Abstract This study was carried out to identify the Tachinidae fauna in northern Iran during 2010-2011 and ten species belonging to nine genera and two tribes of the subfamily Dexiinae were found. The species Estheria petiolata, Periscepsia spathulata, Stomina caliendrata and Thelaira nigripes are new records for the Iranian tachinid fauna.

Abstract Brown pepper (Piper guineense) seed powder, used for culinary and medicinal purposes, was evaluated in the laboratory with a conventional storage chemical, actellic 2% dust (Pirimiphos-methyl), as standard, to protect stored cowpea against the cowpea bruchid, Callosobruchus maculatus. Four rates of the seed powder were used (2.5, 5.0 and 10.0 g/100 g seed with a control, 0.0 g) while actellic dust was applied at 1.0, 2.0, 3.0 g/100 g seed and 0.0 g/100 g seed as control. Data on percentage mortality, oviposition, adult emergence and seed damage were collected over a six-month period. Weevil perforation indexes (WPI) were estimated with the seed damage data. All data were analysed for variance at P≤0.05. Actellic dust at the lowest dose inflicted adult mortality (90 – 100%) in the first 48 h after treatment and prevented oviposition (95 – 100%) in the first five months of storage compared to the control. The highest rate of Piper guineense application caused mortality of up to 90.0% in 48 h, reduced oviposition (70 – 80%), decreased adult emergence (15.90 to 28.40 insects) as against the control (104.7 – 272.7 insects) and reduced seed damage by 80 % with a WPI of between 33.3 and 10.0 %. Proximate analysis and germination tests indicated that the treatment materials increased the moisture and crude fibre content, decreased crude protein content but had no significant effect on the viability of stored seeds. Organoleptic tests demonstrated that treatment materials had no significant negative effect on taste, odour, texture, appearance and overall acceptability of cooked cowpea seeds after six months of storage. It can be safely concluded that the powdered form of P. guineense seed at the highest doses (5.0 and 10.0 g) gave significant protection of cowpea seeds against the cowpea bruchid, which compared favourably with actellic dust when applied topically.

Abstract The efficacy of five insecticides containing a.i. bifenthrin, dimethoate, spinosad, spinetoram and chlorfenapyr was evaluated following RCBD against Thrips tabaci in farmer’s field for two consecutive years. The data were recorded before and after 24 h, 48 h, 72 h and 7 days of spraying. The results showed that all the insecticides reduced thrips populations compared to controls. However, the maximum reduction in thrips population and highest onion bulb yield (34.07 t/ha) was obtained with dimethoate 40EC followed by bifenthrin 10EC (33.14 t/ha). The minimum onion bulb yield (25.71 t/ha) was obtained in the control, where no insecticide was applied against thrips. If onion thrips are not controlled, the damage they cause can reduce bulb yields by 9-25%. The highest incremental return over the control (Rs.83, 600/ha), net income (Rs.82, 913/ha) and maximum cost benefit ratio were also obtained in the treatment with dimethoate 40EC.

Abstract Experiments were undertaken in connection with the need, indicated in the literature, for the proper choice of a substance enhancing the effect of a low oxygen atmosphere used as a means of controlling wood boring insects in museum collections and historical objects. A low oxygen atmosphere itself causes the death of wood boring insects after a relatively long period of application. Thus, attempts were made to use p-dichlorobenzene to accelerate the effects of a low oxygen atmosphere in the control of wood boring insects. The experiments were performed as a continuation of preliminary research on the effect of p-dichlorobenzene on Anobiidae in an aerobic atmosphere. The paper present the results of gassing Anobium punctatum and Ptilinus pectinicornis (Coleoptera: Anobiidae) larvae with 1,4-dichlorobenzene in a low oxygen atmosphere of nitrogen and argon. The experiments were performed in laboratory conditions at a temperature of 20°C on larvae extracted from wood. The results do not show a faster elimination of larvae of either species using p-dichlorobenzene in a low oxygen atmosphere as compared to using p-dichlorobenzene in an aerobic atmosphere. Complete eradication of larvae in the test groups was obtained after 48 hours when using p-dichlorobenzene in nitrogen. The results obtained when using p-dichlorobenzene in argon appear to be worse at fumigation times shorter than 48 hours.

Abstract Female swarming behaviour has rarely been described in Culicoides. Previous records of female swarms have only been described for females swarming in mixed swarms together with males. Two new observations of Culicoides swarms in Sweden are described here: a mixed swarm with females of Culicoides obsoletus / gornostaevae and males of C. gornostaevae, and a purely female swarm of C. impunctatus. Swarming behaviour can facilitate predator confusion. Swarming behaviour is therefore an evolutionary advantage that can explain mixed species swarms and purely female swarms.

Abstract Dirhinus giffardii is an efficient and aggressive pupal parasitoid of tephritid flies, including Bactrocera cucurbitae. Here we report on the various biological aspects of Dirhinus giffardii, mainly host-age preference, potential as well as the survival of this parasitoid from the pupae of different ages and its in vivo release against Bactrocera cucurbitae. The emergence rate of parasitoids was higher in old pupae than in fresh pupae. Similarly, the lifespan and potential of parasitoids emerged from older pupae were higher than those emerged from younger ones. The parasitoids reared on older pupae significantly controlled melon fly infestation in vivo. These findings suggest that parasitoids reared on older pupae of B. cucurbitae have a greater potential regarding fecundity, parasitism performance and survival, as these parasitoids effectively suppressed populations of B. cucurbitae under greenhouse conditions.

Abstract The new species Acrophylla bhaskarai sp. n. from Larat Island, Indonesia, is described from both sexes and the egg. It is the second species of the genus Acrophylla Gray, 1835 known from outside Australia and the first record of the genus from Wallacea. The discovery raises the number of genera of the tribe Phasmatini known to occur within the boundaries of Wallacea to five.

Abstract Parnopes grandior is a species that until recently was on the brink of extinction in Poland. Current data, however, indicates that it is expanding north-westwards. Most records of this species come from after the year 2000, primarily in northern Poland, especially in the north-eastern part of the country. Simultaneously, our research has shown that anthropogenic habitats like sand quarries and military training grounds are optimal sites for P. grandior.

Abstract The African variegated grasshopper, Zonocerus variegatus, exhibits daily variations in its feeding and destructive activities. A study to investigate circadian variation in metabolites (lipids, protein, glucose, K+, Ca2+, Mg2+, Cl−) concentrations and enzymes (lipase, amylase, proteinase, α-glucosidase) activities in the femoral and thoracic muscles of adult Z. variegatus was carried out by collecting samples at 06:00, 12:00, 18:00 and 24:00 hrs GMT. The four enzymes were present throughout the day in both thoracic and femoral muscles but at varying levels. Significantly (p<0.05) higher enzymes activities were measured during the day (between 06:00 and 18:00 hours GMT) (except proteinase) than at night (24:00 hrs). Organic substances in the two tissues were present in significantly higher concentrations during the day than at night. Similarly, significantly more inorganic substances were recorded in the afternoon (12:00-18:00 hrs) than at night in both femoral and thoracic muscles. It can thus be concluded that locomotor activities in Z. variegatus reach a peak during the day.

Abstract Stenopelmus rufinasus, a North American weevil introduced to Europe along with the invasive aquatic fern Azolla filiculoides, has been recorded from Poland for the first time. Its locality is a natural oxbow lake of the River Odra in Wrocław, the only city in Poland where A. filiculoides has been repeatedly recorded over the last dozen years. The diagnostic characters of this weevil species, its biology, current distribution in Europe and its prospects in Poland are discussed.
