TL;DR: Three fungi species tested increased mortality of larvae of pine defoliator Bordered White moth (Pine Looper), Bupalus piniaria (L.) (Lepidoptera: Geometridae) under laboratory conditions, with the most effective entomopathogene being B. bassiana.
Abstract: Fungi Beauveria bassiana, Metarhizium anisopliae and Isaria farinosa (local strains), were tested on 3rd and 4th instar larvae of pine defoliator Bordered White moth (Pine Looper), Bupalus piniaria (L.) (Lepidoptera: Geometridae) under laboratory conditions. Reared larvae were sprayed with the fungal suspension at a concentration of 1 × 108 conidia mL–1. All three fungi species tested increased mortality of larvae as compared to control (distilled water spray). The highest (100%) mortality was caused by B. bassiana within 12 days, followed by M. anisopliae: 18 days were needed to reach the same mortality level. The lowest mortality was caused by I. farinosa: even double spray resulted only in 56.67 ± 6.6% mortality. The most effective entomopathogene was B. bassiana.

TL;DR: In this paper, Dalia et al. report on the isolation and identifi cation of fungi developing on B. piniaria larvae, and show that the high percentage of cadavers containing one of the two fungal species and the low mortality recorded in the test could be due to the very diff erent sensitivity to the pathogens in diff Erent stage larvae.
Abstract: * Corresponding author. E-mail: dalia.peciulyte@botanika.lt Pine defoliator bordered white moth (pine looper), Bupalus piniaria L. (Lepidoptera: Geometridae) larvae were reared under laboratory conditions and were regularly supplied with pine twigs collected in nature for feeding. Cadavers of naturally infected 2nd and 3rd stage larvae were collected and analysed. Th irty-six fungal isolates belonging to 15 species and 10 genera were obtained, cultivated and identifi ed. Among them two species prevailed: Lecanicillium psalliotae (syn. Verticillium psalliotae) and Fusarium solani, comprising respectively 34.6 and 24.3% of the total number of fungi isolates. Conidial suspensions of the two fungi species at concentrations 105 to 108 conidia/ml were tested. Only the highest concentration of F. solani induced the mortality of 4th instar larvae, although the virulence was low: accumulative mortality ranged from 29.6 to 30.7% aft er 10 days of spraying. In the control group, the mortality was 15.8% aft er the same period. Th e high percentage of cadavers containing one of the two fungal species and the low mortality recorded in the test could be due to the very diff erent sensitivity to the pathogens in diff erent stage larvae. Th is is the fi rst report on the isolation and identifi cation of fungi developing on B. piniaria.

TL;DR: In this paper, the use of the red bordered white moth pheromone inducer has been discussed, which includes cis-5 trans-7 dodecadienoic alcohol, cis- 5 trans- 7 dodecadaic acetate and cis 5 trans 7 dodecaideic propionate.
Abstract: The present invention relates to one kind of red bordered white moth pheromone inducer, which has sleeve type rubber stopper carrier and hexane solution of the red bordered white moth pheromone dropped to the carrier. The said red bordered white moth pheromone includes cis-5 trans-7 dodecadienoic alcohol, cis-5 trans-7 dodecadienoic acetate and cis-5 trans-7 dodecadienoic propionate. The present invention also relates to the use of the red bordered white moth pheromone inducer. The inducer may be used in monitoring, preventing and trapping and killing red bordered white moth in various areas and countries.
