (Boddaert, 1785) (Mammalia: Primates), in a zoological garden in Japan. It is first demonstrated that male possesses a minute telamon and a left lateral pore in the preanal part of body. The cause of death of the slow loris is strongly surmised to be related to the nematode infection, which was apparently acquired under captivity in the zoological garden.

Assessment of resistance risk in Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) to chlorantraniliprole

BACKGROUND: Beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is a major pest of numerous cultivated crops. Chlorantraniliprole, the first commercialised ryanodine receptor insecticide from the anthranilic diamide class, has exceptional insecticidal activity on a range of lepidopteran pests. The aim of this study was to assess the resistance of S. exigua to chlorantraniliprole in the laboratory. RESULTS: A field‐collected population of S. exigua was selected after repeated exposure to chlorantraniliprole to determine the risk of resistance evolution. After 22 generations of selection, there was a 12.0‐fold increase in LC₅₀. The realised heritability (h²) of resistance was estimated as 0.1082 by using threshold trait analysis. The projected rate of resistance evolution indicated that, if h² = 0.1082 and 70% of the population was killed at each generation, then a tenfold increase in LC₅₀ would be expected in 21.7 generations for chlorantraniliprole. CONCLUSION: These results show that the risk of resistance development to chlorantraniliprole exists in S. exigua after continuous application. Copyright © 2011 Society of Chemical Industry     

中国的钝绥螨属记述(Phytoseiidae:Amblyseins)

钝绥螨属Amblyseius Berlese是植绥螨科(Phytoseiidae)中种类最多的一个属,是为害农作物螨类(叶螨、细须螨、跗线螨、瘿螨)的重要天敌类群。我国有关植绥螨的分类研究材料不多,到目前为止共收集的种类和已见有关报导的有五十多种,其中以钝绥螨属为主。本文记述钝绥螨属在我国分布的重要种,对目前正在利用的和自然保护中的重要种作了较详细的描述。种上有“*”号的为我国分布首次记录,有“**”号的为我国已有分布记录,但作者仍未见标本的,在这里一并列入,以供参考。     

Effectiveness of two insect growth regulators against Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) and Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) and their impact on population densities of arthropod predators in cotton in Pakistan

Field efficacies of two insect growth regulators (IGRs) at two recommended application rates, buprofezin at 370 and 555 g AI ha(-1) and lufenuron at 37 and 49 g AI ha(-1), were determined against the sweet potato whitefly, Bemisia tabaci (Gennadius), and the cotton bollworm, Helicoverpa armigera (Hübner), in experimental plots of cotton at the Directorate of Cotton Research, Faisalabad, Pakistan. Adverse effects of the IGRs on populations of associated arthropod predators, namely geocorids, chrysopids, coccinellids, formicids and arachnids, were also assessed. Both IGRs significantly reduced populations of B. tabaci at each application rate 24, 48 and 72 h after treatment, and higher doses were more effective than lower doses. Buprofezin was not effective against H. armigera at any tested dose for any time of treatment in any spray. Lufenuron applied at 37 and 49 g AI ha(-1) effectively suppressed H. armigera populations, resulting in significant reductions in crop damage. At lower doses, both IGRs appeared safe to predator populations, which did not differ significantly in IGR-treated versus untreated control plots. Population densities of formicids and coccinellids were significantly lower at high concentrations of both IGRs in treatment plots, possibly as a result of reduced prey availability. The potential role of buprofezin and lufenuron for control of B. tabaci and H. armigera in a spray programme and the likelihood of direct toxic effects of IGRs on predatory fauna of cotton are discussed.     

豚草条纹叶(虫甲)(鞘翅目:叶(虫甲)科)的寄主专一性测定

1987年从苏联、加拿大引进原产北美的豚草天敌—豚草条纹叶(虫甲),在室内用具有代表性的23科72种主要经济作物、粮食作物、观赏植物及与豚草近缘或形态上相似的植物,进行了食性测定。结果表明,豚草条纹叶(虫甲)食性专一,仅取食豚草,不取食其它任何供试植物,在我国可以安全利用。在饥饿条件下,一龄幼虫的耐饥能力为3.1天,雌、雄成虫的耐饥能力分别为14和10.2天。

The effect of piperonyl butoxide on pyrethroid-resistance-associated esterases in Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)

Pyrethroid resistance in field populations of Australian Helicoverpa armigera (Hübner) is primarily a consequence of the overproduction of esterase isoenzymes which metabolise and sequester pyrethroid insecticides. Biochemical studies have shown that pyrethroid-resistance-associated esterases in H armigera are inhibited by the insecticide synergist piperonyl butoxide (PBO). Esterase inhibition by PBO did not occur immediately after dosing, but exhibited maximum inhibition 3-4 h after dosage. Esterase activity subsequently recovered until full activity was restored by 24 h. Topical bioassays using a pre-treatment of PBO showed that maximum H armigera mortality was achieved with pre-treatment times corresponding to maximum esterase inhibition. These results demonstrated that, with correct temporal application, PBO can restore pyrethroid efficacy against H armigera. It would also be expected that restoration of efficacy with other conventional insecticides, currently compromised by esterase-based resistance mechanisms, would occur.     

Emergence de Ceratitis capitata (Diptera: Tephritidae) sur culture protégée de piment (Solanaceae) en zone subsaharienne (Algérie)

In Algeria, the Mediterranean fruit fly has long been associated with fruit production in coastal regions with a temperate climate. But with climate change, especially in autumn and spring, this fly has spread and attacks other host plants. The medfly appeared in the sub-Saharan area of Souf region (Algeria) on chilli pepper (Capsicum annuum) under protected crops and causes significant damage.     

番茄褪绿病毒(tomato chlorosis virus)的新寄主:水茄(Solanum torvum Swartz)

Tomato chlorosis virus (ToCV) is a plant virus that is mainly propagated by Bemisia tabaci in a semi-persistent and non-circulative manner.It has a wide range of host plants,and has been reported in many countries,causing serious economic losses in vegetable production.In 2019,we investigated about 10 fields,one ha each in Shouguang,Shandong province (China),and in each field we observed symptoms of interveinal chlorosis on lower leaves of the Solanum torvum Swartz,and a large number of B.tabaci gathered on the back of its leaves.To determine the presence of ToCV,total RNA of S.torvum was extracted followed by RT-PCR.The 1 074 (GenBank accessions number MN545620) and 466 bp (GenBank accessions number MN545621) fragments were gel purified and sequenced.The sequences shared 99.44% and 99.57% similarity with ToCV reference sequence tomato chlorosis virus segment RNA1 (AY903447) and RNA2 (AY903448).The results of insect transmission test confirmed that ToCV can spread from S. torvum to tomato.This study confirms S.torvum as a newly reported host of ToCV.
