Rhodomyrtus Tomentosa

Rhodomyrtus tomentosa is a perennial shrub native to Southeast Asia and is invasive in South Florida and Hawai’i, USA. During surveys of R. tomentosa in Hong Kong from 2013–2018 for potential biological control agents, we collected larvae of the stem borer, Casmara subagronoma. Larvae were shipped in stems to a USDA-ARS quarantine facility where they were reared and subjected to biology studies and preliminary host range examinations. Casmara subagronoma is the most recent Casmara species to be described from males collected in Vietnam and Indonesia. Because the original species description was based on only two male specimens, we also provide a detailed description of the female, egg, larva, and pupa. Finally, we conducted preliminary host range trials utilizing Myrtus communis, Myrcianthes fragrans, and Camellia sinensis. Casmara subagronoma emerged from M. fragrans, a Florida-native shrub, and larvae were able to survive in non-target stems for over a year (>400 days). Based on these findings and difficulty in rearing, we do not believe C. subagronoma is a suitable insect for biological control of R. tomentosa at this time, but may warrant further study. This investigation also illustrates the importance of host surveys for conservation and taxonomic purposes.

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.

Main Factors

This review summarized the duration of immature stages (egg to adult) and adult lifespans of the mites in the family Blattisociidae based on literature published from 1965 to 2021. We found 57 articles with information on the ecology and biology of the blattisociids. The lifespan and duration of immature stages were only reported in 16 out of 400 species. Most of the experiments were conducted in the laboratory, which may not accurately reflect their lifespans in nature. Temperatures, diets, and pesticides are the main factors that affect the lifespan of blattisociids. Low temperature could significantly prolong the lifespan and duration of immature stages of blattisociids. Different prey species or stages also affect the development time and lifespan of blattisociids significantly.

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). [...]
