Trichogramma Dendrolimi

Thelytokous Wolbachia-infected Trichogramma species have long been considered as biological control agents against lepidopteran pests in agriculture and forestry. Wolbachia has been suggested to increase the probability of the superparasitism of Trichogramma, but the fate of infected offspring in the superparasitised host is still unknown. The present study aimed to evaluate the fitness of thelytokous Wolbachia-infected (TDW) and bisexual Wolbachia-free (TD) Trichogramma dendrolimi Matsumura (Hymenoptera: Trichogrammatidae) lines in superparasitised or single-parasitised hosts. The results showed that irrespective of whether Trichogramma wasps were developed from superparasitised or single-parasitised hosts, the TDW line was characterized by reduced fitness, including lower fecundity, shorter longevity, and smaller body size of F1 offspring, and lower emergence rate of F2 offspring than the TD line. This was not true for the survival rate and developmental time of F1 offspring. Additionally, the fitness parameters of T. dendrolimi that developed from superparasitised hosts were lower compared with that of T. dendrolimi that developed from single-parasitised hosts. Interestingly, Wolbachia-infected females had higher dispersal capacity than bisexual females when they developed from superparasitised hosts. The results indicated that Wolbachia negatively affects fitness of T. dendrolimi, but enhance dispersal capacity of T. dendrolimi females in superparasitism condition. Further studies need to be carried out to select the best line that will allow Wolbachia and their host Trichogramma to be better adapted to one another.

We analyze the role biological control plays in the Cuban agri-food system and discuss an experience at the country level that demonstrates that the pest problem can be handled through an ecological and sustainable approach. Biological control is one of the key components of a systemic approach that characterizes pest management. Its implementation has led to the removal of a group of highly dangerous pesticides from the Official List of Authorized Pesticides and reduced use of others. Greater emphasis has been placed on augmentative biological control, which is a tendency repeated throughout the world. In Cuba, rudimentary production occurs in 176 Centers for the Reproduction of Entomophages and Entomopathogens (CREE) located throughout the country; four industrial production plants are in operation, as are pilot plants and facilities in research centers. The biological control agents that are most reproduced are the parasitoids Lixophaga diatraeae (Townsend) (Diptera: Tachinidae) and Trichogramma Westwood (Hymenoptera: Trichogrammatidae), the entomopathogens Bacillus thuringiensis Berliner (Bacillales: Bacillaceae), and Beauveria bassiana sensu lato (Bals.-Criv.) Vuill. (Hypocreales: Cordycipitaceae); the antagonist Trichoderna Persoon (Ascomycota: Hypocreales: Hypocreaceae); and the nematodes of the Heterorhabditis Poinar (Nematoda: Rhabditida: Heterorhabditidae) genus. The use of predatory mites in inoculative strategies is limited due to their restricted availability, in spite of the fact that different alternatives have been evaluated for their massive reproduction with encouraging results. The achievements and progress obtained in classical and augmentative biological control and the changes in the understanding and thinking in Cuban agricultural have laid strong foundations for biological control through conservation of natural enemies. This latter strategy is greatly valued in sustainable agriculture.

Bemisia tabaci has become one of the major pests of economic importance that affects several crops worldwide. Among their natural enemies are found the Chrysopidae family, with larvae predators of different pests resulting very effective biological control agents. In order to contribute to possible use of this beneficial insect in B. tabaci biological control, the developmental time and survival of the immature stages of Chrysopodes (Chrysopodes) lineafrons was determined, as well as longevity and oviposition of the adults fed with eggs of B. tabaci. Chrysopodes (C.) lineafrons adults were collected in tomato crops in Lules department, Tucumán province. To determine the developmental duration for each instars and survival of the larvae, 90 eggs of C. (C.) lineafrons were randomly selected, of which only 71 eggs hatched; of these, 34 larvae were fed with B. tabaci eggs and 37 with Sitotroga cerealella eggs, used as control. The oviposition and longevity of the adults were recorded, both fed with the two preys. Chrysopodes (C.) lineafrons larvae consumed an average 127.04 (± 40.2) eggs of B. tabaci and 44 (± 19.04) eggs of S. cerealella per day. Mean developmental time of C. (C.) lineafrons fed with B. tabaci eggs was 45 (± 3.54) days and 35 (± 5.04) days with S. cerealella eggs. Survival of immature stages, number of eggs per adults and their longevity were higher when C. (C.) lineafrons were fed with S. cerealella eggs than with B. tabaci eggs. Chrysopodes (C.) lineafrons has proved to be an efficient predator which would represent an excellent tool for B. tabaci biological control in tomato crops.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
