Each of the last three years, San Jose State's football season ended with a loss in a bowl game. This time there was a 41-39 five-overtime loss to South Florida within the Hawaii Bowl.

In the fifth extra time, the Bulls began with the ball and converted the 2 points with a reception from Keshaun Singleton. As SJSU attempted to reply, a pass from SJSU quarterback Walker Eget intended for Justin Lockhart was deflected, ending the ballgame.

The Bulls led 21-10 at halftime but were outscored 17-3 by the Spartans within the second half.

SJSU took its first lead after linebacker Noah McNeal-Franklin took the ball to the two-yard line following a 27-yard return.

The Spartans' freshman running back Lamar Radcliffe struck out and gave them the lead.

But Floyd Chalk IV, his fellow tailback, was stuffed on a third-and-1 on their final regulation possession, forcing the Spartans to punt with 53 seconds left.

A 13-yard return by USF's Sean Atkins put the Bulls in prime position to push downfield.

Six plays later, Bulls kicker John Cannon converted a 41-yard kick that sent the sport into extra time.

Each team scored in the primary three extra time periods and neither reached the tip zone within the fourth period.

SJSU wide receiver Matthew Coleman, filling in for 2024 Fred Biletnikoff Award finalist Nick Nash, led the Spartans with 119 yards on 12 receptions, including a touchdown in the primary extra time and a two-point conversion within the third third extension.

Eget was 33 of 58 passing with two touchdowns and one interception.

Take a walk on any of Hawaii Island's beaches in late summer and also you'll likely come across almond-shaped fruits lying on the sand. Known as false kamani nuts or tropical almondsThey fall from great, shadowy heights trees which line the island's many scenic ocean views.

What is probably not clear to the casual beachgoer, nevertheless, is that throughout the flesh of those inconspicuous fruits there may be a battle for survival. Tropical almonds are one in every of many lively battlegrounds within the war between a world agricultural pest, a parasitic wasp and a useful virus.

As an entomologist I study insect viruses and wish to decipher the complex interactions between insects and microbes. The findings could help researchers address global food security issues.

A worldwide pest challenge

At the middle of this conflict are invasive fruit flies from the family Tephritidae, lots of which have done this distributed across the globe and wreak havoc Hundreds of economic fruit and veggies.

There are several species of tephritid fruit flies in Hawaii invaded from the late nineteenth century. They caused large economic losses for fruit production over the islands. Scientists and fruit growers have undertaken it enormous efforts There has been no success in controlling these flies since their introduction, but they continue to be a serious economic problem.

A reliable control method was They release tiny insects called parasitic wasps into the wild, which might hunt and specifically destroy immature fruit flies. The term parasitoid describes an organism that spends its development as a parasite and ultimately kills its host.

Parasitoid wasps use an elongated stinger called an ovipositor drill into fruit where flies develop and pierce the fly's body to put an egg. Wasp eggs hatch contained in the fly host and regularly engulf your complete fly from the within out.

The use of parasitic wasps or other natural enemies by humans to regulate pest populations is generally known as biological controlor biocontrol. It was so successful in Hawaii that several species of parasitic wasps have established wild populations on the islands. They helped continuously suppress to this present day quite a few fruit fly pests.

The release of non-native insects for biological control could have unexpected negative consequences for local ecosystems. Therefore, federal agencies corresponding to the U.S. Department of Agriculture have done this strict regulations for brand new and existing biocontrol programs.

The enemy of my enemy is my friend

So how do wasps manage to cut back fruit fly pest populations? Once the wasp is placed in a fly host, it must turn to it The fly's immune systemwhich can attempt to suffocate the egg before it hatches.

This inhospitable environment has forced wasps to evolve Arsenal of microscopic substancesalso called molecular aspects, to combat fly defense. This features a cocktail of various molecules that the mother wasp introduces on the time of laying her eggs.

The goal of those aspects is manipulate the physiological processes of the fruit flycorresponding to its development from egg to adult and its immune response to invading parasites. By interacting with molecular components corresponding to proteins that make up the physiological signaling pathways of insects, parasitoid wasp aspects can delay insect host development and suppress host immunity in order that wasp offspring can feed on fly tissue unharmed.

This is the origin story of an unlikely partnership that has formed many species of parasitoid wasps useful viruses. Virus particles reproduce in large quantities during their development within the reproductive organs of female wasps. Wasp moms then use their ovipositor borer like a hypodermic needle to inject virus particles into host insects during egg laying.

The virus particles transform into biological weapons infect the cells of the wasp host. This infection disrupts processes corresponding to the fly's immune response. Evolving wasps profit from the virus's activity and reciprocate by passing the virus on to future generations of wasps.

Not all heroes wear capes

is a small, vivid orange wasp with a noticeably long ovipositor. The literal translation of longicaudata is “long-tailed” in Latin. But don't let his charismatic looks idiot you.

is wild in its ability to enjoy several species of fruit fly pestscorresponding to the Mediterranean fruit fly and the Oriental fruit fly. Pest control specialists world wide have the flexibility to regulate a wide selection of fruit fly pests released the wasps in agricultural ecosystems, where they reliably establish latest populations and ensure sustainable pest control.

Has formed like many parasitoids an alliance with a virus generally known as Diachasmimorpha longicaudata Entomopoxvirus or DlEPV.

DlEPV replicates within the venom gland of female wasps, which stores it there Billions of virus particles. Virus particles are packed so tightly there that they often result in the looks of the poison gland iridescent blue.

DlEPV particles are extremely deadly when injected into flies within the laboratory. The virus freezes the fly's development and multiplies with abandon until the fly finally dies.

In contrast, the alliance between wasp and virus is so strong that Cure wasps One of their resident DlEPV infections causes the wasp offspring to die contained in the fly hosts.

A brand new potential path forward

My colleagues and I published a study that shows that DlEPV could play a vital role in making a meal out of so many various fruit fly pests. We found an association between survival and DlEPV lethality in several fruit fly host species.

When we infected and flew with DlEPV, the virus successfully replicated and killed large numbers of fly hosts. However, DlEPV was unable to breed within the melon fly, a species of fly that wasps cannot use as a number.

These findings shed latest light on the impact of viruses on host-parasite rivalries. The presence of those viruses could influence how useful parasitic wasps are in controlling fruit fly pests. In the case of, the associated virus could also be liable for the a long time reliable help This wasp has contributed to fruit fly biological control programs world wide.

This work also revealed something latest potential tool within the fight against fruit fly pests. DlEPV is now known to be a deadly enemy for several of the world's most destructive pest species. If researchers can pinpoint how DlEPV exploits fly hosts on the molecular level, they might in the future incorporate the identical strategies this virus uses into latest methods of fruit fly pest control.
