Telenomus Podisi

Abstract Telenomus podisi Ashmead, 1893 is an important biocontrol agent, both in conventional and organic production systems. It can be used in association with other control strategies, such as natural botanical products and biological insecticides. Studies of selectivity and side effects are fundamental for proper management of insect control strategies because the interaction between different control strategies may negatively affect T. podisi. In this context, the present study evaluated the side effects of commercial natural products on T. podisi under laboratory conditions. Five natural products (insecticide, fungicide, and leaf fertilizer) allowed in organic farming were evaluated at concentrations recommended by the manufacturer in three bioassays. First bioassay (free-choice test), the preference of T. podisi parasitism between treated and non-treated E. heros eggs was assessed. In the second and third bioassay (no-choice tests) the treatments were applied to E. heros eggs, repectively before and after T. podisi parasitism (pre- and post-parasitism) and parasitism, emergence, offspring sex ratio, developmental time, and adult longevity were assessed. The products formulated with Metarhizium anisopliae (Metsch.) Sorok. (Hypocreales), Beauveria bassiana (Bals.) Vuill. (Hypocreales), orange oil fertilizer, and the fungicide copper oxychloride did not have side effects on T. podisi because they did not affect most of the evaluated characteristics. In contrast, azadirachtin A/B had a sublethal effect due to the reduced parasitism in all tests performed and, although it did not affect other aspects, this could compromise the performance of the parasitoid.

Main Strategy

ABSTRACT Telenomus and Trichogramma species stand out as agents for the biological control in rice crops, and the main strategy for preserving them is the use of selective pesticides. This study aimed at evaluating the toxicity of pesticides used in irrigated rice crop on Telenomus podisi Ashmead (Hymenoptera: Platygastridae) and Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae). Adults of these parasitoids were exposed to dry residues of pesticides, in a completely randomized experiment, with 25 treatments (24 pesticides + control) and four replications. The insecticides clorantraniliprole, flubendiamide and diflubenzuron and the biological insecticides based on Beauveria bassiana and Metarhizium anisopliae were harmless to T. podisi and T. pretiosum. The harmless herbicides were: 2.4-D amine, profoxydim, quinclorac, ethoxysulfuron and saflufenacil. The fungicide epoxiconazole + kresoxim-methyl was also harmless to these two biological control agents. Therefore, these pesticides are indicated for the integrated pest management, in flooded rice areas.

Cisplatin (cis-dichlorodiammineplatinum(II)) a potent antitumor agent is now available for the treatment of testicular and ovarian cancers. It is however, not free from its serious side effects including nephrotoxicity, gastro intestinal toxicity, myelosuppression, and ototoxicity. Here we now report that the drug produces peculiar bloating of the stomach in rats and induces acute ulceration.Wistar-derived rats weighing 200-250 g were administered cisplatin(9 mg/kg) ip as a single dose in 0.15 M NaCl. After 3 days the animals were sacrificed by decapitation. The stomachs were removed, the contents analyzed for pepsin and acidity. The inner surface was examined with a dissecting microscope after a moderate stretching for ulcers. Affected areas were fixed and processed for routine electron microscopy and enzyme cytochemistry.The drug treated animals kept on food and water consistently showed bloating and lesions (Fig. 1) with a frequency of 6-70 ulcers in the rumen section of the stomachs.

Cisplatin (CDDP) is currently one of the most valuable antineoplastic drugs available. However, it has severe toxic side effects of which nephrotoxicity is the major dose limiting factor in its use. It induces morphological changes in the kidney with hampered urine output. The present study is an effort to determine the influence of the drug on the neurohypophysis for any antidiuretic effects on the kidney.

Surgical Treatments

Severe drooling is associated with discomfort and psychosocial problems and may constitute a health risk. A variety of different surgical and non-surgical treatments have been used to diminish drooling, some of them with little or uncertain effect and others more effective but irreversible or with side effects. Based on clinical evidence, injection with botulinum toxin (BTX) into the parotid and submandibular glands is a useful treatment option, because it is local, reversible, and with few side effects, although it has to be repeated. The mechanism of BTX is a local inhibition of acetylcholine release, which diminishes receptor-coupled secretion and results in a flow rate reduction of 25–50% for 2–7 months.
