Comparison of classical and transgenic genetic sexing strains of Mediterranean fruit fly (Diptera: Tephritidae) for application of the sterile insect technique.

PLoS One 2018 14;13(12):e0208880. Epub 2018 Dec 14.

Insect Pest Control Laboratory, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, Vienna, Austria.

The development of genetic sexing strains (GSSs) based on classical genetic approaches has revolutionized the application of the sterile insect technique (SIT) against the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). The global use of Mediterranean fruit fly GSS for SIT applications as part of area-wide integrated pest management (AW-IPM) programmes is testimony to their effectiveness. During recent years, transgenic sexing strains (TSSs) have been developed through genetic engineering techniques offering the possibility to produce male-only progeny by introducing female embryonic lethal genes and to increase the efficacy to identify released sterile males by means of the expression of fluorescent transgene markers.

Social and ecological conditions of cranberry production and climate change attitudes in New England.

PLoS One 2018 12;13(12):e0207237. Epub 2018 Dec 12.

Earth and Environmental Sciences, Boston College, Chestnut Hill, Massachusetts, United States of America.

Cranberry growers in New England are increasingly pressured by negative effects associated with global climate change, some of which are familiar to this group (such as precipitation fluctuations and pest pressures), others that are rather new (such as warmer winters that threaten needed chill hours for the plants to bloom). The first study of this population of its kind, we use a survey, supplemented with observations and interviews, to assess Massachusetts cranberry grower attitudes towards climate change, and whether certain conditions of production might be associated with their attitudes. Our findings suggest that certain personal and ecological conditions are associated with greater worry of climate change effects, and that communal conditions of the cranberry grower social network provide some ways to cope with a warming climate.

Chemical activation of the ethylene signalling pathway promotes Fusarium graminearum resistance in detached wheat heads.

Phytopathology 2018 Dec 12. Epub 2018 Dec 12.

University of Lethbridge, Department of Biological Sciences, Lethbridge, Alberta, Canada ;

Plant signalling hormones, such as ethylene, have been shown to affect the host response to various pathogens. Often the resistance responses to necrotrophic fungi are mediated through synergistic interactions of ethylene (ET) with the jasmonate signalling pathway. On the other hand, ethylene is also an inducer of senescence and cell death, which could be beneficial for some invading necrotrophic pathogens. Read More

Generating Homo- and Heterografts Between Watermelon and Bottle Gourd for the Study of Cold-responsive MicroRNAs.

J Vis Exp 2018 Nov 20(141). Epub 2018 Nov 20.

Institute of Vegetables, Zhejiang Academy of Agricultural Sciences; State Key Lab Breeding Base for Sustainable Control of Plant Pest and Disease, Zhejiang Academy of Agricultural Sciences;

MicroRNAs (miRNAs) are endogenous small non-coding RNAs of about 20 - 24 nt, known to play important roles in plant development and adaptation. There is an accumulating evidence showing that the expressions of certain miRNAs are altered when grafting, an agricultural practice commonly used by farmers to improve crop tolerance to biotic and abiotic stresses. Bottle gourd is an inherently climate-resilient crop compared to many other major cucurbits, including watermelon, rendering it one of the most widely used rootstocks for the latter. Read More

Effect of spraying direction on the exposure to handlers with hand-pumped knapsack sprayer in maize field.

Ecotoxicol Environ Saf 2018 Dec 4;170:107-111. Epub 2018 Dec 4.

Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing 100193, China. Electronic address:

Only less than one percent applied pesticides reach the target pest, the remainder spread out into the environment, effecting on workers, bystanders, consumers and so on. Handlers with manual knapsack sprayer are completely exposed to the pesticide spray plume when they deal with the pesticides. Those kinds of sprayer are widely used in developing countries, more than 75% of farmers using hand-pumped knapsack sprayer in China, yet rarely systematic studies had been focused on the typical applying scenario.

Queen Venom Isosolenopsin A Delivers Rapid Incapacitation of Fire Ant Competitors.

Toxicon 2018 Dec 4. Epub 2018 Dec 4.

Red Imported Fire Ant Research Centre, South China Agricultural University, Guangzhou, 510642, PR China.

Fire ant venom contains insecticidal alkaloids named 'solenopsins'. Whilst species-specific differences are reported, little attention has been given to caste-specific venom adaptations. The venom of fire ant queens has remained particularly poorly studied, though studies have shown it to be strikingly similar across different species, in being primarily composed of the alkaloid isosolenopsin A, regardless of chemical configuration in workers.

Sporadic short temperature events cannot be neglected in predicting impacts of climate change on small insects.

J Insect Physiol 2018 Dec 5. Epub 2018 Dec 5.

Climate Change Biology Research Group, State Key Laboratory for Biology of Plant Diseases and Insect Pests, Inst. of Plant Protection, Chinese Academy of Agricultural Sciences, No 2 Yuanmingyuan West Road, Haidian District, CN-100193 Beijing, PR China. Electronic address:

Climate warming is characterized by increase in extreme heat events (EHEs). EHEs and mild temperature periods alternate with each other and form complex climate scenarios. Among these scenarios, low-frequency and short-duration extreme heat events during long mild periods (sporadic short EHEs) and low-frequency and short-duration mild periods during long extreme heat events (sporadic short mild periods) commonly occur in nature.

Sand crickets (Gryllus firmus) have low susceptibility to entomopathogenic nematodes and their pathogenic bacteria.

J Invertebr Pathol 2018 Dec 5;160:54-60. Epub 2018 Dec 5.

Department of Nematology, University of California Riverside, Riverside, CA 92521, USA. Electronic address:

The entomopathogenic nematode, Steinernema scapterisci, a specialist parasite of crickets, has been successfully used to combat the southern mole cricket, Neoscapteriscus borellii, which is an invasive pest of turf grass. As an entomopathogenic nematode, S. scapterisci causes rapid death of the insects it infects and uses bacteria to facilitate its parasitism. Read More
