Caste Differences

Wasps of the genus Polistes have a number of characteristics that make them particularly suitable for studies on insect social behaviour. The females construct nests with exposed combs, have a reasonably complex social behaviour, and usually lack obvious morphological caste differences. In addition, the adults of many species establish colonies as groups of siblings (foundress associations), a method which is intermediate between colony founding by swarming, and colony founding by individual queens (Wilson 1971). Because of these characteristics, Polistes have been of interest to biologists who are concerned with the evolution of social behaviour in insects (e.g. Alexander 1974, Gibo 1974, Lin and Michener 1972, West 1967, West Eberhard 1969, 1975). Consequently, there is a need for a simple technique for rearing various species of Polistes under controlled conditions. Gibo (1974) briefly described modifications of Gillaspy's (1971) rearing method for P. apachus which made mass rearing of P. fascatus possible. This note describes the modified method in greater detail, and includes improvements that have resulted in increased yield and greater synchrony of colony growth. The improvements have been developed over 3 years and the method has been used to rear more than 100 colonies of various species of Polistes, including P. fuscatus, P. apachus, and P. dorsalis.

AbstractProtein fed to adults of the carrot rust fly, Psila rosae F., enhanced oviposition: the addition of yeast hydrolysate to the sugar diet resulted in a 50% increase in oviposition, giving an average of 75 eggs per female.A description is given of a simple oviposition device, which allows normal oviposition (compared with sand).Carrots planted in sand gave best rearing results when inoculated with eggs 14 days after insertion. Germinating carrot seeds placed on top of the sand improved the rate of development of the eggs to pupae from 40% to 62%.

Ceratovacuna Lanigera

Ceratovacuna lanigera Zehntner (Hemiptera: Aphididae) is a destructive insect pest of sugarcane that is responsible for reducing the quality, yield, and sugar content. Ecofriendly methods of pest control, such as the use of biological control, is encouraged since it does not exhibit the harmful effects that are usually seen when using chemical-based pesticides. Here, we evaluated the efficacy of several entomopathogenic fungi isolates against C. lanigera under laboratory conditions. A total of seven isolates were obtained from agricultural soils that were collected from various locations from Sabah, Malaysia, using the insect bait method. Among the seven, four isolates (TMS114, TMS623, TMS628, and TMS707) were positively identified as T. harzianum (Hypocreales: Hypocreaceae), two isolates (TMS45, TMS321) as T. asperellum (Hypocreales: Hypocreaceae), and one isolate (TMS633) as T. hamatum (Hypocreales: Hypocreaceae) based on a combination of morphological characteristics and molecular data using ITS 1-5.8 S-ITS 2 regions of the rDNA. Four different concentrations (1 × 105, 1 × 106, 1 × 107, and 1 × 108 mL−1) of conidia suspensions of the isolates were applied separately on nymphs and adults of C. lanigera. The results showed that mortality in both nymphs and adults was dependent on the conidia concentration and exposure time. Among the four concentrations, the highest mortality of C. lanigera was found to range from 59.99 to 75.70% for nymphs after 72 h and from 57.45 to 72.31% for adults after 6 days of treatments at the concentration of 1 × 108 conidia mL−1. Trichodermaharzianum (TMS623) showed significantly highest mortality of 75.70% for nymphs and 72.31% for adults among the seven isolates. . However, the nymph and adult mortality rates for the isolates were 70.00% & 68.00% for TMS114, 66.42% & 63.10% for TMS628, 67.85% & 65.24% for TMS707, 61.42% & 58.80% for TMS45, 59.99% & 57.45% for TMS321 and 63.56% & 60.91% for TMS633, respectively. For nymph mortality, T. harzianum (TMS623) showed a LC50 (lethal concentration) value of 6.30 × 105 conidia mL−1 and LC90 value of 3.01 × 109 conidia mL−1, respectively, and for adult mortality, the values were found of 6.16 × 105 conidia mL−1 for LC50 and 2.23 × 1010 conidia mL−1 for LC90, respectively. The lethal time (LT) values for nymph and adult mortality were found of 42.65 h and 3.89 days for LT50 and 93.32 h and 8.70 days for LT90 by T. harzianum (TMS623). Therefore, T. harzianum (TMS623) showed more pathogenic potential against C. lanigera and can be further applied to determine its efficacy under field conditions. To our best knowledge, this is the first report of T.harzianum,T.hamatum, and T.asperellum species that are used as entomopathogenic fungi against sugarcane woolly aphid, C. lanigera.
