Heteroperreyia hubrichi Malaise (Hymenoptera: Pergidae) is a primitive nonstinging wasp indigenous to northern Argentina and you can southeastern Brazil. Brand new biology, ecology, and host range of the latest sawfly H. hubrichi have been examined in Brazil, Florida, and you will Their state (Vitorino mais aussi al. 2000, Medal et al. 1999, Hight mais aussi al. 2002, Cuda mais aussi al. 2005). The latest larval phase of the insect was phytophagous (bush giving). Occupation studies compiled from inside the Brazil mean so it species is bivoltine (several years a year). Gender proportion of one’s people is roughly step one:step one (guys in order to ladies) whenever breeding was bisexual, nevertheless sawfly including displays arrhenotoky; mated girls develop people and you may unmated ladies write simply males. In Brazil, a great pupal diapause period occurs in summer time (December to help you March) and you may cold weather (Summer in order to August).

Through to emergence regarding pupal stage, females partner and you will/or oviposit inside young woody branches which can be next to the a great deal more tender terminal propels. This decisions permits this new sawfly to avoid the poisonous resin well-known throughout the Brazilian peppertree’s terminal increases. The female spends the girl noticed-including ovipositor to cut the new base structure and input this lady egg involving the narrow bark together with phloem, the new vascular muscle one transfers nutrition in the departs (Figure 3). New egg try elliptical fit and so are deposited top by side within the much time rows out of variable duration and number. Females display maternal behavior because of the guarding the fresh egg masses in the incubation period, however, die when the earliest larvae hatch.

The period out of eggs growth is mostly about fifteen weeks. Just how many eggs are actually connected to the size of eggs bulk. The average quantity of egg for each size is actually

Brazilian Peppertree Leaflet Roller, Episimus unguiculus

Episimus unguiculus Clarke, in earlier times labeled as Elizabeth. utilis Zimmerman (Lepidoptera: Tortricidae), is actually delivered toward Hawaii to possess traditional biological power over Brazilian peppertree regarding the 1950s (Krauss 1963). ) investigated new biology out of E. unguiculus in the process of establishing a research nest having carrying out servers variety screening inside a medication Fl http://datingmentor.org/escort/plano containment research. Adults (Profile 4) is actually short, grayish brown moths which have distinctive marks for the forewings. Whenever at rest, the brand new adults are cryptically coloured, like often forest bark or bird droppings. Average life span to your mature moths is 8 to help you 9 days, and you will innovation out of eggs so you can adult phase happens in from the 42 weeks.

Women normally put around 172 eggs throughout their life. Eggs are placed singly however, occasionally into the sets of right up to help you half dozen egg to the higher and lower surfaces off Brazilian peppertree literature. The brand new eggs, that are fixed for the leaflet, are compressed, ovoid, and you can light-green for the color having a flaccid chorion whenever first placed however, darken while they establish. The newest slim, scalelike shape and you will openness of freshly placed egg most likely pay for them particular protection from predation and maybe parasitism.

The fresh new caterpillar (or larval phase) of E. unguiculus (Contour cuatro) episodes the brand new leaves off Brazilian peppertree. Early instars are tan in order to light green during the colour, but because they visited readiness, the larvae turn bright red just before pupating and generally are up to 15 mm enough time. This new larval phase enjoys four instars, even when a sixth instar might result on occasion.

The fresh new adults is black colored that have red legs (Profile 3), and men and women are going to be broke up based on proportions (people is actually large), the presence of brand new ovipositor in women, and have now antennal morphology

Serving patterns of the larvae differ dependant on their age. Recently hatched larvae and you can early instars offer by scraping the outside of the pamphlets. Early instars was leaflet levels, and you will typically offer between young and you can expanding brochures that have been fastened in addition to cotton. The first to ever third instars generally online with her two or more adjacent pamphlets apartment against both. More mature larvae bind solitary leaflets to your feature cylindrical roll one is usually from the Elizabeth. unguiculus in the wild. A beneficial cohort of about 35 larvae can perform totally defoliating good 0.5 m extreme Brazilian peppertree potted plant in around three days (). The results off a recent study from the Manrique et al. (2009) revealed that large levels of defoliation by Elizabeth. unguiculus significantly shorter the amount of brochures, plant level, foliar biomass, cousin rate of growth (RGR), and you can capture:root proportion away from potted Brazilian peppertrees. Also, plant life were not able to recover from the results of one’s herbivory immediately following two months.
