The tomato leafminer Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most important pests of tomato worldwide. However, in spite of its tremendous economic importance, the success of environmentally friendly measures to control the pest is still limited. Study of physiological and behavioral parameters that affect pheromone production has provided useful information for pest management. Our results show no clear difference in pheromone production by females over the period from 2 h before to 2 h after the scotophase. However, pheromone production was clearly dependent on female age, with young females producing the highest amount of each pheromone component 10 days after emergence. In the presence of the host plant (physical contact and olfaction of the plant volatiles), virgin and mated females produced higher amounts of the major component of the pheromone (TDTA) than those in the absence of plant and those devoid of olfaction (antennectomized) but in physical contact with the plant. In electrophysiological experiments, TDTA elicited slightly lower responses on male antennae than the pheromone mixture. When stimulated at certain time intervals after the first exposure to TDTA, male antennae became more sensitive to the stimulus (sensitization effect). For the first time in an insect of the family Gelechiidae, we have found that females are able to detect their own pheromone (autodetection). Altogether, our results may represent a step forward in the knowledge of the chemical communication of this important pest.

Abstract First records of 151 species in the family Agromyzidae are presented for 40 countries and major islands in the Palaearctic Region (Russia being split into four subregions): from Afghanistan (1 sp.), Albania (15 spp.), Algeria (1 sp.), Andorra (2 spp.), Armenia (4 spp.), Austria (14 spp.), Balearic Islands (4 spp.), Canary Islands (2 spp.), China - Palaearctic part (2 spp.), Corsica (5 spp.), Crete (6 spp.), Croatia (16 spp.), Czech Republic (4 spp.), Dodekanese Islands incl. Rhodes (5 spp.), Egypt (1 sp.), European Russia (2 spp.), Finland (12 spp.), France (1 sp.), Georgia (1 sp.), Germany (14 spp.), Great Britain (2 spp.), Greece (4 spp.), Iceland (1 sp.), Iran (8 spp.), Israel (1 sp.), Italy (12 spp.), Jordan (6 spp.), Kyrgyzstan (6 spp.), Lithuania (2 spp.), Macedonia (2 spp.), Mongolia (2 spp.), Morocco (6 spp.), Netherlands (1 sp.), Norway (3 spp.), Oman (1 sp.), Poland (1 sp.), West Siberia (1 sp.), East Sibiria (3 spp.), Kamchatka (5 spp.), Sardinia (1 sp.), Slovakia (4 spp.), South Korea (13 spp.), Spain (10 spp.), Sweden (7 spp.), Switzerland (5 spp.) and Turkey (1 sp.). For a few species morphological details or plant genera from the collecting localities are added as possible host plants. Phytomyza parvicella (Coquillett, 1902) exhibits an extremely disjunct distribution, occurring in the high Arctic from Alaska to west Greenland and on the highest mountains of Germany and Poland. Other rare species with Boreo-alpine disjunctions are recorded. Cerodontha (Cerodontha) phragmitophila Hering, 1935 reached a tiny artificial patch of its host plant within the Sahara sand desert. The thermophilic mediterranean Phytoliriomyza pectoralis (Becker, 1908) was detected on the Swedish sun-blessed island Öland. Chromatomyia obscuriceps (Hendel, 1936) (emerged from Triticum crop) is specified as a valid species occurring from Iceland to Kamchatka. A new definition for Chromatomyia nigra (Meigen, 1830) sensu stricto is presented. The American Amauromyza (Cephalomyza) abnormalis (Malloch, 1913), a possible agent against the harmful neophyte Amaranthus retroflexus, was detected for the first time in the Palaearctic Region. Gnaphalium is attributed as a first detected host plant genus of Phytoliriomyza venustula Spencer, 1976.

Abstract The tomato leafminer Tuta absoluta (Meyrick) is one of the most devastating pests of greenhouse and outdoor tomato crops. Since it is a newly introduced pest in Iran, there is an important need to search for its natural enemies. In the course of a survey on the natural enemies of this pest, samplings were carried out in tomato greenhouses heavily infested with the tomato leafminer, in the Borazjan region of the Bushehr province in Iran. Leaves with mines were reared in the laboratory until emergence of parasitoids. A single parasitoid species of the family Eulophidae was reared and identified as Neochrysocharis formosus (Westwood 1833). This species is reported for the first time on the tomato leafminer in Iran. Such information may help in developing biological control programs to control this serious pest.

Investigation of Eriosomatidae in Belarus started in the 1900s. However, a regional checklist of Eriosomatidae aphids was not published till now. Based on material preserved in the collections of Belarusian State University and the Zoological Institute of the Russian Academy of Sciences, and data scattered across publications we have compiled the first comprehensive list of Eriosomatidae recorded from Belarus and briefly analysed it from the geographical and ecological points of views. The list includes 12 genera and 27 species. Pemphigus passeki Börner, 1952 has been recorded from Belarus for the first time. The registered diversity is less abundant than in the adjacent Poland. In the accordance with the global pattern of aphids host plant connections, a single species permanently inhabit woody plants (monoecious species), the other ones are dioecious and migrate from woody plants to woody (eight species) or herbaceous (12 species) plants. Four species is anholocyclic.

Extensive Damage

Abstract The tomato leafminer, Tuta absoluta (Meyrick), is a major worldwide pest of tomato crops, both in the greenhouse and in open field cultivations. Since this pest’s new introduction in Iran, it has caused extensive damage. Chemicals have mainly been used to control this pest. The purpose of our research was to identify the indigenous predators of the tomato leafminer, associated with tomato in the Borazjan region of the Bushehr province, Iran. From March to May 2014, infested tomato leaves were collected from protected tomato crops. A predator species from the family Miridae was found, reared, and identified as Nesidiocoris tenuis (Reuter 1895). This species is reported for the first time on tomato leafminer in Iran. Identification of important natural enemies provides a scientific basis for including these predators in the biological programs against this pest.

Critical Consideration

Initially, Oliver Twist (1839) might seem representative of the archetypal male social plot, following an orphan and finding him a place by discovering the father and settling the boy within his inheritance. But Agnes Fleming haunts this narrative, undoing its neat, linear transmission. This reconsideration of maternal inheritance and plot in the novel occurs against the backdrop of legal and social change. I extend the critical consideration of the novel's relationship to the New Poor Law by thinking about its reflection on the bastardy clauses. And here, of course, is where the mother enters. Under the bastardy clauses, the responsibility for economic maintenance of bastard children was, for the first time, legally assigned to the mother, relieving the father of any and all obligation. Oliver Twist manages to critique the bastardy clauses for their release of the father, while simultaneously embracing the placement of the mother at the head of the family line. Both Oliver and the novel thus suggest that it is the mother's story that matters, her name through which we find our own. And by containing both plots – that of the father and the mother – Oliver Twist reveals the violence implicit in traditional modes of inheritance in the novel and under the law.

Oleh karena itu perlu dibangun karakter buiding, sosial karakter suport untuk para ibu remaja dan keluarga sehingga terbangun interaksi yang baik dalam keluarga yang dilandasi dengan pendidikan dan pemahaman yang baik tentang Pendidikan seksualitas. Teen pregnancy is a pregnancy that occurs in adolescents aged less than 20 years old. Teen pregnancy provides many disadvantages for health, mental, psychological, economic well-being, career opportunities, poverty, and the future life. The aim of the study was to identify the determinants underlying teen pregnancy incidence. This study was a quantitative study with categorical analytic method. The study design used a case control with two comparison groups. The groups were control group and case group. The population in this study was all women who lived in the Wonosari, Sukosari, and Krajan Pandansari district and had or were pregnant for the first time at the age of less than 20 years old. Seventy three respondents were recruited using cluster sampling technique. The case group consists of women who were or had pregnant for the first time at the age of less than 20 years old and their children are currently aged ≤ 1 years old. The control group consists of women who were pregnant for the first time at the age of > 20 years old. The data was collected using a questionnaire. The findings showed that education, history of teen pregnancy in family and the age of marriage were related to the incidence of teen pregnancy after being controlled by information access. Low-educated respondents had 20.8 times higher chance of experiencing teen pregnancy; respondents with a history of teen pregnancy in the family had 4.9 times higher chance of experiencing teen pregnancy; respondents who were married at the age of < 20 years old had 12.1 times higher chance of experiencing teen pregnancy; respondents with poor understanding of condom use had 5.9 times higher chance of teenage pregnancy. In conclusion, the findings suggest to build good interactions in the family based on education and a good understanding of sex education.
