Host Regulation

Abstract Background Venom is one of the most important sources of regulation factors used by parasitic Hymenoptera to redirect host physiology in favour of the developing offspring. This has stimulated a number of studies, both at functional and “omics” level, which, however, are still quite limited for ectophagous parasitoids that permanently paralyze and suppress their victims (i.e., idiobiont parasitoids). Results Here we present a combined transcriptomic and proteomic study of the venom of the generalist idiobiont wasp Bracon nigricans, an ectophagous larval parasitoid of different lepidopteran species, for which we recently described the host regulation strategy and the functional role of the venom in the induction of physiological changes in parasitized hosts. The experimental approach used led to the identification of the main components of B. nigricans venom involved in host regulation. Enzymes degrading lipids, proteins and carbohydrates are likely involved in the mobilization of storage nutrients from the fat body and may concurrently be responsible for the release of neurotoxic fatty acids inducing paralysis, and for the modulation of host immune responses. Conclusion The present work contributes to fill the gap of knowledge on venom composition in ectoparasitoid wasps, and, along with our previous physiological study on this species, provides the foundation on which to develop a functional model of host regulation, based both on physiological and molecular data. This paves the way towards a better understanding of parasitism evolution in the basal lineages of Hymenoptera and to the possible exploitation of venom as source of bioinsecticidal molecules.

AbstractParasitoid fitness depends largely on the capability to locate a host in an ecosystem. A parasitoid of a polyphagous host might not be able to find or to access the host in all its feeding niches. This study evaluated the niche selection ofHyssopus pallidus(Askew), a larval parasitoid ofCydia pomonella(Linnaeus), at the plant level with the goal of assessing its potential for biological control on different fruit crops throughout the plant cycle. Parasitoid behaviour during host location and reproduction rate were investigated on host caterpillars actively feeding on apple, pear, apricot or plum, and on caterpillars diapausing under the bark. Under laboratory conditions, the host searching behaviour ofH. pallidusvaried depending on the fruit species offered and the infestation of the fruits. Parasitoid females searched longer on apples than on other fruit species, and they searched longer on infested than on uninfested apples. Female wasps were able to locate and parasitize host caterpillars under the tree bark, and their behaviour did not vary with host accessibility. The numbers of caterpillars attacked byH. pallidusdepended on the fruit species. The highest numbers of caterpillars were parasitized in apples and apricots. Their accessibility (i.e. position) within the fruit or on the branch did not influence parasitism success. Although hosts were parasitized throughout the season, the best results were achieved with early and late releases. Therefore, the host niche selection behaviour ofH. pallidusmost likely co-evolved with the hostC. pomonellaon apples, which rendersH. pallidusa valuable biocontrol agent for successful release at different times of the season into apple orchards.

Limited information on typical Mandar culinary in Majene Regency, such as types of food, location of food, operating hours, and transportation are references to provide complete information to tourists. Information about typical Mandar food requires the role of technology in it, considering that it plays a very important role in helping tourists or local people to find information about Mandar specialties, it is requires a media capable of providing information about the address of the place to eat, the type of food served, the hours of operation, and transportation used. The purpose of this research is to design website information media on Mandar culinery touris in Majene regency that can help tourist or local communities.   Based on a series of research it can be conclude that the website information media on typical Mandar culinary tours in Majene Regency can make it easy for tourist or local people to get information about  the Mandar culinary tours and decide which restaurant wiil they choice.

Heliothis (Helicoverpa armigera) is a periodic pest of young pine trees (Pinus radiata) In response to a recent outbreak of this pest Microplitis croceipes a parasitoid of heliothis larvae was introduced into forests of the North Island volcanic plateau to augment biological control of heliothis A total of 13600 M croceipes pupae were released at monthly intervals over three seasons (199598) Successful overwintering of M croceipes populations confirmed establishment in the forests Mean monthly parasitism reached 107 in the third season Surveys at points radiating out from the release sites indicated that M croceipes was spreading at approximately 1 km per year
